User beware- I am a long time user that HAD been very happy with this app (tracked my data in it religiously, recommended to friends, etc). However I just had to replace my phone and because I was using the free version, wink pass will not restore my data. As recently as a few months ago (when I had upgraded my phone) I was able to restore data. Unless you buy a full app, wink pass will block your data. This is very upsetting to someone trying to conceive. There are many similar apps, so I will just use a new one- barrier to switch was removed- thanks wink pass. Many ads in free version (ad revenue you got from my usage over the years!).
