Features
Read full description

This is an app that allows you to easily record the growth of your cacti and other houseplants every day. No tools such as rulers are required. With AR camera–based height measurement, you can easily keep track of your cactus’s growth. Simply point your iPhone camera at the cactus to capture its length and a photo at the same time. In addition to photos and total height (cm), you can also save watering amounts and notes, which are displayed on a named dashboard. You can see the growth of the cactus you carefully nurture at a glance. You can also share your dashboard with a single tap on social media and share your growth records with others. Observe your favorite cactus every day and record its growth. The app is free to use!
