OpenStrap is free, AGPL-3.0 licensed, and has no company, no subscription, and no revenue behind it. It exists so the wearables people already own keep working without a subscription, with their data staying on their phone.
If it's useful to you and you'd like to chip in, these are the only addresses. There is no other donation channel, no token, and nothing for sale.

Please don't feel obliged. The genuinely valuable contributions are free:
- Open an issue when a number looks wrong. Reports from real devices on real wrists are worth more than money: otherwise the test data is one person's physiology.
- Test a device you own. Oura, Garmin, Pebble, Colmi, Ultrahuman and Mi Band support is being built and needs people with the hardware to check it.
- Tell someone whose wearable is sitting in a drawer.
They don't buy priority, features, or support. This isn't a paid product and turning it into one would defeat the point. What they realistically cover is the Apple Developer Program membership that keeps the TestFlight build alive, test devices (each new wearable needs real hardware before its numbers can be trusted), and coffee.
Nothing is gated behind paying, and nothing ever will be.
