Would be nice if the day the dosage is taken could be edited. A few times I’ve had to take my shot on Sunday as opposed to Saturdays. I make a note of it on that week in the app, but it would be nice to be able to edit it. Otherwise, this is a great app and I’m so glad I happened upon it! Definitely still 5 stars, and I’ve recommended it to others as well.

Hello, Thank you for the really positive review! Good news, the new update (v 2.4.0) has a few new improvements, including allowing the user to change the dosing day! Just undergoing testing now. Should be released in 1-2 weeks. Check under 'Customisations' in the Settings when it comes out, and contact us if there are any problems. Best wishes, Al

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!
Developer Response
UPDATE Sorry to hear you do not like the new colors. Please do contact us if you would like to see your DCR fixed, as at the moment I cannot see any fault with it, but with your account details I could check it out. The slider should go to 104 weeks (2 years), so you should be able to see all your 1 year data comfortably (and now you can add more weeks(up to 4 years now) in the Data view). Hope you like the new update (3.0.0 just got released today). 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
Like the app, looking forward to the updates

I like that I can use the app and both my phone and my iPad. I wish that the dose amount could be even more personalized. I will likely use a dose between 5 mg and 7.5 mg but there’s no way to put that in the app. Also, it would be great if we could start the week with your weight on the shot day.
Developer Response
Thank you 2BusyMom for such a great review! Good news on the dose front...the new version (2.0) is going through final testing now, and should be released in 1-2 weeks. It has a bunch of new features, including the ability to customise your dose! Once it is out, drop us a line at the support email address if you have any problems.
Great Analytics and Graphs

Excited to see an app with predictive modeling being developed. Data entry is user friendly. Seeing the progression of the dosage concentration is helpful. As I entered portions of my data and played around with my data set, the app accurately predicted the progression of my weight loss. Would love to see injection site (correlated against side effects) and fatigue (side effect) added to future releases.
Developer Response
Great to hear the app is working well. Good news...the next version of the app should have both injection site and fatigue as optional endpoints that you can track. Hopefully should be released in 4-6 weeks. Good luck on your weight loss journey!
