4 stars: Its not bad to keep track, unfortunately its not all quite there for instance... when you are in the app and go back out the icon badge will not dissapear and starts a timer of how long you have had your retainer out in which you have to completely shut down the app and clear notifications to get rid of for the timer to stop. I find this only happens on tray change days.
4 stars: Invisalign app is effective. The product itself is great...three weeks in to mine.
4 stars: Good app but having to use a password everytime for this \
3 stars: Timer is annoying. It would be nice for the app to keep the timer going but not in my notification area. It's annoying for me. There should be an option to be able to hide it. If it's going to be there, it might as well have an option to pause or start timer whenever I take off braces or put then back on.
3 stars: Great idea, however only works sometimes for keeping record of non-wear time. It will carry over for days and not reset. It's good for creating a smile video, and reminding you to swap out. I dont think its a worthwhile app if you just set a reminder for your days to change and take a photo your self.
3 stars: Great app... when it works. Half the time I can't even get it to load, it constantly crashes. I've tried it on multiple different devices, it's very . They also need to improve the ability to save your progress pictures / videos. The format it automatically saves the video in isn't able to be opened...
