This app has helped me so much. I tried soooooo many other apps and games and trainers and nothing worked. I don't think it's a fit for everyone but it's perfect for my style of learning. No positive or negative incentives, just drilling it out over and over again. You can stop and start whenever. The ads do get a little annoying sometimes, but they're not unbearable.

Pretty good. It's a little hinky in regards to continuing after you make an error in the learning section. Instead of letting you start the letter again it makes you finish what's left of the messed up one which isn't too helpful since you're trying to memorize correct patterns in full. If you try and do the letter correctly after an error you just get a pile more error messages.

Great app, I like the guess the letter mode and the stats: Excellent to track your improvements and focus on the weak letters! The next improvement could be to add a 'guess the word' one, because I see that it takes me too long to recognise the letter and I need to get faster. A very annoying thing is that sometimes the ads pop up in the middle of a letter, making it impossible to recognise it (four stars are because of this...). Ready to change to 5 if this ad popup is moved to another screen.

Thank you Giulia, appreciate the review! I must admit, not being able to hear the letter must be very annoying and it's a bug (this is in recognize letter screen?). We'll try to fix this as soon as possible, but in the meantime you can use a hint to repeat the letter (tap the icon in the top right corner). Have a great day!
