Can a mobile app help you drink more water?

Review of iOS app “Plant Nanny”

I’ve been using “Plant Nanny” for the past two weeks, and as amazing as it sounds, it’s actually helping me drink more water everyday.

To be honest, I would never have believed it myself, just like I would never have believed that there were sea lions (actual sea lions) hanging out at Pier 39 in San Francisco everyday.

More importantly, it’s been over two weeks and I don’t even hate this app yet. For 1. I’ve been drinking a lot more water, and for 2. It doesn’t consume huge chunks of my time everyday and I don’t have to feel guilty about it afterwards. It also does not constantly hound me for money.

Except random commercials are kind of annoying…

How it works

The app is built on the ingenious idea that the optimal amount of water you should drink each day can be calculated based on your body weight and general level of activity. Knowing this, the app creates a virtual plant that needs the same amount of water as yourself. If you remember to water the plant, it will grow to become bigger and cuter each day.

All well and good, but how does the app make the user drink water each time they water the plant?

The answer is, of course, is that it can’t. But after a while it just feels like not brushing your teeth and going to bed. It’s a nagging, annoying feeling, that you’re cheating yourself out of something which, after all, is good for you.

For me at least the app works pretty well. I’ve been drinking way more water than I used to, and the only down-side has been that I’ve also been going to the bathroom a lot more than I used to (especially at night).


All in all, I really like this app. It’s so simple and clean, and actually accomplishes what it sets out to do, which is to make me healthier by reminding me to drink more water. It’s also very lite and uses up less than a minute of my time every day.

Oh yeah, did I mention that the plants you get to grow are really cute? When I told my GF she even became jealous…

“The cutest of them all!”
