Who Makes TuneTapper
A one-person project, made for the love of music
Hi, I'm Sebastian. There's no company or team behind TuneTapper: I design, build and run every tool myself, because I love music and wanted the little calculators I kept reaching for to be fast and free. By day I'm a fullstack developer. TuneTapper runs on my spare time, so if it saves you some, a coffee keeps it going.
