#1: When I run out of "Hearts" it says I have to buy them to finish lesson. #2: Can't ask question why something is wrong. #3: Difficult to find Gàidhlig keyboard. #4: Works like a gambling game not a teaching tool. Ads are okay. Making me buy jewels & hearts to continue is NOT okay. I was learning Gàidhlig until it kept telling me I had to buy jewels. Now I hate this app. 2** because it does teach Gàidhlig.
