Fantastic app. Much better for me than any book – LearnBridge Review

This app has helped me learn this difficult game during the quarantine. The lessons are written concisely and perfectly with lots of reinforcing drills. The app is also priced very fairly, enabling anyone to learn the basics (and then some) for free and then paying a low price for additional lessons. Great, great app.
