Hey Product Hunt, This started because someone close to me works 2 on / 2 off and still counted days on a printed sheet stuck to the fridge. What bothered me is that a rotating shift pattern is completely predictable. 2 on / 2 off is a formula. But every app I looked at asks you to tap in each shift by hand, month after month, for a schedule that could be generated from four pieces of information. Two things I found while building it: 1. Almost every known competitor - When I Work, Sling, Shiftboard - is a management tool for scheduling a team. Nobody was building for the person actually working the rota. That gap is the whole product. 2. Shift work is not a Silicon Valley problem. It is Polish factories, Czech manufacturing, Romanian logistics, Indonesian assembly plants, Turkish hospitals. So I localised into 18 languages, and the interesting part was that translating keywords properly matters more than translating the app. French workers search "3x8" and "travail poste". Poles search "nocki". Czechs say "turnus". None of that comes out of translating "rotating shift pattern" from English. It is free, offline, with no account, no ads and no subscription. Everything stays on the device, which matters when your users are in a basement, on a plant floor or in a hospital corridor with no signal. Android only for now. Two things I would love input on: whether iOS should be next or whether I should go deeper on Android first, and how to monetise something like this without breaking the "no ads, no subscription" promise that is currently its main selling point. Happy to answer anything.
