Got my name wrong in the reply, but I clicked on the barbell icon and see my info. Thanks like others I've used the free version for many years (2019) recently they made the free version so difficult to use I did the paid version. No longer can you see past weights in the app, you have to download the data and sort it from there. PDF download starts with the oldest weights first so if you have years of data, scroll, scroll scroll. Paid money now I have to do more work to see my progress

I have been using this app for more than 7 yrs now, but it seems with the new update I may have to change as I am unable to log daily now. I also loved the pre update look, but now... it looks so dull. Sad!! Hi I have changed my phone. When trying to import data it is giving error of access. Access Access to file and storage has been given...can you help? Love you for this...it's corrected, and I could import...thanks a lot...increasing a ⭐. Could retrieve all from 2019😃

Hello, Until last update from April everything was fine in the free version. Now you can't add any new Log Weight. It ends in the home screen every time you try to add new data. Can you fix it ?

It used to work fine until they increasingly started slamming you with more and more ads. And now I can't even enter daily weight records without paying for it. I'm done with this app.

I hate the way the new update looks 😭😭😭 I've been using this app for so many years, and it's one of my favorites but with the new layout it's just not it anymore.
