An indie developer. Mostly iOS and macOS apps. My most successful and established app is Time Nomad, an advanced calculator of celestial body movements targeted at the research oriented segment of astrological community. It's more advanced that you may think, and no, it doesn't do horoscopes, only pure astronomy involved (with subtle tinges of philosophy). https://timenomad.app
Other apps like Sing Scales and 3EM can be found on my App Store pages.
Regular (short) poetry about existence and mysteries of life.
