On the flip side of the best diet and fitness apps, here are the top 5 worst ones.

If you can't afford or don't have the time for a personal trainer or weight coach, there are some great apps out there to help you with both. But some aren't so great.

Here are the top 5 worst fitness and diet apps based on app quality company Applause's analysis of  3.3 million app store ratings and reviews for some of the least popular diet and exercise apps (to qualify for this analysis, apps had to have 10,000 or more reviews; apps could be free or paid) to determine which apps users gave the least favorable reviews to.

The least favorites were rated by users based on elegance (e.g., delightful design), security (e.g., secure login, no perceived risk) and stability (e.g., no crashes, hangs or freezes)
