User Reviews

★★★★☆

Really excellent app for learning time. The only issue I've found is that the buttons to select a previous level and repeat (freestyle mode) don't work. So there's no way for the child to go back to practice a level they're weak on. There's a redo button before you progress to the next level, but you can't return to it once you progress. The intro is also annoyingly long when you play regularly.

★☆☆☆☆

It's quite hard to control the placement of the clock hands (fire tablet) your fingers kind of get in the way of being able to see the clock face. My 6yp struggled with this, I had a go and also felt it was awkward to use.

the best one I've found - explains the clock amazingly well and very engaging especially his little dances :) only bugbear as others have said is you can't go back and select levels :( otherwise better than the paid apps - succinct and simple and easy to understand :)

★☆☆☆☆

It keeps freezing after completing a level and won't let us progress. We have to choose the game and then reopen it to get to the new level. Devs need to fix and then I'll re rate it.
