This forces you to pay 100$ a year when you just wish to use your own hand made app on your own phone if you wish it to work longer then 1 week offline. While using app of someone else doesn't require that.

100$ per year x 4 years = 400$ to use your own app. What makes you think that this is how it should be?

If the whole idea that one should pay for ability to program his own device seems logical to you then perhaps some monthly fee for using your fingers to control the phone would seem logical too? After all finger touches use many features of the phone that "are tremendously powerful and useful" too.
