So useless. ### 3/5 — Journey towards 100lbs! *2025-10-31, version 2.7.1* 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! ### 2/5 — Couldn’t add my custom dose *2025-10-12, version 2.5.1* 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. ### 3/5 — Journey towards 100lbs! *2025-10-02* 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. **Developer response:** 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 ### 5/5 — Great App *2025-08-15, version 2.5.1* Great app but disappointing that you have to keep the two made up profiles of Jill & Jack. Would be much better if you could edit them out. ### 4/5 — A few extra trackers would make this perfect *2025-07-30, version 2.4.1* Adding waist, hips and chest measurements would make this great! Currently I'm adding it in notes but tracking it would help with motivation Otherwise, it's a great free app ### 5/5 — Simple *2025-05-16, version 2.4.1* Good tracker, free version is good!! ### 5/5 — Simple *2025-05-10* Good tracker, free version is good **Developer response:** Thank you Kita for the great review. Much appreciated! Best wishes, Al ### 5/5 — Thank You! *2025-04-11, version 2.4.1* Great app. Love that you can view predictor data for customizable periods to encourage continued progress towards one’s goals. ## Frequently asked questions about Weight Trekker ### What does the Weight Trekker app do?
