User reviews

RIP

Thank you for helping me that one time when no other app was able to. Or maybe signal was, but still.

Bad on notification

You don't even know you have a message unless you actively check the app. There's no badge or anything unless you happen to be staring at your screen when it comes through. It's pointless to send feedback to the developers because they don't follow-up. This app hasn't even been updated in over 2 years!!

Appreciate that they tried, but

Was the interface written and never tested? Or was the intent that it not work? Perhaps it secretly implants a virus or trojan??? Tried to invite a new person to get the app and use it with me. Couldn’t write the message because the text composing box was off-screen in both the vertical and the horizontal orientations. Even though I could type stuff in, I couldn’t send a message because the SEND button was also below the bottom edge of the screen. If an apparently reputable company such as Spideroak makes an app with such glaring blunders (as basic unusability) you have to wonder about their motivations. Hey, y’all, listening? Fix it and get back to me, k? It’s: 2020.06.08 FFS! How could you do so badly? Who would trust anything else you do — I would not....

UX is very aweful

Newer iPhones screen sizes are not supported, the app looks outdated.

iPhone X Support

The screen isn't designed for the iPhone X line of phones.

Not really a fan of the UI either, but I can't begin to see the usefulness when the app is letterboxed.
