Thanks everyone for your feedback. I've decided to release the app for free, with an upgrade option planned for the future - that is if anyone actually uses it or finds it amongst the other 2 million apps! It's still work in progress (mostly for my poor wife) as we have at least another 2k BBQs to add. Ultimately tho, I need to look at allowing users to add these by themselves, as there are just too many for us to manage and tbh, i had no idea when i started the app there would be that many public BBQs over here!
I wrote this app for myself and my family to use (and i've never programmed anything before, so I needed the motivation to learn), but maybe it'll provide some use to others too.
Thanks
