Is there a metrics tracker service specific for any app

So far I have tried Hotjar and Mixpanel
Hotjar is great for measuring the effectiveness of sales and landing pages and seeing what users are doing where they are slowing down or dropping off
Mixpanel is great for analytics like Session times, tracking custom events etc.

But as an early founder, like most of us here, I want to know what a user is doing across many days, during the duration of the trial.
For example one user can be creating todo lists every night, finishing them every day and eventually converting.
Of course this will need backend code integration, I'm aware of that and currently I'm using a quick solution I hacked in a few hours but I'm wondering how the more successful people are doing it.

Is there a service that will track the user and tell me what actions he takes day by day?
