For app founders, indie makers, and growth teams
AI video generator for a mobile app, built from your URL
Your app is motion, taps, and delight, but a strip of frozen screenshots hides all of it. Paste your app landing page and Rendrio reads it, writes a six scene script, and builds a branded motion promo with AI voiceover and music. No timeline, no motion designer, no lost weekend inside export settings. Download an MP4 sized for paid social, launch posts, and store listings in about a minute.

The problem
Static screenshots cannot show a tap
An app lives in the swipe, the onboarding flow, and the payoff moment. A carousel of still frames strips out the exact thing that makes someone install. People scroll past a frozen strip in under a second, so the feature that would have converted them never gets seen in motion.
One promo costs more than a month of ad spend
A freelance motion designer runs 500 to 2,000 dollars for a single sixty second app promo, and agencies quote 4,500 to 6,500 across two weeks and three revision rounds. For a solo founder shipping on a launch deadline, the economics never work for one clip, let alone the many you actually need.
Paid UA eats creative faster than you can make it
Growth teams now test dozens of ad variations a month, not a few polished cuts a quarter. Each angle gets a small budget for a few days before it fatigues. Producing that volume by hand, or paying 150 to 200 dollars per UGC video, drains the budget you meant to spend on installs.
You opened a video editor and closed it
Empty timeline, mystery keyframes, audio that will not sync. Editing software is a full second skill set you never signed up to learn. You wanted a finished promo for your app, not a render queue and a codec error at midnight.
Store listings punish a boring first frame
On Google Play the promo video is the first thing a visitor sees, ahead of your screenshots. A flat intro or a logo held too long loses the install before your value proposition ever loads. The opening three seconds decide whether anyone keeps watching.
Every channel wants a different shape
A 9:16 cut for TikTok and Reels, a 1:1 for feed ads, a 16:9 for your website hero and YouTube pre roll. Recutting the same story into three ratios by hand is busywork that multiplies with every new placement you want to test.
What a Mobile App video is for
Paid user acquisition on TikTok and Meta
Generate a hook driven 9:16 promo for install campaigns, then switch the tone to hype and render again to test a second angle. Small budgets per variation reward volume, and at nine dollars a render you can put real creative behind the winners instead of betting the quarter on one cut.
Google Play store listing video
Play lets you feature a public YouTube video on your listing, shown before your screenshots. Render a tight promo that opens on your core outcome, upload it to YouTube with monetization off, and paste the full video URL into Play Console alongside your feature graphic.
Product Hunt and Show HN launch day
Pin a sharp 16:9 video to the top of your launch post. Hook, features, and a clear call to action give hunters the thirty second story they need before they upvote, comment, and share your app with their own audience.
Pre launch waitlist and landing page hero
You do not need the app live in a store yet. Many founders generate a promo before launch to seed a waitlist. If your landing page shows the value and some screens, Rendrio can build the video that turns visitors into early signups.
Investor updates and cold outreach
Drop a thirty second promo into a fundraising email or a partnership pitch. A moving product reads as further along than a deck of static mockups, and it costs you one render rather than a designer booking.
How to make a great Mobile App video
Open on the outcome, not the logo
Rendrio writes scene one as a hook. Give it a landing page whose headline states the core result your app delivers, so the AI can build the whole promo around a promise instead of a splash screen. The first three seconds carry the whole ad on a feed.
Feed it your best current screens
The visuals come from the screenshots and brand colors on your URL. Put high resolution, up to date product shots on your landing page so the generated promo matches exactly what a user sees the moment they open the app.
Match the ratio to the placement
Use 9:16 for TikTok, Reels, and store previews, 1:1 for feed ads, and 16:9 for your website and YouTube. The Pack renders all three from one generation, so you never regenerate just to fit a new channel.
Treat renders as test variations
Since a render is nine dollars, make two or three cuts with different tones and open lines, then let the cheapest cost per install decide the winner. That mirrors how growth teams run creative testing without a studio budget.
Questions
Can Rendrio make my App Store preview video?
Apple requires App Store preview videos to be actual footage captured from within the app, 15 to 30 seconds at your device resolution. Rendrio builds branded motion graphics from your landing page, not screen recordings, so it is not meant for that specific slot. It is built for the ads and launch assets around your app: paid UA, Product Hunt, Google Play, and social.
Does it work for a Google Play listing video?
Yes. Google Play features a public YouTube video on your listing, and a Rendrio promo fits well. Render your video, upload it to YouTube with monetization turned off, and paste the full video URL (not a shortened link) into Play Console. Keeping the cut under thirty seconds matches how listing visitors watch.
How long is the finished video?
Rendrio produces a promo under sixty seconds built on a six scene structure: hook, problem, solution, features, social proof, and call to action. That length matches how people watch app ads on TikTok and Reels and how store visitors sample a listing before installing.
Do I need my app live in the store first?
No. You only need a working landing page or website URL. Many founders generate a promo before launch to build a waitlist or seed Product Hunt. As long as the page shows your value and some screenshots, Rendrio can build the video.
How much does one video cost?
The preview is free with no credit card. A Single Render is nine dollars for one aspect ratio, and the Pack is twenty nine dollars for five renders across all three ratios. There is no subscription, and credits never expire. For comparison, a freelance app promo starts near 500 dollars and agencies charge several thousand.
Can I make several ad variations to test?
Yes, and that is a common use. Each render is nine dollars, so you can generate multiple cuts with different tones, hooks, and ratios, then run them as separate creatives and keep whichever drives the cheapest installs. It is built to give paid UA teams volume without a per video studio bill.
