Bodha Converter is an android app I made a while ago which I only got around to publishing recently. It allows users to convert between Binary, Octal, Decimal, Hex and Ascii with a zen like approach.
It supports general (Binary , Octal , Decimal and Hex ) conversions up to 2^63-1 in their respective formats. It also supports Ascii characters in the range of NUL to DEL (0 – 127)
A convenient table is also included for quick lookups also in the range of 0 – 127
This app collects no personal data. The internet permission is only required to serve advertisements. It can be obtained from the google play marketplace
Hope you find it useful.
