## What is Corn Stack?

Corn Stack is the ultimate privacy-first portfolio tracker and calculator. 
And when we say portfolio, we mean strictly Bitcoin-only! 
We eliminate the noise and focus solely on managing your stacked sats.

Built by a Bitcoiner for Bitcoiners, Corn Stack protects your Bitcoin data. 
Your portfolio is stored securely and exclusively on your device using Apple's local database. 
There is no account creation, no cloud syncing, and absolutely no tracking.

• Live Market Data: Stay on top of the market with the latest price data supported across 38 global fiat currencies.
• Two-Way Calculator: Instantly and accurately calculate conversions between your local fiat currency, BTC, and Sats in both directions.
• Historical Charts: Visualize Bitcoin's macroeconomic trends with high-fidelity daily price charts to help keep your time preference low.
• Always Accessible: Whether you are on a flight or out of cell range, offline caching ensures your portfolio, calculator, and the last fetched market prices are always available.
• Node connectivity: Retrieve on-chain and lightning wallet balances using your own node.

Stack your sats securely, and protect your life and time.


## Version history (last 5 releases)

### 2.3 — 2026-08-03

Reliability and polish.

• Clearer watch-only sync progress (Preparing / Syncing / Applying / Saving)
• More headroom before deep-wallet sync times out on personal Electrum
• Settings version display and general stability improvements

### 2.2 — 2026-08-01

More reliable watch-only sync and smoother device upgrades.

• Watch-only balances re-sync after iPhone restore when xpubs are saved in the app
• Faster sync for deep on-chain wallets (smarter Electrum batching)
• Clearer sync status (applying / saving — not stuck at 100% while still working)
• Lightning node IP is restored with your backup; re-enter the macaroon after a new phone (by design)
• Safer upgrades: existing data is preserved; app recovers gracefully if the local store is unreadable
• Stability and UX polish for node settings and full rescan

### 2.1 — 2026-04-17

To utilize the self-hosted features, you will need a personal server (such as Umbrel) running:
* Bitcoin Node & Electrs (for on-chain data)
* Lightning Node (if using Lightning)

Keep stacking, keep verifying!
