Speller is a simple macOS application for converting numbers into spelling form in Russian.

Since the conversion process is highly dependent on the language, the program is available only for Russian. I think, that is unlikely to get it translated into other languages without modifying the source code, but anyone can join the project on SourceForge.net.

System Requirements:

1. • macOS 10.4 or later
   

2. • PowerPC or Intel CPU
   

3. • 512MB RAM
