The best soroban and suan pan app! Been using it for 3 years with my son and could barely wish for more. Not just a complete abacus, but a complete learning system. I applaud the developer
If one is just beginning or serious about taking their mental abacus skills to the next level, this app is nearly ideal and will help you along. It's not perfect, but provides such a comprehensive set of tools that other apps just don't have that I'm giving it 5 stars. I especially appreciate the bead count recognition and audio functions, which are incredibly useful in helping one advance their visualization skills. All exercises are also highly customizable from beginner to expert levels. Note to the developer on wish list for improving even further to help the learner: 1. Please increase font size so can easily read on smaller devices 2. If can allow verbal announcement faster than every 3 secs (in this case, for 2 digit numbers), would be wonderful. Would removing the 'plus' announcement before each addition help and instead simply call out the number alone for additions? 3. The abacus really needs multi-touch function in order for one to use correct finger technique; more like Simple Soroban. As it stands now, 8m finding the interface isn't quite fast enough for intermediate speed and above. Would absolutely love to see a multiplication and division app. Would purchase it in a heartbeat! Will recommend your app. Thanks for the hard work and thoughtfulness that went into this.
Font is to small I have a Galaxy Note 5 and I can barely read the numbers. Otherwise its a good app.
3 stars until I can use proper technique on this abacus This app is great but flawed because it doesn't allow one to move beads from different parts at the same time, which is absolutely necessary for it to be used efficiently. I'm trying to learn to use proper technique and this is totally messing me up. I would give it five stars of this small, but very serious problem was fixed.
Best abacus app available. If I have any suggestions it would be to bring in multiplication and division. Easy to use. Very effective tutorials. Different bead selection. Thank you for this app.
