Activity tracker - fitness app

I would like to know what everyone is using and recommends for an overall fitness/activity tracker?

I have been using Strava and it is good but looking for better if there is something out there.

- I have done research and google searches, don’t need that from anyone.
- I need your recommendation based on you having used the app(s)
- please include pros and cons if you can
- I prefer A free app but willing to pay for a really good one


Thank you in advance for contributing your experience and suggestions

Cheers.
