Pixami

What we built

• 01One-tap check-in with a ring counting down to the deadline, turning amber near it and red once overdue
• 02Reminder email at three-quarters of the window, alert to up to three contacts at the deadline, and an all-clear when the person checks in again
• 03Each reminder and alert claimed by a single conditional write, so overlapping scheduler runs cannot send it twice
• 04No passwords: a hashed session token in a cookie, and one-time emailed links to sign in on another phone
• 05A daily reminder from the Quran or Sahih al-Bukhari and Muslim: 365 entries, each reference checked against its source
• 06Installable on phones, and runs on free tiers: an external scheduler calls a secret-keyed endpoint instead of a server that never sleeps

A note on these screens. Built to test the idea before launch, so it has no users yet. The screens are real captures from the running app on a demo account; the names and emails in them are invented. The promo video is built from those same screens, with an animated opening scene and an AI voice-over.
