20 Second Drawing is a short and simple drawing app that helps children start drawing without pressure. By drawing for just 20 seconds each day with a new topic, children naturally build habits of free imagination and expression—without right or wrong answers. How to enjoy it Random topics: Each session introduces a different topic to spark imagination. 20-second limit: Helps children focus on drawing for fun rather than trying to be perfect. Color selection: Simple expression using black, red, blue, and green. Gallery saving: Drawings are saved with the date and topic, allowing you to record a child’s growth over time. Delete feature: Unwanted drawings can be removed directly from the gallery. Sharing: Easily share images that include both the topic and the drawing with family and friends. Free users can draw up to 3 times per day. With a one-month subscription, you can use the app without limits. If you have already subscribed, you can restore your access using Restore Purchases.
