I once had an app that screamed at me to drink water every thirty minutes. It was like having a bossy parrot on my shoulder. I drank out of pure anxiety.
That’s the wrong approach. Your thirst is a better guide than any notification. Your body is a smart machine—it knows when it’s low on coolant.

If you just ran a marathon, walked for an hour in the sun, or binged a spicy taco challenge, add more. If you live in a desert or have the heater on full blast all winter, add more.
If you sit in an air-conditioned office like a potted plant, you might need less. Think of it as topping off your tank, not flooding the engine.
