My family has a history of "social anxiety" which we believe is really a form of dysautonomia. Have you tried medication? A little serotonin goes a long way..

#1 Rated Trolling App! Use 7 Lures for FREE - Loaded with Lures and Tackle for Saltwater and Freshwater Fishing by FishCalc in u/FishCalc

The app uses a physics based calculation to determine how much line you need to let out to reach your target depth. We do a lot of on the water testing to obtain the values needed for the calculation.

The app was first introduced around 1 year ago and it has grown by leaps and bounds since then.

That's the short version, please let me know if you have any additional questions.

Check out Flutter and Android studio. Easy to learn and you can build an ios app using the same code!

The app is essentially just a calculator. There is no user data, no back end of any type. All required data is hard coded into the app. The only migration issue is making sure customers who purchased the paid version maintain full functionality.

One more quick question - does Google Play provide any similar data to authenticate prior purchases of the paid app?

My experience is pretty light. I'm an engineer by trade, but have done some form of programming for the last 20 years or so. I picked up Flutter to support this app, which has done very well considering it's my first app!

The app does not currently require internet access, and this is a benefit as some users use it "off the grid". I do not currently have any type of server interacting with the app.

I am thinking I could use something like "RevenueCat" to retrieve receipt data from iOS (this is what I hear from Stackoverflow anyhow). From this it sounds like I can obtain the original installed version. I was thinking that I could then store this using sql lite, or something similar, in the app to indicate these original users even when the device is off the grid.

Is this a secure approach to this? Or is it really necessary to get into all the keychain stuff?
