A lot of apps need to know specifics about your ammo, and especially with your long barrel, you may be getting significantly different fps than what boxed ammo or your handloads say you should be.
You'll want at least a chrono if you want some more accurate info in an app. I know rimfire is a different beast, but at 200 yards, all the app(s) I use have been off by multiple mils between calculations and real world experience. Part is me using box FPS numbers, part is no one seems to know the correct BC for .22s, and part is probably that the places I've zeroed are not a true 50 or 100 yards (Clinton being 53yd for the 50 berm)
I know a lot of (rimfire) people use a Kestrel, but I honestly am not sure what functions it has, if it is a chrono, wind speed guage, etc. I believe it links to an app, possibly their own.
As for apps, you are unfortunately too late for easily getting Strelok (Pro), which is one of the best ones I know of. It is a Russian developer, so it isn't available in the play store unless you already had it, apparently. The free version had fewer options, but was still very useful.
I have used Shooting Solution for years, which apparently is also delisted now. Not sure why.
Lapua Ballistics is still available and I have used that. But with .22s, even their own app and shooting Lapua ammo does not show the expected results. That said, it gives you lots of options for data entry on your cartridge and is worth a download. I expect it is perfectly adequate for centerfire.
Each app has a nice feature the others are missing, so youll probably want multiple apps anyway.
I forget what scope model you have, but I think I saw a Vortex app in the list. May be worth looking into if that has anything useful in it
