Get two real-size and cute calculators working simultaneously and independently by simply rotating your iPad!

Sometimes we are just hoping that we have another calculator to complete some complex calculation.

Twin Calc gives you a big general purpose HD calculator in Portrait and magically becomes two cute twin calculators by rotating your iPad to Landscape.

Its so cool and so much fun!

What you can do with 2 calculators operating simultaneously?
Some ideas for you:
☞ Its a great feature if you dont know what MR, MC, M+, M- is. Simply add up your numbers by additional calculator!
☞ You got two children, and got one iPad only.
☞ Well, you can now have a fair competition with your friends or family for seeing that who is using calculator faster!
☞ Show your friends how cool your iPad is!
☞ Use your two hands to calc if you can. (If you really can do that, please show me :D )

Features:
☞ Support 2 real-size calculators operating simultaneously and smoothly.
☞ 4 different tapping sounds. (Number buttons, Function buttons, history clear, mailout)
☞ All data/number will be restored in next run.
☞ Support continuous operation. (++, --, xx, ÷÷)
☞ Maximum 15 digits support (including integer and float)
☞ Support M+, M-, MR, MC.
☞ Support %, √, and back.

9, x, 5, % ... 0.45 (No need to press =)
2, x, 5, M+ ... 10 (No need to press =)
1500, +, 10, % ... 1650 (% substract is also OK)


Requirements:
☞ You must own an iPad and thats all!

Hope you enjoy this app!

Dual calc is handy ★ ★ ★ ★ ★
From Japan by RelishAndKetchup on 19-Jul-2010 1.1
I was looking for a simple calculator for my iPad. I tried several free calculators but were too complex or too over featured for simple calculations. I really liked this calculator for its simplicity and also having two calc side by side. I never realized how handy it is to have two calc side by side. Thank for making this app.
