Promising with great support and fair pricing!
I am trying this app among others of the same category. Till now, I had great and fast support on some of my questions. Moreover, HabitHub offer nice tracking features and progress overview. Last but not least, it has a fair price of 3.99€ for lifetime premium, which is needed in order to track more than 3 habits. Most of the other apps offer way more expensive lifetime purchases or monthly/yearly subscriptions.
