Pocket Penjing

the breathe easy tree

How much do you know about the air you breathe?  Pocket Penjing is a  miniature tree in your pocket. The App grabs live data to make a cherry blossom tree grow in front of your eyes in 3D using augmented reality.

Show your friends - anywhere you place the graphic marker, the tree grows. On a table, balcony, the side of the road, a classroom or your office.
Beta Testing now. Available soon for Android


  • Live data
    Spin the globe with a flick of your finger and select an air quality station. Pocket Penjing will then use the live data from that station to influence the way your tree grows.
  • Air Quality
    We'll give you the numbers, but the 3D tree will also let you know about the weather and air quality. Too hot, dry or polluted? You can override the live data to keep your tree healthy. Shame we can't improve the air we breath so easily.
  • Augmented Reality
    Watch your tree grow and blossom, anywhere, in realtime 3D using mobile augmented reality. No need to download a separate App, it's all part of Pocket Penjing.
  • Coming soon
    We're doing our first user testing now, planning to get the App ready for the spring cherry blossom season. If you'd like to be part of our second round of testing then let us know.

Pocket-sized posts

  • Pocket Penjing trees
    grow anywhere

    Anywhere that you place the easy-to-print black and white marker image, the tree will grow. Place it in your friend's hands, put it on your driveway, in a pot, on your cat's head or on top of your cup at work.
  • So easy your
    Dad can use it

    No separate AR app, it's all built in. There's a video tutorial to guide you whenever you need help. Take photos as you go and save trees to reload later.
  • Let's talk about
    the weather

    Poor air quality? Too much sun? Not enough rain? Is the humidity just right? Icons will show you if conditions are good for tree growth and let you compensate for bad weather and pollution. If the tree is struggling to grown, how might those conditions be affecting you?.
