Hi. I'm a developer, just like you. One purchase and the app is yours. I've been a dev for over 30 years. And one of the many challenges is making video previews, so I built this app to make our lives easier! I'm using it every day right now, so the idea is to keep making it better and better. I build it for myself first, then I put it on the store! Hope it helps you, and if you think of any feature that would be good, send me an email, I'd be happy to hear from you! What AppTrailer does for you: Live video editor. Import your recording and build the cuts on the spot: drag the filmstrip, set In/Out, duration and speed per clip. The preview updates as you edit. Robot assistant. It cleans the dead time out of your recording, signs the video at the end, and swaps the source without losing your work. It proposes, you confirm. Text with impact. One phrase per cut, with font, color, background band and 7 entrance animations. Spotlight. A smooth zoom that highlights the right spot on screen. Music & SFX. Background music (OpenGameArt CC0) and sound effects per cut (Kenney, Mixkit). Or import your own. Screenshot editor. Pick the best frame of each screen, finish it with text, stickers and a device frame, and generate a set per language, translated right on the device. The right format, always. Everything comes out in the exact size and format App Store Connect accepts, on iPhone and iPad. No rework. FAQ What is AppTrailer? It's the app that turns your app's screen recording into the preview video (App Preview) and the screenshots the App Store asks for, all done right on your iPhone or iPad. Why do I need this? Apple requires the App Preview and screenshots in very specific sizes and formats. Putting that together in a regular editor is slow and almost always comes out off spec, so your upload gets rejected. AppTrailer delivers everything in the exact format App Store Connect accepts. How does it work? You record your app's screen and import it into AppTrailer. Build the cuts on the filmstrip, adjust duration and speed, write your phrases and add music. If you want, the robot cleans the dead time and signs the video. Then you just export. Who is it for? For anyone who ships apps and wants a professional-looking trailer and screenshots, with no computer, no expensive software, and no video editing experience needed. Why AppTrailer? Because it handles the boring part: the format, the framing and the finish. You focus on showing your app at its best, and the rest comes out ready to submit.

This one is about the look. Three effects to draw over your video, and they stack: Take On Me: the contour redrawn frame by frame, straight from the a-ha video. New Scribbles slider included. Draw Effect: the whole shot synthesized in pencil, stroke by stroke on paper. Runs on the GPU, so exports that took 7 minutes now draw in under 30 seconds. Neon: only the outline, glowing like a sign, with a Treatment that takes the whole scene into neon colors. Plus paper textures and blend modes behind each cut. Reveal: a line slides across the cut showing the before on one side and the after on the other. The screenshot editor got its own Reveal too, with a draggable line and another image behind your art. Also new: Freeze at end: the cut plays and the last frame holds as long as you choose. Music Delay: the video opens in silence and the track comes in later, with the fade in. On iPad and Mac, FX, Adjust, Reveal and Music are movable windows now: drag the handle and park them anywhere. Screenshots: official Apple bezels (iPad Pro 13 inch with the Pencil), a dashed outline showing what you tapped, and a menu on each thumb with Change image from the camera roll or Files. The robot's Loop toggle is reversible: turn it off and the video goes back to how it was. Exact duration adjusts finer, scaling speeds or trims proportionally across all cuts. Fixes: text outline spikes on sharp corners, shadow with the band on, music fade out in the exported video, and a crash deleting a cut from its own settings. Maximum effort!
