My name is Stu. I did not set out to become a watch collector, but the hobby has captivated my attention and held it for years. I made Prolost Watches not to quantify my fascination, but to elevate my enjoyment of it. • Every watch I own is entered into the app. Every detail I want to remember, in one place. • Every day I wear a watch, I log it. Over time, this reveals insights. In the moment, it adds to the ritual and intentionality of choosing a watch for the day. • Throughout the day, I check the app. It surfaces memories of watches and my adventures with them. It helps me enjoy the watches I’m not wearing today — even ones I’ve let go. • If I snap a wrist shot, I add it to Prolost Watches. These moments appear on the Map and in the Events timeline, and bubble up later for ongoing enjoyment. • Every turn of the calendar page, I enjoy the Manifest, a report of my activities and wear habits for the previous month. • When I sell a watch, I log that too. My watch finances keep track of themselves. Prolost Watches is a one-time purchase. There’s no subscription, no ads, no account. Your data is secure and private. I hope you’ll find, as I have, that Prolost Watches is more than a tool. It’s a way to hold your entire collection in your hand. To understand it, manage it, illuminate it. But most importantly, to enjoy it.
