WTNS: track change over time

A few of the journeys worth keeping

If it changes,
you can witness it.

WTNS can document anything that changes visually. With ghost overlay keeping every shot aligned, at whatever interval suits you, for as long as the change takes, here's the kind of transformation you could capture. A few more ideas: a scar healing, a city skyline being built, a bonsai you're shaping, your hair growing out, a leather bag wearing in.

Skin · 84 days

Watch skin clarity turn a corner.

Track a breakout back to calm with a consistent, well-lit frame, then log clarity, mood, and what you changed alongside each shot so you can see what actually worked.

Plant · 1 year

A cactus grows too slowly to notice, until now.

Snap the same frame once a month and the year compresses into a few seconds. Log height and waterings so growth spurts line up with what you did.

The metric that photos can't show

Track how you feel, not just how you look.

Use a cream for six months and someone asks if it worked, and you honestly can't remember how bad it was at the start. A graph shows you. Track any metric you like, from hundreds of templates or one you invent yourself, and watch it move.

Self-consciousness Happiness

Self-consciousness started high and happiness low. Nine months on, with the real dips and setbacks along the way, the lines have crossed. That's the story the photos alone can't tell you.

Built for the long game

Everything you need to document change honestly.

The photo is only half the story. WTNS keeps the numbers, the feelings, and the context right beside it.

Ghost overlay technology

Line up your shot with a semi-transparent overlay of your last photo; opacity runs from 0 to 100%, with an optional grid for composition. No more guessing, no more crooked comparisons. It's what makes every before/after land.

Custom metrics

Weight, cost, size, mood, sleep: 30+ presets, or build your own. Photos tell part of the story; metrics capture how you felt and what it took.

Time-lapse playback

Your sequence becomes a video automatically. Adjust speed from 0.5× to 4×, then export and share the whole journey.

Notes on every photo

Leave a note beside any frame: what you changed, what it cost, what threw the numbers off. Context you'll be grateful for later.

Smart reminders

Daily, weekly, or custom intervals with morning, afternoon, or evening preferences. Consistency, without the nagging.

One app, countless journeys
