This is more of just me testing the waters here but hypothetically if there was a website and app (more than likely the website would be first and the app would be created later down the road) that was like an all in one type of thing so for example it would have logs for your workouts, different types of exercises, a calorie calculator, recipes etc. would people actually use that kind of software or would i just be wasting my time
for clarification it would launch with a couple of features but more would be added as time goes on

I'm using MyFitnessPal, an app that allows me to track my workouts, calorie intake, and more. There are many users in this app. If you can offer unique features or a better user experience than existing apps, then it’s worth pursuing.
