love this app. have been using this for years and it is extremely accurate. docking a star due to the visual design. all theme options are so light/bright. I want darker themes, deep blues, purples black.... the period countdown widget is the best feature, but I wish we could choose different colours for the widget. it's just so pink and bright, it sticks out like a sore thumb on my dark themed home screen.

I don't mind ads I know they need to make money, but I will be uninstalling. I opened the app as usual and the only "open" button I saw was the calendar button. The upper right corner where you click to go to the calendar homepage had the link to the Taco Bell app. To bypass the ad, I clicked "open" which had the picture of the my calendar icon. The mislabeled link opened my Taco Bell app. I had to go back to access my calendar. I'm not comfortable with that. I am uninstalling.

Hi, sorry for the unpleasant experience. Usually, you can click the icon in the upper right corner to close it and enter the app. We understand how this can be frustrating, and we are actively working on improving the display so that users can easily access the calendar. Thanks for your understanding. Hope you'll give us an opportunity to improve.

Had been using this app for years, but now I have to have a Facebook account to access my data. I don't have or want a Facebook account. Now all of my saved info for the past few years is lost due to a needless change. I guess I'll have to find a new tracker. Edit: I am now able to bypass the Sign into Facebook so I can access the app again. Thank you for the quick fix!
