Love it !

Love it ! Love the charts, love the daily weight list, love the sound effects that congratulate you when you loose weight. Waaaay better than any of the other weight apps I have tried. I do have one suggestion, though. I would really like for there to be an additional "note" column on the Protocol page. There would be plenty of space for another column between the date and the weight column. Additional information could be recorded there, like 'Thanksgiving weekend', 'annual Christmas party', 'sick with flu', 'ran five miles yesterday', 'fasting for medical tests' ......... it could be a place to record explanations for a sudden increase or decrease in weight. You could even write motivational notes here to encourage yourself to keep trying or to keep it up. With this addition, the app would be perfect ! I am hoping for an update that includes this suggestion. :)

Developer corrected update issues to my satisfaction. I initially had difficulty contacting support via their website because the captcha wouldn’t load. I realised that the reason it wouldn’t load is because I never verified the email associated with my account. Once I did that the captcha loaded and I was able to contact customer support. They got back to me within two hours. I was informed that they had a fix and were waiting for approval from Apple to load it to the App Store. When I logged into the app this morning all my historical data was correct.

(Almost) perfectly simple

Great for monitoring weight changes and conversion to BMI. It keeps things very simple for you. Slight issues that do not attract much as I will continue to use it. It is clearly metric oriented. Inches do go to 11 now, but weight progression says kilograms even though the number represents pounds. Normal BMI is 18.5 to <25, but they seem to be using actuarial tables possibly as for my age they list normal as 19 to <26. Not an issues as long as you know what is correct for you. Finally when putting in a new weight, the weight spinner is never on the previously recorded weight which would be nice. It always seems one pound higher which I assume they do so you feel some positive reinforcement (so you like using the app?) but again minor and I thank the developers for making their app available.

Excellent Product Great App!

It’s very obvious that a lot of thought went into building this app and I appreciate the developers though process and hard work! Over the last few years, I’ve explored a lot of other weight tracking apps but found them missing certain editing toggles or features that would make my weight loss and management tracking easier, this app has everything that I’ve wanted... I’m delighted with it and definitely have recommend it to my friends, family and others at my gym!🙏
