I re-do the whole information fill out process, only to be kicked out once again when I refuse to buy the stupid membership. Money hungry app, I’m finding something else. ### 3/5 — Update worsened interface - no interactive graph anymore *2026-06-22, version 2.38* I’ve used this app for a number of years and about a year ago switched from Android to Apple. I’ve noticed in the last few months that the graph that tracks your weight records is no longer interactive. So if I slide my finger along the graph line it doesn’t tell me at any data point what my weight entry was. Instead I now have to scroll back through my entries in the list to find a weight point. In fact the graph now just looks like a drawing. I found the interactive graph really useful for looking at my weight trends and seeing what my particular weight was at a particular time and then being able to determine if there as a specific event or life stage that may have been impacting that weigh in. The loss of this functionality has made me look for alternative apps to switch to as a result. I’m super disappointed and up until that change I would’ve given the app 5/5. I hope this aspect of UI can be reinstated soon. ### 1/5 — I don’t like the new app update @all. *2026-06-21, version 2.38* Because now I have to pay to put in my weight loss. ### 1/5 — Гении блин *2026-06-12* Пользовалась несколько лет, нужна была одна функция - фиксация веса. Теперь оказываете без платной подписки я не могу это делать каждый день как раньше, теперь есть ограничение. Ребята, все что от вас мне было надо это чтобы ваше приложение запоминало дата - вес и рисовало график на основе этого, такое может много кто. Даже блин Эксель файл. Ладно, я потрачу время что бы перенести данные от вас, потому что реально за базовую функцию которая не работает бесплатно платить я не готова **Developer response:** Извините за причиненные неудобства. В сложной разработке приложений могут возникать проблемы. Пожалуйста, обновите приложение до последней версии. Если проблема не будет решена, дайте нам знать. Спасибо за ваше понимание. С уважением, Thomas ### 1/5 — Обман *2026-06-11* Встроенные покупки ### 3/5 — Entering weight *2026-06-09, version 2.38* Sorry I have to leave the app since there's a charge to now enter your weight daily. This is the only apo I have used for weight tracker only since 2017. Thanks for the past experience, but it's pointless now just to pay to enter my weight! ### 2/5 — I hate the changes *2026-06-01, version 2.38* Ive been using this app since 2018, i absolutely loved it. I’ve just had the update and everything has completely changed, but unfortunately i hate it. I hate the new layout compared to the one before, i miss the old BMI tracker and the old colours. It was so vibrant before, now its so dull. It also now feels like its heavily pushing you to pay for PRO on most tabs, which i wouldnt have an issue with if it was not as bland and different as it is now. The last thing i hate is there is now a streak section which is promoting daily weigh ins which is very unhealthy for people suffering with unhealthy weight obsessions, as its encouraging you to weigh yourself daily with it being on the home page. I think i’ll be looking for a new weight tracker now 🙁 absolutely gutted i’ll have to lose or re-upload my progress elsewhere Anyway, thank you for the app from 2018 up until now. It truly was great, and i appreciate how it was for so long🩵 ### 5/5 — Gute App zur Gewichtskontrolle *2026-05-27* Ich suchte eine App, wo ich mein Gewichtsverlauf beim Abnehmen kontrollieren kann. Bin von dieser App begeistert. Einmal kaufen und gut. Keine ständigen Extrakosten oder nervige Werbung. Das Gewicht eintragen der Verlauf ist numerisch und als Diagramm sichtbar. Er aktuelle BMI wird direkt ermittelt. Die Tipps sind nicht aufdringlich, eher dezent. Mir gefällt die App sehr gut und kann sie nur empfehlen. Keine Kalorien oder ähnliches zählen. ## Frequently asked questions about BMI Calculator + Weight Loss ### What does this app do?
