Functional, but Claim button has poor UX


Clicking the claim button has poor user experience (UX). It takes a while for the waiting indicator to display (“Claiming gas this may take a while”). While you are waiting to see the wait message you may find yourself wondering if you actually tapped the Claim button and you may tap it again. After it finally displays and goes away, you see a cryptic alert dialog that says the claim was successful, but it may take a while to show up in your account. Often, in my experience, the app needs to be restarted before you can see your new gas. Sometimes you get strange error messages at this stage. It’s just not ideal UX.

Developer Response

We hear you! Can you try the version 1.5 and let us know how we do with the new claiming UX ?



Response to dev response: on iOS, if offline, the app loses all functionality and displays an error message “uh oh! There is no internet connection” with an emoji. Everything else gray and nothing clickable.

Edit: devs were super responsive and had the issue remedied within a day. Upped rating to 4 stars-good up but still a bit clunky. And I dislike having to be connected to the internet to generate a new wallet. This is an essential security flaw.

App on iPhone and iPad crash while sending a tx. Updated and still having same issue. Cannot send neo or claim gas without crash.

Developer Response

You don't have to be connected to the internet to generate a wallet. Everything is generated offline and your private key never leaves your device. It's securely stored in the keychain.

Beautiful, Incredible


The UI is extraordinarily beautiful and functional. The UX rises to match, with the developers constantly adjusting details to create a wallet unparalleled not just among NEO/ ONT fans, but compared to all wallets, it has no equal. Switcheo is integrated so it seems native and perfectly compatible with O3. In time, this wallet boasts such supremacy that you may find yourself breathing O3 as often as O2! Thank you, developers!

Developer Response

Wow! thanks for your positive feedback. Go O3!
