FormLapse

Just snap your body each day; it auto-aligns into a smooth time-lapse of your change. Fully on-device, nothing leaves your phone.

FormLapse turns a quick daily body photo into a smooth, auto-aligned time-lapse of your transformation.

■ Build the habit Photos stack up on a calendar. Bulk-import past photos, and a gentle daily reminder with a streak keeps you going.

■ Weight, together Log your weight to see the trend, and overlay your weight progress or an "N days / +-Y kg" summary on the time-lapse.

■ All on device Photos and weight stay on your device and nothing is sent anywhere. Blur faces to share with confidence.
