Interesting App and I usually go for the paid option, but this one is not ready. There are far too few simulations to warrant a yearly subscription of $13. Seems a one time pay at this point would be appropriate. UPDATE: Your analogy is flawed. My point is that your app is totally locked but it did peak my interest and would probably pay at a lower price point. But, I guess the 5 minutes I spent installing it and going through the tutorial will be it for me.

We can not provide lifetime updates and services with a one time payment. A daily busticket in Switzerland is 13$ which cannot be used on the next day either. A lunch costs about 13$ a day. If you show me a place where you pay for these services once for a lifetime, we will change the payment plan.

You can create your own maps with the editor! Buy a subscription and access by selecting the templates in the menu above the scene selection.
The app will never be free because I have to buy food and pay for rent

Undesired charge in my bank account. The app is fantastic to understand boat dynamics at harbor. And I fully reccomend it for someone trying to learn about it (I would rate it 5 stars, if I did not feel stolen). I purchased a 3 months subscription and I found that they charged me again 3 months later without my awareness or consent. When I contacted the developer, he did not offer much help. Just said, it was my issue with Google... disappointing

Goolge is managing all transactions. There is a clear warning during the purchasing process! A subsciption can be cancelled at any time !
We have no influence on googles transactions - this is what we told you!
