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

Warblington Sara ,

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.

The app does not track correctly and support team does not help.

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.

I'm no critic, but... ,

Nice app

Liked it better when I did not have to pay for full functionality.
