LUMI is a free Android app developed by WowWee Group Ltd. It is a fun and interactive app designed for the LUMI drone. The app comes packed with features that make flying LUMI extremely easy and fun. With the Eazy Flight feature, users can enjoy easy flight stability and one-touch stunt control. The app also includes Fun App Games that allow you to program custom choreographies to the beat of your music.

However, it is important to note that the app requires the LUMI drone to function. If you don't have a LUMI drone, this app will be of no use to you. For those who do have a LUMI drone, this app is a must-have. The only downside is that the troubleshooting process can be a bit tricky. But, WowWee Group Ltd has provided a website (wowweezone.com) to help users with any issues they may encounter.

Overall, LUMI is a great app for anyone who owns a LUMI drone. It is easy to use and fun to play with. The app is available for free on the Google Play Store.
