BeatTime: Universal Clock

BeatTime is one universal time for the whole planet. Instead of timezones, the day is split into 1000 .beats (1 beat = 86.4 seconds), anchored to UTC. @523 is the same moment in Tokyo, Berlin and New York — no “whose time is it?”, no AM/PM, no timezone math.

WHAT YOU GET
• Live @beat clock — always the true beat (tightly synced to our time servers), with optional centibeats for two-decimal precision.
• Time ⇄ beat converter — translate any local time to @beat and back, instantly.
• Home-screen widget — multiple watch faces, including a ticked ring inspired by the BeatTime logo and a dual ring that also shows your local time. Set a different face per widget.
• Full-screen clock mode — a big @beat clock for your desk, your nightstand, or the cover screen of a flip phone.
• Google Calendar (optional) — add @beat to your meetings so every guest sees one universal time, or quick-add an event with @beat (no login needed).

PROOF OF EXISTENCE — FREE
Stamp any photo or file with a tamper-proof timestamp. Only the file’s SHA-256 hash is sent — your file never leaves your device. Each hash is recorded in a public, append-only log, sealed every week with an Ed25519 signature and anchored both to the Bitcoin blockchain (via OpenTimestamps) and to an independent bank reference. Later, anyone can verify the document existed at that moment — and download a PDF certificate.

PRIVATE BY DESIGN
No account. No ads. No analytics. No tracking. The clock and converter work fully offline and re-sync the moment you’re back online.

OPEN & UNIVERSAL
Built on the classic 1998 idea (1000 beats a day), but anchored to UTC and open, with a free public API. Available in 11 languages.

One time for Earth. Just @beat.
