That is so inspirational! Welldone Adam!
I am thinking that Google Subscriptions is the way to go because you make one app, you sell it for one price, people buy it once then sales die down.
We need a way to build up our businesses so if you make an app and give it away for free you'll get lots of downloads but people can subscribe for a dollar to get the extra functionality and a dollar is not going to break the bank.
Of course that dollar only lasts for one month but that's plenty of time for the users to decide if they want to keep on subscribing and you can do a special offer, a year for ten dollars.
I'd love to hear your views on the idea (I'm sure lots of people are already doing it).
I expect many will think that a dollar per month, no-ones going to fall for that but they already have the app installed and its right there in the menu so maybe they will.
When the subscription runs out it just reverts to free mode, they can still use it, subscribe at any time, subscriptions accumulate etc.
If the app turns out to be a success then the next stage when you next update the app is to have the server that takes the subscription payments to not be Google Subscriptions to shake yourself loose from them stealing 30% of your hard work
I think the secret to success is a series of hooks, firstly you hooked them into installing your app because it was free, then you hooked them into subscribing for a dollar for a month to try out the extras, then your extras are so good that they continually subscribe or go for the one year ten dollar option.
So we all become hookers
