Rootlet, a toddler app that knows when to stop

Field notes

Rootlet organizes its material into three age bands, with activities ranging from sensory taps and first sounds to sorting, patterns, mazes, counting, and first letters. The site describes a parent-controlled five-to-30-minute play window and an automatic transition into a watercolor sunset when time expires. It also states that the app works in airplane mode, stores data on the device, and includes 36 free games alongside a one-time purchase option.
