### 1/5 — App doesn’t open

*2022-01-22, version 1.1*

I’ve downloaded/reinstalled and deleted the app multiple times and it will not load on my iPhone. I’ve also recelntly upgraded iPhones and it still won’t work. Very disappointing since it offers more privacy than CoinTracker

### 1/5 — Doesn’t even open

*2021-12-02, version 1.1*

Downloaded and the app refuses to open. Waste.

### 4/5 — Not bad

*2019-05-06, version 1.1*

Not bad but i rate 4 star because there is no notifications when i receive money.

### 3/5 — Great design, but needs more features!

*2018-09-16, version 1.1*

The app has a great design that is very sleek and modern! However, I wish there were a couple more features:
- An option to show the exact BTC balance instead of rounding up (for example, 0.01234567 instead of 0.012).
- An option to show fiat exchange rate with BTC amount.
- App notifications/email notifications for when the app detects that you have received Bitcoin.
- A iOS widget to display balances.

Overall, the app is still new and I’m sure the developer will eventually add more features, but it is a great concept so far!

Edit: I don’t believe the developer is consistently updating this app, which made me take off a star. The app on iPad only supports portrait view and there’s an excessive waste of space.

### 3/5 — Works great

*2018-08-19, version 1.1*

Only missing push notifications for when I receive a transaction (why I rated 4 stars). 5 stars when that feature is added! Thanks for no ads.
Edit: doesn’t update addresses in a timely manner...dropped off another star.
