1. 2+yrs since update, new version has been in testing for a VERY long time.Great app to watch Trezor bitcoin balance, if only it did not require uninstall & reinstall every couple of days.

2. Would be nice if there was a way to sync UTXO labels with Samourai / electrumDO NOT DOWNLOAD THIS OR ANY OF THESE GUYS WALLETS!!! THEY STOLEN THE BITCOIN OUT OF MINE!!! I have also report their app (Samouri Wallet) to Google (Nothing done about it) where you can't review it as they still have it under "Early access" so your reviews go straight to them instead of the public eye.

3. 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).

4. I would have never released this garbage with my name on it.Tried it with Trezor wallet - got some strange value that doesn't match actual or received balance.

5. All transactions sent from my wallet show as sent, except the last one still shows a balance that is no longer there.

6. It works great, you can see balances of each of your wallets, as well as the totals and the fiat equivalents.

7. I expect to get the option tapping on holding on it but nothing happens.Sentinel makes tracking my wallets easy and rather enjoyable.

8. 5 stars.This app shows a positive balance for an empty UTXO.

9. It also will show 0 balance on valid OTXOs for very old transactions.

10. STAY WELL AWAY FROM THEM, ABSOLUTE SCAMMERS!!!!Normally this is a good enough app but since this last update the app won't even start.

11. It's not perfect, but no other dev out there is doing things purely for the sake of bitcoin these days.
