About One Hand Simple Calculator
It is a simple calculator app that can be operated with one hand.
By moving the calculator key to the left or right, the problem that the button on the opposite side was too far and the thumb could not reach was solved.
You can also move the calculator key to the left or right with one touch, whether you hold it with your right or left hand.
Main function
・All buttons can be reached with one hand by moving the calculator keys to the left and right
- Calculator key size adjustable
- Visualization of calculation formulas on the way
- Calculation results and formulas can be saved in history with one tap
- Simple specifications without special calculation buttons
- A variety of theme colors available
There is also a simple memo field that can be used when you want to temporarily remember the calculation results.
Perfect when you want to use the calculator with only one hand, such as holding a shopping cart at a store, holding a hanging leather on a train, etc.!
The calculator key is easy to use because it has a central position with spaces on both sides, so please give it a try.
