Nunchuk Bitcoin Wallet earns a solid 9.0 stars for its masterful balance of security and usability in the crypto wallet space. First impression & onboarding: A lean 15MB download, it skips unnecessary sign-ups, requiring only a seed phrase backup—GDPR-compliant and refreshingly transparent. Core functionality & daily use: Executes Bitcoin transactions with military-grade multisig, offline signing support, and Lightning Network integration. Syncs reliably across devices; CPU usage stays negligible during operations. Design & UX: Spartan yet functional; clear navigation without clutter. Dark mode respects battery life, though accessibility options could be expanded. Privacy & data handling: Impeccable. No third-party tracking, local data storage only, and easy account deletion. Open-source codebase invites scrutiny. Monetization: Free, with optional donations. No hidden fees or aggressive upsells—a rare ethical stance in finance apps. Battery, storage, and system impact: Minimal footprint; background processes are strictly limited. Standout strengths: Unrivaled security features, privacy focus, and developer transparency. Overall verdict + score: Best-in-class for security-conscious users. A permanent fixture for those prioritizing privacy. Power users and long-term holders, keep it. Casuals might find it overkill.

I installed this app added three keys, started making a wallet, then noticed the menu item that I could use to login, and they recommended for a better experience that I do in fact log in.I did that, and boom, all my keys were lost. Apparently the app doesn’t realize that a new user might create keys, then log in for the first time. and apparently, when you login, that identity supersedes any implied identity created when you make keys without logging in.So at this point, I’m just wondering: If right out of the gate I get sent back like that, is it worth putting more time in?

Intermediate Bitcoiner here and using Nunchuck as the watch only wallet for my Coldcard Mk4. All working smoothly and giving my way more optionality than my previous set up w Ledger. Signing transactions w NFC now and sleeping like a baby. Thanks for maintaining this app!
