I've been using this since launch. It works great, you can see balances of each of your wallets, as well as the totals and the fiat equivalents. Sometimes it updates a bit laggy if your phone puts the app to sleep, but no big deal, still very useful. UI/UX could use some work, but it's good enough. No real risk too which is great (except the possible loss of privacy since Samurai will be able to see all your transactions/balances since you shared the xpubs - but that happens with any watch-only wallet). 5 stars.

Very convenient to track cold wallets, but keeps "forgetting" my addresses, which makes the whole thing unusable.

This app shows a positive balance for an empty UTXO. All transactions sent from my wallet show as sent, except the last one still shows a balance that is no longer there. It also will show 0 balance on valid OTXOs for very old transactions. And the fiat conversion is always wrong, says BTC is 7400 right now instead off the real 6800. The values seem to lag for weeks. This app is a good idea that is terribly implemented. I would have never released this garbage with my name on it.
