I made Amanita Calculator because, while producing music, I kept reaching for separate tools for delay times, note frequencies, Euclidean rhythms, tuning and harmony.
I wanted one fast, quiet utility that could stay open next to the DAW without getting in the way.
Amanita Calculator is free and includes seven tools:
• Tempo — BPM to milliseconds and Hz, straight/dotted/triplet subdivisions, and tap tempo
• Rhythm — Euclidean rhythm generator with pattern audition
• Space — tempo-synced delay, reverb pre-delay and decay calculations
• Pitch — note frequencies, octaves and custom reference pitch
• Temperament — explore N-TET divisions, audition steps and compare them with 12-TET
• Overtones — harmonic series, partial audition and cents deviation
• Harmony — circle of fifths, related keys, chords and progression playback
Most calculated values can be copied with a click. The app remembers its state, works offline and can be installed as a PWA.
It is a standalone companion rather than a plugin, so it works alongside any DAW.

No account and no ads. The web version only uses anonymous, cookie-free usage statistics; Do Not Track is respected and analytics can be disabled.
The desktop builds are currently unsigned, so macOS or Windows may display the usual security warning. Installation instructions are included on the download page.
This is version 1.1 and I would really appreciate feedback from KVR users:
• Which tool is most useful in your workflow?
• Are there any calculations or features you think are missing?
• Have you found any issues on your platform?
I hope it proves useful.
