Track anything that transforms over time, one perfectly aligned photo at a time. Some changes happen slowly; that's exactly why they're worth capturing.
Playing. Drag the slider any time to take over.
A photo shows you that something changed. The number you logged and the note you wrote that week tell you what caused it: the new product, the higher dose, the fortnight you skipped. Say goodbye to placebos.
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.
Start tracking any metric, free on the App Store.
Everything you captured, laid out as a clean document: the photos in order, the date on each one, the metrics you logged and the note you wrote at the time. Hand it to a dentist, a dermatologist, a contractor, or the friend who keeps asking how it's going.
Nothing leaves your iPhone until you choose to send it.

Anything that changes visually counts: the results of your new whitening toothpaste, a hair loss and regrowth journey, a baby bump, or simply the view from your window turning through the seasons. WTNS can witness it all.
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.

No account. No cloud. Just your iPhone.
The photo is only half the story. WTNS keeps the numbers, the feelings, and the context right beside it.
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.
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.
Your sequence becomes a video automatically. Adjust speed from 0.5× to 4×, then export and share the whole journey.
Leave a note beside any frame: what you changed, what it cost, what threw the numbers off. Context you'll be grateful for later.
Daily, weekly, or custom intervals with morning, afternoon, or evening preferences. Consistency, without the nagging.
Your first record and your first five photos are free forever. Don't like it, don't pay. Only ever need five photos? It's yours.
No trial countdown and no card required. Keep it as long as you like.
That's $1.67 a month, a 58% saving against paying monthly.

If it changes visually, WTNS can track it.
