Great

The only programming calculator I’ve used for years now. It is simple, functional, and no ads, subscription, or annoying features. Highly recommended for your hex or binary conversion needs.

希望として3点あります
1、2進表記のとき該当ビットをタップすると反転するとうれしい
2、希望桁に対してゼロ埋めしたい
3、選択した表記以外もどこかに表示して欲しい

Solid app

Thank you, dear dev, for having enough faith in users to put out a great paid app with no ads or in-app purchases. It’s ridiculous what some apps have become.

Totally worth a dollar. And look at that download size: less than 10MB!! In 2019!!

Great app except...

AND function doesn't work as expected. E.g. Binary 110 and 11 returns 0?? Expected 10

Response from developer

Thanks a bug report. I'll fix it on the next version. The issue occurs by 'AC/C' after '='. Try workaround that double tap 'AC/C'.
