## What is Sato?

Sato is a calm, watch-only bitcoin tracker. See what you've saved without the noise.

Paste a public address and see your balance. No account. No seed phrase. No keys. Sato can only look. It can never move your bitcoin.

WHY SATO

Bitcoin goes up and down in dollars, and most apps make you feel every swing: charts, alerts, red numbers. But bitcoin tends to reward the people who do nothing. Sato is made for that. Open it now and then, see where you stand, close it again.

WHAT YOU CAN DO

- Track several wallets, each with one or more addresses
- Organize by goal, like a house, college, or retirement, with your own icon and color
- See balances in BTC or sats
- Show value in 29 currencies, or hide fiat completely
- See pending amounts separately, so nothing surprises you
- Use Legacy, SegWit, and Taproot addresses

PRIVATE BY DESIGN

No account, no analytics, no servers of our own. Your wallets stay on your phone. Sato only asks public block explorers for balances and a price service for exchange rates. Nothing identifies you, because there's nothing to identify.

SATO PLUS

Sato is free with one wallet. A single one-time purchase — never a subscription — unlocks as many wallets as you like.

## Pricing and in-app purchases

Base price: Free.

**One-time purchases**

| Purchase | Price | Type |

## Version history (last 3 releases)

### 1.2 — 2026-09-25

Face ID lock. Turn it on in Settings and Sato asks for Face ID every time you open it.

Hidden in the app switcher. Your balances blur when you swipe between apps.

Cleaner goals. Goal amounts drop the trailing zeros, so 0.25 BTC shows as 0.25, not 0.25000000.

### 1.1 — 2026-09-25

Goals. Give a wallet a target, like a house or a year off, and watch your stack grow toward it.

Home Screen widgets. Check a wallet's balance or goal progress without opening Sato.

Light theme. Pick Automatic, Light, or Dark in Settings.

Flip to hide. Put your phone face down and your balances disappear. Turn it on in Settings.

iOS 18 support. More iPhones can run Sato now.

Also: a cleaner address card and a friendlier welcome.

### 1.0 — 2026-09-23

No release notes.
