Start a project and add your captures
Create a project, then add the raw screenshots straight from your phone or simulator. Screentrino keeps captures organised per device, so your phone and tablet screenshots never get mixed up.
- Add one set of captures per device size you need to support
- Reorder slides by dragging them in the filmstrip
- Swap a capture later without losing the styling you've already applied
Pick a template and make it yours
Start from one of the built-in templates, then adjust the frame, background and typography until it looks like your brand rather than a template.
- Start from one of 79 templates, then choose from 18+ background styles, from soft gradients to blueprint grids
- Double-click anything on a slide to open its settings
- Pick a device frame and drop in a badge — star rating, laurel or pill
- Adjust typography: weight, spacing, alignment and colour, with 25 embedded typefaces
- Made a change you didn't mean? Undo goes back 60 steps
Write and translate your text
Write the headlines yourself, or let AI draft them. Then add the languages you sell in, and Screentrino translates every slide for you.
- Write with AI: describe your app or paste its store link, and it reads your screenshots and writes the headline, subtitle, note and stickers for each slide (30 runs a day)
- Translate into 25 languages, one at a time or all at once. Notes, stickers and badges are translated too
- Translation uses credits, about 60 per language for a full set of 10 screenshots: 150 a day for free, 2,000 with an export pass, or 6,000 a month on a monthly or annual plan. You see an estimate before you start
- Every line stays editable, so you can fix any word by hand
Sign in to keep everything synced
Sign in once and your projects follow you between devices — start styling on your laptop in the evening, and pick it back up on your phone the next day.
- Sign in with Google in one tap
- Changes save automatically as you work
- Your App Store Connect and Google Play keys stay in the browser you added them to
Export or send to the stores
Preview is always free, with a watermark, and you can see how your set will look in App Store search and on a Google Play listing. When you're ready, an export pass or subscription unlocks the full-resolution ZIP and uploading straight to the stores.
- Every required size for the App Store and Google Play, generated automatically
- Alpha-free PNGs — no transparency issues on upload
- Everything bundled into one ZIP, ready to drop into App Store Connect or Play Console
- Or skip the ZIP: open Export, and under Send to the stores choose App Store Connect or Google Play. Add your key once, pick your app, and every language and size is uploaded in slide order
- On the App Store, the version must be in Prepare for Submission. On Google Play, everything goes up as one draft that's only saved if every image made it. Check your listing before you submit it for review
- The first time you export or upload with a paid plan, you'll confirm that your right to cancel ends once your files are created and downloaded or sent to a store. Until then, you can get a full refund within 14 days
