Telling Time Free by King’s Apps is great for any child still learning how to read a clock. This app works by playing a game. You can adjust the number of questions (10, 20, 30, or 40), turn the timer on or off, give your child a letter grade for their score, turn the sound on or off, and adjust the minute hand increments (1, 5, 15, or 60). It is free to download and there are no in-app purchases. It is only compatible with the iPad.
