I love this
I have been looking for a tenkey calculator and this one is close. If you develop a a real tenkey I am a customer.
Can't see the bottom line of number buttons on my model in portrait view (0, ., +/-, +)
wish I could toggle haptic feedback
This is the one I've been waiting for. An rpn calculator to replace the built in with buttons large enough to hit.
Not bad. Need to be able to run off the vibrate when hitting the keys.
Could not figure how 2 use this, no clear or = button, uninstalled.
Nice basic calc
The U (**)
Basic rpn is ok, but would much more useful if stack could be rotated (argument 2 --> arg 1). Looking fwd to next rev.
Excellent quick calculator and RPN remains the warp drive for embedded calcs. Rock solid operation on Droid.
