Rizz.app review: what the app does and how it compares to ProRoast

The word "rizz" entered everyday speech at roughly the moment language models learned to write jokes. Commercially, that timing was a gift. The app carrying the name has passed five million installs on Google Play alone and holds a 4.8 rating on both stores — numbers almost no other dating helper can show.

So let's look inside. And while we're there, let's find the line between "hand me a line" and "explain why the conversations aren't happening in the first place."

What Rizz.app actually is

The publisher is TREND IT LLC, an American company, and the credits sit right in the store description: Joshua Miller and Roman Khaves. On the App Store the listing is simply RIZZ, filed under Lifestyle. On Google Play it is the same product from TrendIt. The website at rizz.app is nearly empty — a logo, two store buttons, a few social links. Everything that matters happens inside the app.

The pitch fits in one sentence. You show the app a conversation, it hands back replies. The team calls it an AI wingman, the friend standing behind your shoulder telling you what to say.

The audience for that is enormous. Age rating is 13+ on the App Store and 3+ on Google Play, which is a curious detail in itself — two stores looked at one product and graded it differently. Ten languages are supported.

How it works day to day

The core loop is short. Screenshot a chat, drop it into Rizz, pick a mood, receive a handful of ready-made lines. You can feed it a match's bio instead of a conversation, and it will write an opener.

There are modes beyond flirting. The developers explicitly mention a formal option for networking and professional messages. Whether anyone uses it is another question, but it exists.

The app also claims to adapt to how you write, studying your tone, humour and vocabulary so replies sound like you. The marketing line is confident — the more you use it, the better the results get. In practice this reads as style configuration rather than a model trained on you personally.

One detail is easy to miss. The same company ships a second app, Rizz! The Ultimate AI Keyboard, which puts suggestions directly into the text field. In other words, the ability to answer without switching between windows lives in a separate product with a separate price.

The genuine strength: speed

Credit where it's due. Rizz does its one job quickly and without ceremony. Open, paste, read five options, copy. Twenty seconds, start to finish.

For someone frozen over a message with no idea what to send, that works. Instant unblocking. Most positive store reviews describe exactly this — conversations became easier to hold, confidence went up.

The narrowness is the reason for the popularity, not a flaw in it. One button, one output, nothing to learn.

Where the scope ends

Now the other side.

Rizz works with text. Only text. It never looks at your photos, never tells you which shot belongs in the first slot, never touches your bio, and never explains why people swipe past your profile.

That matters, because messaging is the last step in the chain. You have to reach it. When the profile is put together badly, clever replies have nowhere to land — there are no conversations because there are no matches. The app helps enormously if your chats are already running, and barely at all if they aren't.

The second limit is feedback. Rizz produces lines but never explains the conversation. Is the other person interested? Is it time to suggest meeting? Is your pace starting to read as pushy? Are you talking to someone who will ask for money in two days?

That last one deserves emphasis. Romance scams follow a recognisable script: a fast move to another messenger, refusal to take a video call, an urgent financial story. A reply generator flags none of it. It will cheerfully keep the conversation warm with anyone, including the person working you. The pattern is broken down in our guide to dating app scammer signs.

Third, the replies are written in a vacuum. The app sees a screenshot but knows nothing about you — how your profile looks, what you're actually after, how you normally sound outside this one chat. Hence the most common complaint in reviews: the lines feel generic.

One of the longest App Store reviews makes precisely that case — the pick-up lines read as canned, the pool is small, and there's no way to tailor them. It doesn't cancel the average rating, but the experience recurs often enough to mention.

How to spot a generated reply

Anyone who spends a fortnight with a tool like this picks up a side skill: telling a human line from a machine one. Useful when you're writing, and just as useful when someone writes to you.

The first tell is excessive polish. People type unevenly. They trail off, drop a bracket instead of a full stop, answer in one word. A generated line is almost always complete, balanced, and a touch longer than it needed to be.

The second is the compliment with no address. "You've got great energy" fits anyone, which means it says nothing. A real observation attaches itself to a specific photo, a phrase from a bio, the previous message.

The third is the question asked out of duty. The model knows conversations must keep moving, so it ends every line with a question mark. Five messages in, that stops resembling curiosity and starts resembling a form.

Which gives a practical rule worth more than the subscription: damage every suggested reply before you send it. Cut a sentence, swap one neutral word for yours, leave the typo in. The line comes alive immediately.

This is also why ProRoast shows the hook behind every opener it writes. You see the text and the reasoning — which detail it grabbed and why. Harder to copy blindly, easier to fix when the phrasing isn't yours.

What it costs

This is the part to read slowly.

The download is free and a subscription gates the rest. Publicly reported figures put a trial week ahead of roughly seven dollars per week, with a monthly option near twenty. The App Store listing shows in-app purchases spanning 3.99 to 99.99 dollars, including an annual tier around seventy.

Numbers drift by region and promotion, so treat them as a bearing rather than a price list. The checkout screen inside the app is the only authority.

The limits matter more than the sum. Reviews return again and again to a pattern of five replies followed by a week of waiting or a payment prompt. Some users report being asked to subscribe while a subscription was already active. Neither complaint is unique to this app, but in dating the sting is sharper — the help is needed tonight, not next Tuesday.

What the app knows about you

Privacy deserves its own paragraph here, because the material in question is somebody else's messages.

When you upload a chat screenshot, you send in a stranger's words along with your own, and that person never agreed to it. This is true of every screenshot-based reply generator, not just this one.

On Google Play the developer states the app may collect financial info, photos and videos, and three further data types. Nothing is shared with third parties and data is encrypted in transit. But one line reads "data can't be deleted" — there is no built-in way to ask for everything collected about you to be wiped.

The App Store card fills in the rest: identifiers may be used to track you across apps and websites owned by other companies, while user content, identifiers, usage data and diagnostics are collected without being linked to your identity.

None of this is unusual. Half the market runs the same way. Set against ProRoast's own store card, though, the contrast is sharp: the collected list there is identifiers and diagnostics, with no user content, no photographs and no financial data. The difference comes from how the product is built — face detection runs on the device itself, anything cloud-bound goes only after explicit consent, and content isn't kept on the app's servers.

The age ratings diverge too: 4+ for ProRoast against 13+ for Rizz on the same store.

What ProRoast does instead

ProRoast started from a different question. Not "give me a line" but "work out why this isn't landing and show me what to fix."

The difference in scale is immediate. Rizz covers one stretch of the road — the moment you need to say something back. ProRoast covers all of it: photos, description, first message, the arc of a conversation, the timing of an invitation, and a read on the pair. Eight tools against one, and that isn't a marketing count but a list of separate screens with different logic behind each.

Photos. The app compares up to six shots, scores them on quality, background and smile, ranks them, and names the one that belongs first. The first assessment takes about thirty seconds and needs no account. Face detection runs on the device, and cloud analysis only starts after you explicitly agree. Details on the Photo Analyser page.

Bio. The Bio Editor writes a description for a specific platform in a chosen tone, or rewrites the text you already have. Length limits are built in, so nothing needs trimming afterwards.

Profile score. The whole profile collapses into a number from 0 to 100, followed by a fix list ordered by impact — what to change first for the fastest visible shift. The mechanics live in the profile analyser.

Openers. You show the app someone's profile. It pulls out hooks — the guitar in the background, the dog, the country from a holiday photo — and builds three first messages in different tones on top of them. Each one displays the detail it rests on. That's the Opener generator.

Conversations. The Chat Analyser reports likely interest, ghosting risk, whether the moment for a date invitation has arrived, a read on both communication styles, and scam indicators. Replies come from the same screen.

Keyboard. Suggestions and a greeting bank work inside any app's text field — Tinder, Telegram, WhatsApp. No separate purchase. The keyboard never reads the clipboard on its own: text reaches it only when you press the system paste button.

Practice mode. Nine AI characters with distinct personalities let you rehearse an opener, a joke or an awkward question. Mistakes cost nothing real. A browser version runs without installing anything — the AI chat trainer.

Compatibility. A five-area read on a pair, meant as a conversation starter rather than a verdict. It also runs in the browser.

On money: what one subscription covers

ProRoast publishes no tariff on its store card, so I won't pretend to compare sums directly. What can be compared is composition, and in subscription products that decides as much as the number.

Rizz keeps its keyboard in a second app. Want suggestions inside the text field, and you download a separate product and pay for it separately. ProRoast's keyboard ships inside the app alongside everything else — photo analysis, the bio editor, the profile score, openers, chat analysis, the practice mode and compatibility.

The entry point differs too. Rizz offers a trial week, after which the door closes. ProRoast returns a first photo score in about thirty seconds with no subscription and no account, so you can see what the app actually produces before paying anything. Several tools live on the website and run free in a browser: the chat trainer, the compatibility calculator, numerology and a handful of tests.

Which gives a simple conclusion. One subscription buys a set that, on the other side, splits across two apps and still covers less ground.

A young app with real momentum

Here it's worth being honest all the way, or the comparison stops being one.

Rizz has been on the market since 2023 and has gathered five million installs. ProRoast arrived considerably later: the App Store shows version 1.9, the first reviews are dated July, and the app is iPhone-only, requiring iOS 18. Reviews number in single figures. By store metrics these are not comparable weight classes, and pretending otherwise would be silly.

The more interesting question is what the young app turned up with.

The usual startup path in dating goes: ship a reply generator, then build the rest if it takes. ProRoast launched with the entire funnel, two languages, its own keyboard and a practice mode with nine personalities. Version 1.9 in a matter of months means the bio algorithms, the greeting bank and the tone settings are being rewritten release to release.

In my experience this is the case where a product's age tells you less than its architecture. Catching up on features is hard — that means rebuilding foundations. Catching up on install counts is easier, being mostly a question of time and marketing budget.

Feature comparison

The table is lopsided, and that isn't a rhetorical trick. Of eighteen rows, eight belong to ProRoast alone and exactly one to Rizz alone.

The cause is the question each product set itself. Rizz is a reply generator pushed to the limit of speed, and within that lane it's good. ProRoast is a read on the full funnel, from the first photograph to the moment it makes sense to suggest coffee. Comparing them on messaging suggestions is like comparing a knife to a kitchen on how well it chops an onion.

Which one fits you

Rizz makes sense in one scenario: the conversations already run, the matches exist, and the only friction is wording. You stall over the text field and want a fast generator on hand. Its formal mode for work messages is a genuine extra — ProRoast has nothing like it and doesn't plan to, the focus there being dating alone.

In every other situation the choice is plainer than reply-generator makers would like. Few matches, or none. Conversations dying on the third message. No clear idea what's wrong with the profile. A wish to see what's happening in a chat rather than only what to type next. Rizz addresses none of that constructively, because it looks at neither the photos, nor the description, nor the shape of the conversation.

In my experience the second case is many times more common. People arrive looking for lines and discover the problem was the first photo and a bio that could belong to anyone. Lines don't fix that. Which is exactly why an assistant that sees the whole profile produces results a reply generator can't reach — not because the model is cleverer, but because it has context on the input.

Neither tool replaces your own judgement, of course. An assistant helps you find your register faster and stops you spending an evening rewriting one message. After that it's still you.

Short answers

Is Rizz.app free?

The download is free, but the useful features sit behind a subscription. Publicly reported pricing puts a trial week ahead of roughly seven dollars per week, with monthly access near twenty. Prices vary by region, so the checkout screen is the real answer.

Who makes Rizz?

TREND IT LLC, based in the United States. The store description credits Joshua Miller and Roman Khaves. The rizz.app site works as a shop window with links to both stores.

Is uploading chat screenshots safe?

A screenshot contains another person's messages, sent without their consent. The developer says data isn't shared with third parties and is encrypted in transit, but there's no delete-my-data control and identifiers may be used for tracking. If a conversation is sensitive, crop it before uploading.

How is ProRoast different from Rizz?

Scope. Rizz generates replies from a screenshot and stops there. ProRoast does the same and additionally scores photographs, writes and edits bios, rates the profile from 0 to 100, reports the other person's interest and your ghosting risk, checks conversations for scam patterns, and lets you rehearse with nine AI characters. The suggestion keyboard is included rather than sold as a second product. It also collects less: identifiers and diagnostics rather than user content, photos and financial data.

ProRoast is brand new — is it trustworthy?

The app is genuinely younger: version 1.9, first App Store reviews dated July, iPhone-only on iOS 18. Install numbers trail Rizz by orders of magnitude. Checking it costs nothing, though — the free photo score takes about thirty seconds and needs no account, and the chat trainer, compatibility calculator and tests run straight in a browser. Judge it on output rather than on the star count on a storefront.

Do these apps actually help?

They remove the freeze and save time, but they can't manufacture interest that isn't there. Results usually shift because of the profile — first photo, description, a reason to write. The tool speeds up the route. You still pick the direction.

Should I use both?

You can, though there's little point. Everything Rizz is bought for exists inside ProRoast, and the reverse isn't true. Two subscriptions for one overlapping scenario is not the line item to defend.
