Is there a way to make a phone automatically stop charging when it reaches 80% and automatically begin if it's at 20 - 25? That would probably be a lot easier than having to monitor it all the time. I bet there's an app for that.

Just let the phone charge. It already monitors the charge level, turns it off when the battery is full, and turns it on again when it drops a little. Any efforts you make will have a negligible improvement on battery life and longevity.

Actually I doubt there's an app for that. There are apps that will alert you when the battery level goes above some threshold, but I'd expect control over charging to be a much lower-level function than an ordinary user app could affect.
(In fact I'd be a bit worried if an app could alter the charging system, since if you can mess with that you can also mess it up, which would be a serious fire hazard. So I would design it so that nothing short of a low-level firmware patch could change it. I'd absolutely not let "Joe the bedroom coder" write apps that could change anything to do with the charging: I can just imagine the "battery capacity booster" which tweaks the charging control to squeeze a few more mAh in, with Note 7-like consequences...).

Many apps will alert you when the battery has charged up to a set percentage, AccuBattery is a commonly used one:

You will have to stop the charger yourself though, as Hadron mentioned.

Post #2 has it right. The phone's internal charging system does just fine on its own regulating the battery charge. At an indicated charge of 100% the actual charge level of the battery is somewhat less than that. If the charge is approaching a level low enough to damage the battery, the phone will shut itself off.
You can manually manage the charge to be even more conservative if it makes you feel any better, but don't bother with apps that claim to have any effect on battery charging or health. They don't do anything (well if you look at the permissions they may mine your data or put ads on your phone, but they won't do squat for the battery).
BTW electric cars have similar battery management since they use the same type of battery, look at the tech details for Tesla and you'll see that the batteries are not allowed to reach a 100% charge level.

Regardless how you would care for your phone's battery, it will lose ~1% per month or ~12-15% per year. It's fact because I verified it myself using the mentioned above app.
For example the original battery on my HTC 10 can only hold 75% charge after 2 years. I replaced the battery 2 months ago and this new battery actually holds 98% of its original capacity.

Poor battery design caused them to spontaneously combust. It got to the point where all of them were recalled, you couldn't get on an airplane with one, and globally carriers blacklisted them so they couldn't even be used and were forced into retirement.
Several attempts were made via firmware to mitigate the conflagration by reducing the amount the battery would charge with little success. The phone's battery design was flawed and nothing short of a redesign would fix it. Unfortunately the episode reinforced the fallacy that you should "manage" your phone charge beyond the inbuilt functionality.

I actually heard an airline informing people that the Note 7 was not permitted on board this summer, so it's not been completely forgotten even now.

I saw same thing as well last month, no Samsung Galaxy Note7 on aircraft.
Gone but not forgotten.
