Hi Product Hunt 👋 I built this for myself and then decided to share it. SyncWake keeps your alarms in sync with your calendars. If the event has a location, it works backwards from the start time — travel time plus however long you need to get ready — and rings then, not at the time on the invite. A few things I care about: It's completely private. No accounts, no sign-up. The calendar connection is 100% on-device. The alarms are real alarms. Apple shipped AlarmKit in iOS 26, which is what finally made a trustworthy third-party alarm possible on iPhone. It also warns you to charge before you leave — so you don't head out to an event with a phone that won't survive the trip. There are AI-suggested preparation lists — the app reads the event context and suggests what to bring or do, shown to you at alarm time. Both apps started in React Native and I rewrote them fully native. An alarm has to be as refined as the OS's own, otherwise you can't trust it — and if you can't trust it, you keep setting a backup alarm and the app is pointless. I was forced to make it subscription based, with a 7-day trial. This app is built for you to never open it so there is no way for me to make a profit with Ads. Let me know your thoughts on it ! Thank you for the time reading this and feel free to reach out via LinkedIn :)
