The previous version was much better. It was much more linear and you can track your progress easily. This version lost linearity and let you just jump right into any sort of training, and broke a lot of its appeal in doing so. If you do follow it, the app does help you to an extent, each person will have a different experience. I have had more success with the previous version than I did with this one. Also, upgrading logs you out and they didn't happen to save my progress from the original which was off putting. The latest update is broken too where the keyboard doesn't go away/no enter key, and progress sometimes doesn't record. This version makes you play the doctors videos every time you start training, you can skip it, but in the previous version, the app already knows you've watched it. You would think that after all of the media attention this app got, that they would improve the app, not make it worse.
