It’s simple and helps me visualize my progress. HOWEVER I’ve lost my data TWICE because of the goddamn updates, and there’s no way to get it back. So about a year of tracking down the drain. Very, very disappointing. ### 4/5 — No funciona la aplicación *2020-01-17, version 2.9* He pagado y no puedo utilizarla ### 1/5 — Not working for IPhone X *2020-01-01, version 2.9* As if an event was needed for the app to work under IOS . Without events ... not working ### 1/5 — Ne s’ouvre pas *2019-12-09* L’application ne s’ouvre pas J’ai désinstallé et réinstallé , redémarrer le téléphone... pas de solution. Dommage ### 1/5 — 결제했는데 오류나네요 *2019-11-02, version 2.9* 결제를 했는데 error.iap.unknown 이란 문구가 뜨네요 확인좀 해주세요 ### 1/5 — xr 인데 어플이안켜져요 *2019-11-01, version 2.9* 어떻게합니까 이거??? ### 1/5 — No actualiza *2019-10-25, version 2.9* La app es funcional y cumple, pero no actualiza version ajustandose al nuevo ios de iphone y no funciona en ios 13. Una pena ### 1/5 — 업데이트 해주세요 *2019-10-14, version 2.9* 아이폰 소프트웨어 업데이트 이후 먹히지 않아요 확인해주세요 ### 3/5 — Ibis *2019-10-09* L’application est parfaite seul bémol c’est le payement. Je m’explique; Je veux bien à la rigueur payé une seule fois. Mais payer par prélèvement chaque mois NON. Je veux bien vous aidez, mais je ne vais pas me couler financièrement non plus ### 1/5 — No funciona *2019-10-05, version 2.9* Dejó de funcionar. Ya no abre la aplicación ### 4/5 — ios13 업데이트 이후로 실행되지 않습니다 *2019-10-05, version 2.9* 어제 ios13로 업데이트를 했는데 그 이후로 실행이 되지 않습니다. 조치 부탁드립니다. ### 1/5 — No abre *2019-09-30, version 2.9* Intento abrir la app y se cierra automáticamente al segundo. ### 1/5 — No funciona *2019-09-28, version 2.9* Que es lo qué pasa ? En el iPhone XR cierra y no me abre más ### 2/5 — Não funcion *2019-09-24, version 2.9* Após atualização para IOS 13 o App parou de funcionar ### 1/5 — Desaparecio *2019-04-11, version 2.9* En mi iphone XR no me aparece el peso guardado ### 1/5 — The app does not track correctly and support team does not help. *2019-02-28* Although I have been using the app daily, my progress has not been stored correctly and my measurement inputs have not been able to be updated properly. I have reached out to support in various way, which were all very difficult to find. I’ve even left support tickets but they are just continually deleted. If you are serious about your nutritional and health / weight goals, this is not the app I would recommend. I needed to provide data to a dr for health reasons and serious health concerns and this was very unhelpful and disappointing. ## Most critical reviews (10 lowest-rated) ### 1/5 — Por tonto la compre *2024-11-28, version 4.0* No gasten ni un peso no tiene ninguna utilidad mas que tu peso es todo, hay otras mucho mejores. ### 1/5 — 一直闪退 *2024-07-25* 一直在logo页面加载不进去 重启了这样，删除重装也一样 ### 1/5 — nur kurze freude *2021-10-01* zeitlich erster Datensatz lässt sich nicht mehr löschen. Um die Daten zu löschen habe ich dann die App gelöscht und neuninstalliert. Danach öffnet sich die App und stürzt ab. Leider unbrauchbar. ### 1/5 — 👎🏻 *2021-01-24, version 4.0* No la descarguen, no pierdan su tiempo, solo sirve para llevar anotaciones de tu peso, de hay en más no tiene otra utilidad, ni para llevar estadísticos, ya que te pide suscripción, mejor anotar eso en el block de notas, es mejor ### 1/5 — After update all data lost *2020-11-24, version 4.0* I use Slim for several years now and have a subscription. After yesterday’s update, all my previous data are gone! That’s a real shame, to the least and to say it politely. Would be great if this can be fixed and if the previous data can be recovered! Just checked Shortcuts to enter my weight and to register it, the date and time in the Health app, which works fine, as well. ### 1/5 — Schade Abomodell 👎🏻 *2020-09-10* Die App scheint richtig gut zu sein. Übersichtliches Interface. Gefällt mir sehr gut. Leider ist auch diese App nur im Abomodell zu haben. Gute Apps kaufe ich gerne - zu Einmalpreis. Auch für große Versionssprünge mit echtem Mehrwert bin ich gerne bereit zu bezahlen. Schade, App wieder deinstalliert. **Developer response:** Vielen Dank für Deine Bewertung. Slim bietet neben einem Abomodell auch eine Freischaltung aller bestehender Funktionen und zukünftiger Updates zu einem einmaligen Kaufpreis an. Schau doch nochmal in die App und vergleiche die verschiedenen Modelle ;) ### 1/5 — 폰바꾸고 *2020-06-12, version 3.2.1* 그 전엔 연동이 잘 되었는데 폰바꾸고 연동이 안되네요ㅠㅠ 해결방법좀 ### 1/5 — App was given a lobotomy yesterday. *2020-05-08* I have used the Slim app for years, and even though it would not reload saved data from years of use when I bought a new phone a few years ago, I continued using it because it was simple to use, the data was easily interpreted and it was very easy to add data to. Well, all that has changed! I went to add a new weight number this morning and encountered a whole load of problems. First, the dashboard was unrecognizable. Well, I figured even though it was pretty horrible, I might get used to it. Second everything was in metric which after hunting around, I was able to change easily enough. But the two other issues I encountered, basically have me looking for a new app for the purpose of tracking my weight. First, the target weight was NOT what I set some years ago, and have steadily made progress towards. Instead, it had a target weight over 250 HIGHER than my current weight. Okay, so I change it to my long established target weight and save it. Except, it did not change. And after many, many attempts to correct it, no luck! Then came problem two. I added my new weight, now just two pounds exactly from my goal weight this morning, and even though I added the weight exactly to the tenth of a pound, what it recorded was 555.6 pounds. I made many, many more attempts to add and save the correct weight of 252.0 lbs. only to have the same wrong weight of 555.6 lbs be displayed. Oh, and the very convenient scrolling bar that allowed you to just scroll to your weight by tenths of a pound, now is a keyboard where you have to enter the digits manually - another strike against using this app anymore. I even tried reloading the updated app. Nothing changed or was corrected. I searched for a means of contacting the developers directly to alert them to the issues created by their changes, but nowhere in the app was there a means to do so and the help section drops you into an essentially useless FAQ and a search bar that couldn’t fine even the simplest answer regarding resetting the goal weight. BTW, the pictures shown of what the app is supposed to look like are the way it looked BEFORE the developers destroyed it. I will check back to see if they correct these problems with their now unusable app, but will now have to waste time searching through the dozens and dozens of other weight tracking apps for one that will do what this one used to do. Too bad! **Developer response:** Thank you for your review. Unfortunately, there must be an issue with unit conversion (i.e. lbs to kg) when entering a weight and target weight. We are working to resolve these issues. The scroll interface for entering your weight was replaced with keyboard input due to customer feedback. ### 1/5 — Error en la aplicación *2020-01-23, version 2.9* Descargue la aplicación pero no me deja entrar, solo parpadea. ### 1/5 — No prende *2020-01-05, version 2.9* No funciona la aplicación! ## Most praised reviews (10 highest-rated) ### 5/5 — Kann ich nur weiter empfehlen *2025-05-26* Ich habe mit der App 20 kg abgenommen ohne das mir ständig abos vorgeschlagen wurden sehr sehr gut 👍👍 ### 5/5 — Gewicht *2024-01-24* Diese App hat mie sehr geholfen beim abnehmen ### 5/5 — 이번업데이트 맘에 들어요 *2020-05-05, version 3.0* 한동안 안 켜지더니 !! 이 앱 최고 깔끔하고 최고 좋아요 ### 5/5 — 굿굿 관리 *2019-10-15, version 2.9* 이 어플로 체중관리잘하고있어요. ### 5/5 — 좋아요 *2018-06-11, version 2.9* 간편하고 좋네요 ### 5/5 — 🙃🙃🙃 *2017-08-19* Приложение очень классное, худеть с ним очень удобно, отслеживать вес ### 5/5 — 깔끔해요! *2017-08-06, version 2.7* 가장 기본적인 그래프형식이라 눈에 잘들어와요:) 저는 잘쓰고있네요 :) ### 5/5 — Muy buena app pero le hace falta notificaciones *2017-06-27, version 2.7* La uso en iPhone y me parece muy buena app, estaría bien si enviará una notificación como recordatorio ### 5/5 — 구입항목 *2016-11-05, version 2.5* 구매 리스트에서 삭제 부탁드립니다 ### 5/5 — Does what it says it does *2016-10-10* Great app for weight tracking, especially if you're a chart geek like me.
