iPhone + iPad
Document slow change, one aligned photo at a time.
Constant Change is a local-first app for long-term visual records. Start with a reference photo, line up future photos with a ghost or edge overlay, then replay the sequence as a private time-lapse video.
Use a template photo as a ghost or edge guide
Track body progress, plants, kids, construction, and more
Add date, notes, place, and optional measurements
Preview and export MP4 time-lapse videos
Local-first: no account, no server, no tracking
Built for changes that take time
A steady frame makes subtle progress visible.
Keep useful context
Store notes, places, dates, and measurements with each photo. Body weight can be read from HealthKit when you choose.
Adjust without destroying originals
Manual alignment stores transforms separately, so the original captured photos remain available.
Export the result
Replay the sequence, choose speed and transition style, add optional subtitles, and export an MP4 video.
