This app was originally designed to help kids to improve their Spanish skills at school. But it can be used also by spanish language students. There are three activities: Converting units: you are asked to convert quantities between different units for measuring length, volume and weight. You get points until an error occurs. Accent mark: the app will show you a word without accent mark. Then you have to press on the vowel in which it should be placed, or indicate that there is no accent mark. BV .: the app shows you a word with a missing letter. Then you have to choose whether it should be placed a B or V. You can use this app to improve your spanish language skills.
It is also useful for people not so young remember things forgotten.
