Luck Abacus for Android

Thank you for doing such a great job developing this app! The abacus is very clear and easy to use! Love it!

Beautiful app and the best looking of the abacus' [n.b. Actually not European, but Suan Pan and Soroban toggles; gives options for both]. However, in the current distribution it freezes up and must be reinstalled. Look forward to a functioning app (one time install) after I switch from Android 5 to 6/+ and possible further updates. Good luck guys! ---- Just reread the App Store notes: last updated in 2011, so consider. (Writing 2014-12-31)

The product stops working after install. It does not respond to touch screen rendering it useless. If reinstalled it will function for a short time. Save your money, get something else.

It is lovely to work with and has nice little touches. For example, you can run your hand laterally and beads will turn/spin on their rods, and make just the sound you would expect. Very nicely done. (I do wish that I could move the bar after calculation starts, instead of it locking down. The only way to release and move it is to switch it off and back on again.)

It is also not a clean one, who needs the coins for decoration? Too much stuff around it, wont fill the screen, no transparent view, texture looks fake, all looks bad compared with the free app, which has ad I hate and would rather pay o remove it. Regret my purchase of this one.
