What Users Dislike About the App
“The jump from level 1 to level 2 is too difficult. I really wish level 2 focused on time to the half hour, not on something like 5 minute intervals. Children need to know how to tell time to the half hour before they start learning about increments like 5, 10, 15, 20. Level 1 is perfect because it only uses time to the hour. Level 2 should include the level 1 time, and then time to the half hour (6:30, 1:30, 11:30, etc.) ONLY!”
“This is an interesting and different way of teaching time. The progression from simple concepts to more complex concepts is done in a nice fashion. That being said, there should be more opportunities for practice at each level. The main issue with this app is that naming the time for five after the hour (for example, 9:05), it displays the time as 9:5. If this is corrected and more practice opportunities are included, I would certainly change my rating to 5 stars.”
