Slim helps you keep a healthy weight. Its wrapped in a beautiful design and makes keeping track of your weight and reaching your weight loss goals a cinch.

In today’s times, maintaining a healthy weight (i.e. BMI 19 to 25) is hard, but it’s a crucial part to staying healthy. Weight loss research has shown that losing weight has many positive effects: You will feel more energized, sleep better, improve your immune system, lower your blood pressure and even increase your sex drive.

Slim helps you on your journey to reach and keep your desired weight. It can remind you of stepping onto the scale, lets you set a target weight and motivates you through rewards you can unlock.

Slim is fully integrated into Apple Health. This means that Slim can import all weight data from other apps and from peripheral devices such as WiFi scales (e.g. Withings WiScale) which integrate Apple Health. So, if you're already using another weight tracker with Apple Health integration, switching is easy since all data will be directly imported to Slim.

Most important Features:
- Enjoy a stunning user interface
- Log and track your weight and BMI
- Set and reach your target weight
- Set a recurring reminder
- Unlock rewards
- Sync all data with Apple Health
- Lock access to Slim using Touch ID

- Unlimited charts

- data export
- passcode protection

Superb app


Let me start with the ui design which is absolutely brilliant. It has a clean interface which gorgeous design and easy to her controls. I've been using this for keeping a check on my weight and bmi. The statistics given by the app is also brilliant. Overall I just love the app. Great job by the developers.



Easy to use app and a great tool to track your weight progress. Wish there could be more features like for Apple Watch in the future where you could just use microphone to record your weight to the journal automatically.

Awesome design and interface

Lovely design and friendly, easy to use app, but for a health& fitness app I would have liked a bit more, not just an app where I can store some figures...perhaps tips for helping me lose weight, help in the gym with effective exercises.
