Quite satisfied with the app. Seems secure enough, while at the same time being convenient. I have a few complaints, though: the interface can be a bit sluggish at times, and the app sometimes brings up a notification with a loading bar that does nothing, and won't go away until I remove it.

New email notifications stop working after a while. I have to turn the apps notifications off and back on to get them working again. Notifications are still in 24h instead of 12h. The zoom capabilities are poor. I have to double tap to zoom but it barely zooms. This is a problem because QR codes or any scannable barcodes are to small to be scanned.

Thanks for your feedback. We will look into this as we continuously improve the app. The latest update gave you offline mode with the Android app, meaning you are now able to read your emails and calendar events even when offline! :)

A little sluggish and a little non-intuitive when deleting emails. Nonetheless, it has almost all the capabilities as the desktop browser equivalent. My issues are with the notification service. I will sometimes get push notifications for new emails, even after I open and read the emails. Doesn't matter if I rad them via the app or desktop site. Also, I am not a fan of the way emails are viewed. There is no zoom capability and the way it goes to the next email after deleting an email. Otherwise, this is still a great alternative to most email providers.

Thanks for your feedback and the bug report. We've just fixed a notification issue, please check whether this improves with the next version. Zooming is possible with a double-tap.
