Local-first weight tracking
Track your weight, without the noise.
Saitama is a simple, private weight tracker from Waystone Labs. No accounts, no ads, no feeds — just you, your numbers, and a clear trendline.
Waystone Labs is an independent software studio building small, opinionated consumer apps.
⚖︎ Built to be boring (on purpose).
Saitama doesn’t try to gamify you. It quietly tracks what matters and gets out of your way. The magic is in showing up, not in shiny charts.
Clarity
7-day rolling average
Smooth the noise and focus on the trend, not the random daily spikes.
Privacy
Local-first data
All your entries live on your device. No cloud sync or surprise “backups”.
Future
Goal tracking (soon)
Set target ranges and get gentle nudges when you drift too far from them.
Future
Simple progress exports
Export your data as CSV so you can play with it however you like.

More tools coming
Saitama is our first tool. We’re quietly building more small, opinionated apps.
✨ From the Waystone Labs.
This site will eventually list all our products. For now, Saitama is the only guest.
We’re exploring a small family of focused tools around health and habit-building. When they’re ready, they’ll appear here — same domain, same quiet design.
