Lapsly: Photo Timelapse Maker

Got hundreds of photos taken a few seconds apart? Lapsly turns them into a smooth video.

Pick photos straight from your gallery. Select whole rows with one swipe: along a row, then down the edge. Or select the whole day with one tap. Frames are always ordered by the time each photo was taken.

Then set the pace. Choose the video length or photos per second, and 24, 30 or 60 fps. Lapsly tells you right away whether the motion will be smooth and how many photos a longer video needs.

Fix the picture without leaving the app. Crop to 16:9, 9:16, 1:1, 4:5 or 21:9 with zoom, rotate and flip, then adjust exposure, contrast, saturation, warmth and tint. The preview keeps playing and shows every change as you make it. Photos in different shapes are cropped to the frame, never stretched.

Sound is covered too. The effects are generated by the app, so they are free to use anywhere, YouTube included: whoosh in and out, an end chime, a shutter click on the frames, and a tone that glides in pitch across the whole video, for example from 40 to 500 Hz.

The finished video is saved to Movies/Lapsly in H.264 at 1080p, ready to watch or share.

Great for clouds, sunsets, city traffic, growing plants, renovations and 3D printing.

Privacy: Lapsly has no internet access, no ads and no analytics. Your photos and videos never leave your phone.

Lapsly Pro is a one-time purchase, no subscription. It unlocks 1440p and 4K export, H.265, ready-made filters, more sound effects (waves, crickets, city, heartbeat, clockwork, rain, wind, projector, vinyl and more) and your own music from your phone. Everything else is free.

For long photo sessions we also recommend ScreenOff: a black screen that keeps the display dark while your camera keeps shooting.
