Decent app but…
Response from developer
The current price of the app consists of the cost of development work along with the maintenance of the app and support, developer fees and taxes. Cloud services will require additional financial outlays. And cheap does not mean free - yes, AWS service is cheap in some cases, but only up to a certain level of service. We discussed with several users about the potential shape of the push notifications add-on, this topic is currently in the research phase and the result will be key in making decision about extending the app this way or not. Kind regards
