I would be fine with a subscription model if the customer service was actually better as you seem to claim the model provides.

I recently had an issue importing a logbook using arguably the most popular iOS pilot logbook app and it took a week. A WEEK! For the them to attend to my support request. A week could be 30 hours worth of flights for a pilot depending where they work.

Why do you need almost $100/year from me if you can't answer one email in 48 hours?

I've been dreaming of an open source logbook setup ever since this experience. I wish I didn't have to rely on $100/yr subscriptions to be locked into something so critical to my career.
