Everything you described - periodic reminders and checklists - can still be done with the stock applications.
You can even automate turning off bluetooth and airdrop yourself, again, using the built-in automation functions.
So again: what does this 'security' app you're pushing as so necessary, do that cannot be done with the OS's built-in apps?
Also: can the peanut gallery nonsense about iOS being "busy encouraging you to enable" things. Bluetooth is only re-enabled if you disable it from the quick panel, and the OS tells you it will re-enable it. It will not re-enable it if disabled from the settings app. Airdrop does not re-enable itself, ever...
