tldr: the interface is cluttered and slow. The typeface is too small to read. Crashes when re-entering app. Some nice AstroTurf reviews here. I actually used this and heres what I think... A universal app that stores personal data but offers no sync between multiple devices? Sounds like the developers didnt actually use the native SDK. So I should pick one place to use it, and delete the other? The gestures are clearly not native. A swipe should be a swipe, not a delayed request to ask the app the do something. The interface is also pretty, but confusing and non obvious. Too many useless buttons and too much focus on data collection. Constantly hijacks the lock screen. Just waking up, or tired old eyes? Keep moving. This app will drive you bonkers. Sort of ironic that an app made for relaxation makes me so irritated. Consider skipping this until the developers set their standards higher.
