Wake up exactly when you need to—even on long rides. 🚆 DestMate is a smart, location-based travel alarm for commuters and travelers. Set your destination and get alerted as you approach, privately through your headphones or earbuds. Includes a time failsafe, missed-stop alerts, ETA tracking, QR alarm sharing, and offline maps. Battery-efficient, privacy-first, and perfect for napping on the go. Arrive awake, not anxious.

Love this — turning commute anxiety into a simple, location-smart alarm UX 🙌

@zeiki_yu Thanks. When I was solo traveling in Europe, changing destinations every couple of days, mostly by bus and train, I really needed an app like this to help me sleep better during the journeys. That’s why I made it. I hope this helps more people.
How accurate is the location-based wake-up on long rides or underground routes? And does the offline mode still work well in areas with spotty GPS? Congrats on the launch! love the idea of arriving awake, not anxious

@paul_shaburov2 The app uses your GPS data in the background (only when you have an active alarm), so the accuracy depends on your phone’s GPS accuracy. The offline mode is actually a fallback time that you can set yourself, based on the ETA shown in the app or in your phone’s default map apps. If the location is not available, the alarm will still play when the fallback time is reached. This fallback mode is like a normal time-based alarm, but the sound plays only through your earphones and not out loud.
@noob_dev this is a big coincidence. I was thinking about this solution when I almost miss my train stop at Belmont yesterday. when is iOS coming?

@ayobamiu I wanted to ship Android and iOS together, but iOS has much tighter background restrictions than Android. While iOS does allow background location and notifications, it doesn’t allow third-party apps to reliably play a persistent “alarm-style” sound when the phone is locked, especially with custom audio routing like earphone-only alerts. So iOS is unfortunately not possible
This is a clever solution for commuters and travelers. From a systems perspective, I’m curious—how do you handle the location-trigger accuracy in low-signal areas like subways? Love the focus on 'earphone-only' audio for privacy. Great launch!

@iambel0ved The location depends on the device’s GPS. If the GPS is unavailable or inaccurate, nothing can be done. For such trips, there is a backup time option that you can set based on the ETA shown by other map apps (e.g., Google Maps). You can then set a time alarm, which will play through earphones only.
Nails the pain point of “being afraid to sleep while traveling.” Technically, it’s a blend of geofencing + offline maps + low‑power location tracking—key challenges are balancing accuracy vs. battery drain and cross‑country map coverage. Watch for: dynamic wake‑up adjustments based on real‑time transit data, support for fully offline mode (privacy + data saving), and reliability of background location across platforms (especially iOS restrictions). If it delivers low power use with high reliability, it could become a must‑have for frequent travelers. Downloaded—testing on a cross‑border train trip this week.

@nancelu Great, let me know your feedback after the trip
