nd sitters relying on my faulty memory felt insanely fragile. That’s why I built Nudge Device.

Nudge is a compact $49 device you place under any pill bottle or weekly organizer. At the scheduled time it pulses green lights and beeps (30 / 35 / 59 min). Lift the bottle and the built-in IR proximity sensors + accelerometer instantly confirm the dose was taken, log the exact time, and silence everything. If the bottle stays untouched after 60 minutes, it automatically sends an email and push notification to the user and any caregivers added.

No buttons. No scanning. No “open the app and tap taken.” Just reliable confirmation.

Tech: ESP32, custom algorithm IR proximity for rock-solid detection, Flutter front-end (iOS/Android), AWS IoT Core + Lambda backend. First production run of 500 units arrived last week. HSA/FSA eligible and price is going up soon.

Today my son is seizure-free, and Nudge is the reason we never miss or double-dose.

Curious what HN thinks. Anyone shipping consumer health hardware? What killed you early on? Parents or caregivers here, does this actually fix the multi-person chaos you live with?

Tear it apart. M Giller / solo founder18:T7d8,I’ve been lifting for years using complex methodologies (Mentzer HIT, Kuba Method, FST-7) and got frustrated that existing trackers are just glorified spreadsheets. They record what you did, but they don't tell you what to do based on your fatigue or biomechanics.

So I built Arvo (https://arvo.guru). It’s a "context-aware" AI coach, not just a logger.

The Problem: Standard apps use static linear progression (add 2.5kg every week). But if you are following a fatigue-based system (like Mike Israetel’s RP or Kuba), you need to autore
