User reviews

Helpful and fun!

I love this app. It’s simple to use and provides interesting perspectives on the weight loss process for me. it’s always fun to see the progress I’m making.

Doesn’t work

Won’t let me save data. So useless.

Journey towards 100lbs!

I’m just trying to get my head around the fact that the DCR doesn’t go to 52 weeks or longer.
It’s been a good place to start as I have a few different apps I use for my journey & this was my first one & I still use it everyday. I would like to see improvements on the main graph that shows your progress & that’s about it for me.
Thanks for a stable platform for me to use.
UPDATE: The new version is not inspiring me what happened to the color it’s like walking into a clean room (to light & lacking color.) also see no change to the DCR or the main chart and I’ve been using it so long that my data is running off the background (don’t see any reason to continue.). Please make changes to keep me here!

Couldn’t add my custom dose

I currently split dose my 7.5 mounjaro to 3.75 every 3.5 days. The app settings say you can add custom dose amounts but it wouldn’t let me add it, making me unable to use the app.

I also wish it was possible to download the app to android as well, so I could actually use it on my phone not just my ipad…. It severely limits my potential interaction with the app.

Response from developer

Hello, Glad to hear you have enjoyed using the app ever week for a year! It would be great if you message us about the Data Completion Rate (DCR) value that looks odd (support@weighttrekker.com), so we can investigate. Also, I would be happy to hear your ideas about how to improve the main graph. Best wishes, Al
