Time isn’t just 6:31. It’s 631 - a prime! A lucky prime... It’s the combination to the bike lock you had as a kid. It might be the last digits of the cell phone of someone you love. This is a clock for people who notice things like that. Every minute, it: • Computes mathematical properties of the current time • Surfaces number theory facts (prime, factorization, powers, sequences, curiosities) • Scrambles them onto glowing 16-segment LED displays, like your old Speak 'n Spell • Optionally finds personal number connections in your contacts — entirely on device Works great as a Mac app via Catalyst. Contact matching happens entirely on device. No personal data is ever transmitted. Usage analytics (anonymous) are collected to improve the app. If you’ve ever factored timestamps in your head, smiled at 5:12 = 2⁹, or paused at 17:29… This is the clock for you. Make every minute momentous.
