I built Spectator, a free read-only Bitcoin wallet tracker

I was looking for a way to track the value of my Bitcoin. I store my crypto in a hardware wallet, and most apps are full-featured wallets designed for sending transactions. But I just wanted to monitor my investments without exposing my private key.

So I built Spectator, an iOS app where you only need to enter your public wallet address. There's no security risk because it cannot access your Bitcoin at all. It just reads data from the public blockchain. No authentication, no cloud sync, no tracking or other BS.

Features:

• Track multiple wallets
• Home screen widget
• Interactive charts showing gains and losses
• Full transaction history with USD value at time of each transaction

The app is completely free with no ads. This is my first iOS app, so I'd really appreciate any feedback or feature requests!
