Before it was Yousician, it did have this feature, and I paid for it only to not have it honored once the name changed.

I want to buy yousician but i hate monthly payments and subscriptions. I don't care how much the lifetime subscription would cost but i want it. I own car, i own flat, i own land, i own computer, i own smartphone, i own all the things i have, why would i wanted to rent the software?

I notice that a number of your most loyal piano supporters are "peaking out" - and starting to turn to other software. This may be inherent in the software if there are not substantial improvements coming soon. It also suggests a natural path of rotating approaches. If this is the case, you might offer lifetime subs for the price of 2 or 3 years.. In my case, I want to support u but am unsure if i would renew at the regular rate for another year. Best always.

Allow for single up-front payments by either Visa or Paypal with *NO* automatic renewal.

The user should be able to choose a period, 1-month, 3-months, 6-month, 12-months.

Online subscriptions make me feel like I owe money and I don't like to owe. I would rather make a onetime payment and own it for life.

The question is what will guarantee they will keep posting fresh content if they roll that way?

There's a great website for learning Japanese, WaniKani.com. They didn't have a lifetime subscription at the time I wanted to use it a few years ago. A few months ago I came back to it to see that they added a lifetime subscription and I immediately used it. This feature is needed here as well. I don't like the concept of indefinite monthly payments. I'd rather pay up once and forget about ever needing to use my credit card again.
