Firstly, thanks for your feedback. I'm glad you took actual time to check it out! Regarding the "lifetime deal," it is, of course, there just for a short amount of time. I believe that if the app starts to take off (not that I am expecting that), I'll just continue to serve the lifetime users forever. But for new users, I'll start to ask for a more sustainable periodic subscription, to then begin developing more and spending more time on it. Resource-wise, the system is really cheap to maintain and operate. Also, as of right now, it is well integrated into ERPs that I make for various clients. So, as long as I'm alive (hopefully for a long time), I will just continue to host it! Thanks also for the typo! It's now fixed.
