WatchOnly
Read full descriptionHide full description
WatchOnly is a local-first, read-only Bitcoin dashboard for your existing self-custody setup. Import a public descriptor or xpub to view balances, activity, confirmations and UTXOs across your wallets. Review address reuse, connection exposure and other practical privacy signals, then choose the blockchain source that fits your setup: your own server, a Tor-proxied public source or a direct public source. Your wallet data stays on your device in protected local storage. WatchOnly has no accounts, ads, analytics, cloud sync or WatchOnly-operated backend. It never asks for or stores recovery phrases, private keys, wallet PINs or passphrases. WatchOnly cannot create, sign or broadcast transactions. It complements a signing wallet and a properly maintained recovery backup; it does not replace either one and does not provide financial advice.

Verdict
The clearest difference is in-app purchases: WatchOnly at none against OpenChart's 2. WatchOnly also leads on iOS requirement (14.0 vs 17.0). OpenChart's advantage is update cadence (every 8 days vs every 6 weeks). On price, ads and device support there is nothing between them.
