DayTap – A privacy-first dead man's switch iOS app

The UX is delightfully minimal — one big "I'm OK" button, configurable guardians, and a check-in window — and the author leaned on Claude Code plus multi-role LLM reviews to shore up gaps in their Swift work, which is an interesting workflow experiment. The privacy-forward touches shown on the landing page (encrypted, no GPS) are promising, but critical backend details and delivery guarantees are missing, and the core idea is familiar rather than novel.
