### 5/5 — Great Wallet with enormous potentials

*2021-07-30, version 3.0.3*

This wallet is private and secure, with the potential to sweep clean the crypto market wallet space. You can hold and trade crypto assets from and across multiple blockchains. It allows a novelist user to navigate the ropes of holding and exchanging cryptocurrency‘s in a simple and elegant way. It also makes it hard for you to make mistakes with its unique and savvy user interface.

### 4/5 — Great Wallet - One Missing Feature

*2021-05-08, version 2.2.3*

I love this wallet. It’s very user friendly and offers great access to the other dapps. Unfortunately, I can’t seem to sync my gas generation multiple times. I’d like to sync it often to see how much I generate without having to claim it each time.

### 1/5 — Bug

*2021-04-29, version 2.2.3*

The app gets frozen and doesn’t work on the latest iOS 14.5

### 1/5 — Garbage

*2020-12-14, version 2.0.1*

This app and the new ontology app are garbage

### 2/5 — UI/UX needs work

*2020-09-01, version 1.0.0*

Unclear why the NEO and Ontology wallets are separate. Too much friction to make a wallet. Arbitrary password requirement is odd when the device has built in keychain encryption and can require the device passcode or touch id. Old app was better overall.
