I have paid for the app already, why I need to pay again for the web portal?

We use Microsoft Azure platform to host user data and do all the data conversion logic. We need to pay Microsoft every month a lot for that service. We would like to have an organic and sustainable business model which benefit both sides.

We do not have "Angle fund" that help us "burning money" to rapidly increase user base, but we are more sustainable and have full control on how to improve ATracker functions and services.
