This is a poor app intended to teach length and analog time to elementary school students. In both sections, the app has a clean design that will enable students to focus, three levels to choose from, and no timer that could make students nervous. However, the negative attributes overpower the positive. Even the in easiest level of the Length section is challenging, with objects placed in the middle of the ruler. It is not obvious that the student must move the ruler to accurately measure each object, which is fixed in place. The measurements on the ruler are not accurate and should not be used to teach the length of standard units of measurement. The app uses graph paper to help students more easily read the ruler, but neither the object nor the ruler is aligned with the lines of the graph paper making it confusing. When students make a mistake they are greeted with a big red "WRONG!" and are not visually shown the correct answer on the ruler. The Time section uses a 24 hour clock which will confuse early learners asked to find the time "00:50". The clock hands move independently and are not coordinated as they would be on a real clock. In this section, incorrect answers do not receive any help; instead the hands spin to a new location and the student must keep trying until they answer correctly or quit the game. The app offers no incentives for students to keep playing and could very easily frustrate students with the poor design so will not be a good choice for most students.
