A sat, short for satoshi, is the smallest unit of Bitcoin. One bitcoin equals 100 million sats. Satchi brings that tiny unit to life as your own little companion.
Tamago is coming soon to iOS. The app will be free and open source. We’re building a native iPhone experience with Apple’s Liquid Glass design. There’s no release date to share just yet.

Your new companion is on the way.
