What's New in Calclin

2.4.0

October 10, 2026

■ Answers kept at full precision - Answers, not just intermediate results, are now kept at full precision - The display is rounded to your chosen number of digits. Rounded answers are marked with "≒"; tap one to see every digit ■ Clearer unit handling - Pressing a different unit key changes only the unit and keeps the number 　e.g. 60m², press [坪] once: 60坪 - Pressing the same unit key again converts the number 　e.g. 60m², press [坪] twice: 18.15坪 - Tap an underlined unit to open the conversion list and convert to the unit you choose ■ New TAX+ and TAX− keys - Set up to three tax rates in "Key settings"; each key shows its rate - Works on the value you are entering and on the answer you just calculated ■ Usability improvements - Moving between Formula and Calculator modes feels more natural - Redesigned the Formula / Calculator switch - In Expert mode, switching between the roll and the keyboard is twice as fast - Redesigned how options are chosen in Settings

Not well designed

Number Keys could have been bigger.
Rolls are too short.
Too many Memory keys - M1 to M15! Normally 3 would have been enough, and customisation could have been provided, so that Rolls could be larger.
Ads poorly positioned.
Unique customisation, could have been better.
Wait for improved version before you buy.
