A Pebble smartwatch app that stops you from napping during the day so you can fall asleep easier at night.

When it detects you're falling asleep during your configured no-nap hours, it vibrates until you wake up and dismiss it.

Features
🔬 Early nap detection — piggybacks on OS HR events + accel to catch nap onset in ~10–15 min (Pebble Time 2 / Pebble 2)
🛡️ Fallback detection — Pebble's native sleep confirmation as a safety net on all platforms
📳 Repeating vibration alarm — keeps buzzing until dismissed
💤 Snooze — 10 or 30 minutes, re-arms automatically via Wakeup API (survives app close)
📅 Per-day schedule — pick exactly which days to guard
🕐 Configurable no-nap hours — set your own start and end time
💪 Vibration strength — Gentle / Medium / Strong
🔋 Battery efficient — Tier 1 rides free on HR samples the OS was already taking; sensors fully idle outside guard window
