Nice idea, but let me first check if even I'm capable of creating a native app. ;-)Totally get what you’re saying.
FWIW, if you have a Mac, X-Code is free. Might be worth playing around with it and see if it’s viable. Then start a go fund me to raise the $99 so that you didn’t have to spend anything out of pocket. Let the go fund me contributors be beta testers.
Just a thought.
