## What is SIGBRO?

SIGBRO keeps Ardor accounts safe in the Apple Keychain. 

With SIGBRO you can auth and sign in to web UI's that have SIGBRO Auth* integrated, and see your transaction history, NFTs, and token balances. SIGBRO supports local signing of transactions on the Ardor blockchain platform, from multiple accounts, and shows the user the correct tx details before letting the user approve them, so users avoid getting tricked into signing bad transactions if they end up on a phishing website. 

SIGBRO can notify the user about transactions in accounts they monitor. Users can subscribe to alerts about incoming/outgoing transactions, forging or bundling rewards, read encrypted messages (the app decrypts them, if the user has reading-rights), and approve transactions in accounts under Account Control. 

*) SIGBRO Auth is a passwordless login method. You can contact us for specs and learn how to integrate it into your Ardor app or any other web UI.

### 5/5 — Simple to Use

*2021-10-25*

The app is simple to use and gets the job done in terms of viewing your assets at high level.

I would like some UI and usability improvements, should the developer decide to continue developing this app.

1) Add a trend chart in the home screen to show coins’ value in USD (your portfolio value or just a trend from CoinMarketCap.

2) On the home screen, add small box (maybe 200 x 300 pixels) with logo and short description. Make the box sliding left/right as more projects are added. When user clicks on the box, open a new page to show more details. I was a huge fan of Nxter Magazine when you were actively publishing articles! Maybe you can pickup that pencil one more time?

3) I don’t see the ability to send/receive coins. Not sure if this is in development or not part of the scope for this app.

4) Wallet > Wallet > Coin (ardor) > Transaction history
Formatting on this page doesn’t look right on iPhone 12 max pro. Also, top and bottom menu sees odd and could use some UI/UX designing, if you are open to it.

5) What’s the difference between Alert and Messages? I have both of these empty right now, so maybe you can further add features, or maybe my app will populate once i do something within my account, like send/receive coins or purchase NFT.
