PlantAD is a free Android app developed by Green Tech AI. It is an educational and reference app that helps you identify plants, insects, mushrooms, and crystals by just taking a picture. The app has a database of over 1,000,000 individual plants that is updated every day, making it easier to identify any plant you come across.

One of the best features of PlantAD is the "My Garden" section, where you can create a collection of your personal favorites. Additionally, the app provides you with information on how to care for the plants in your garden, with suggestions for watering, soil, fertilizer, and more. The "Pest & Diseases" section is also useful, with thousands of common diseases and treatments available to help keep your plants healthy.

Overall, PlantAD is a great app for anyone interested in plants and nature. It is user-friendly, easy to navigate, and provides accurate information. The only downside is that it is only available on Android 13.0 and higher.
