Hey Product Hunt! 👋 ## The Problem People living alone or away from family face a dilemma: daily check-in calls feel intrusive, but family members worry when they don't hear back. ## The Solution CheckOnce is a minimalist approach: 1. Tap a button once per day (takes 2 seconds) 2. If no check-in for 48 hours, emergency contacts get an email 3. That's it. ## Key Features ✅ One-tap daily check-in ✅ 48-hour countdown timer (visual reminder) ✅ Automatic email notifications ✅ Optional daily reminder (e.g., "Time to check in" at 8pm) ✅ Privacy-first: No location tracking, minimal data ✅ Free for 1 contact, $0.99/month for up to 6 ## What it's NOT ❌ Not a medical device or emergency alert system ❌ Not location tracking or surveillance ❌ Not a fall detection tool We track inactivity, not safety. We notify contacts, not emergencies. ## Who is this for? - Solo travelers and digital nomads - Elderly people living independently - Anyone living alone or far from family - Adult children concerned about aging parents ## Feedback Welcome Would love to hear from the PH community: - Is the concept clear enough? - What features would make this more useful? - Any concerns about privacy or usability? ## Get it now 🔗 checkonce.app → Google Play Thanks for checking it out! Happy to answer any questions 🙂 P.S. iOS version might come if there's demand - Android only for now.
