I built a family location app that doesn't keep history — today it got an Apple Watch app

Founder here, so take this as the pitch it is. Amya is a family locator for iPhone, built as a simpler alternative to Life360: where everyone is right now, the places they go, a heads-up when someone arrives or leaves, and a "come get me" button. No location history, anywhere. The server only ever sees ciphertext, so we couldn't read it if we wanted to. Today it got an Apple Watch app. Raise your wrist and there's the family, one row each, the same map as the phone, and "Find them": an arrow, the distance counting down, and a tap on your wrist as you get warmer. The watch holds no family key; the phone does the work and shows the watch. Things I learned building the watch side: - Treat the watch as a mirror, not a second client. Everything got simpler the day I stopped trying to make the watch clever. - A Series 4 has no compass, but CoreLocation will still say heading is available. Ask the model, not the API. - The first real wrist in the family found three bugs the simulator never would. Ship to one real watch before the store. Knowing where your people are is free. The watch, the Lock Screen ring and getting to them are £2.99 a month, one subscription for the whole family. If you've got an iPhone family, I'd love you to take it for a spin and tell me what breaks: apps.apple.com/app/id6807341865
