Looking for service like AppAnnie/SensorTower to optimize app rank/install?

Hi,

I’m looking for a service like AppAnnie/SensorTower to optimize my android app rank/install?
As far as I know, AppAnnie/SensorTower is charging fees every month.
I’m looking for those that allow one time payment service to try it out…

Thank you.

You can try some alternatives which cost less and provide a free trial so you can test them like:

https://appfigures.com/
https://www.apptweak.com

Or you can try a free service like:
Mobile Action - App Store Optimization and App Marketing

These are services that app developers I have relations with, know that they have used in the past.

i’ve used apptweak and have no complaints about it
