A water reminder app with no account: HydroMe, WaterMinder or Plant Nanny?

The short answer

HydroMe is the simplest: one tap to log a drink, a ring that fills up, a streak to keep, for free and with no account. WaterMinder suits you if you want very detailed tracking with Apple Watch. Plant Nanny turns hydration into a game: you grow a virtual plant as you drink.

When another app is a better fit

If you want to track hydration from your watch, WaterMinder has an Apple Watch app, which HydroMe doesn't. If you need a game to stick to the habit, Plant Nanny is more motivating.

Frequently asked questions

No, and no data leaves your phone.

How much water should I drink a day?

It depends on your weight, activity and climate. HydroMe lets you set your own daily goal; ask a health professional if in doubt.
