Challenge Log
Start a challenge. Capture the journey. Share the change.
Run a 30, 100 or 365-day transformation challenge. A ghost overlay lines up every photo with your very first shot, so Day 1 and today always match frame for frame. Watch your timeline build itself, then export a 9:16 video ready for Reels, TikTok and Shorts.
Why Challenge Log
- Ghost overlay camera — every new photo lines up with the first one, automatically.
- Streaks without shame — Day / Week / Entry progress and milestones, and never a "you failed" message.
- Automatic timeline — every capture sorts itself, no manual organizing.
- 5 video templates — Classic, Before → After, Milestones, Fast and Smooth, with curated music or none at all.
- 1080×1920 export — ready to post the moment it renders.
- Local-first — your photos stay on your device; no account required.
Made for any transformation
Body & fitness, weight loss, hair & beard growth, skin, drawing & art progress, plant growth, baby growth, room makeovers, DIY and renovation — if it changes over time, Challenge Log can capture it.
