I like this app. I let my 3 year old son to use it as a learning tool.
The goods:
* Each "module" of the solar object is kept short, so it is appropriate for young children like my son.
* The "quiz" or what it is titled "PLAY" helps to evaluate (in a fun way) to evaluate their learning.
The "could be better"s:
* Provide better "indexing" for the learning option, so the learner can choose where they want to start or what they want to learn immediately. At this time, we must always start from the sun, then keep pressing FWD button. Everyhing starts all over again, everyime we want to start.
* Animation need more improvement. After a while, rotating objects just kept on moving the same way with the same background. The only thing that Astronaut Ashley does is moving her mouth. May be make it more like an animated slideshow that changes with the fun-facts.
* With the last comment, I think it would be good to provide an option of showing a sub-title. Instead of merely listening to Astronaut Ashley, children can also read through what is being taught.
* Add different level of learning with other fun-facts for more advanced level. This will allow children to learn more after they finish learning the earlier level.
