## What is synth?

synth is a hermetic tool for self knowledge. 

Designed as an open and adaptable system, synth provides the place to record cycles and events, and know yourself over months, years, decades. 

With synth you can: 
+ record events and cycles in your life
+ view your events alongside celestial events (eg. moons, equinox, retrogrades)
+ use ancient symbols and signs to keep your records
+ record voice notes and transcribe texts
+ define your own algorithm for how future events are predicted
+ customise all your colours
+ get notified of upcoming events
+ your data is stored encrypted on device and if you choose, your icloud for backups.
