Hey Kathryn, I’ve been tinkering with a lightweight travel‑itinerary app that syncs in real time, but I’m debating whether to use a ready‑made map API or build a custom route optimizer. As someone who’s navigated dozens of cities, what features do you think every traveler’s planner should have to keep the trip smooth and memorable?

Hey! If I could pick the few must‑haves for a travel planner, I’d say: a solid map that works offline or at least loads fast even on 3G, a real‑time route that adapts to traffic or public‑transport hiccups, and a local‑insider guide that shows you off‑beat cafés, markets or street art. Add a calendar that syncs your flight, hotel, tours and even the sunset times, so you can plan a stroll at the right hour. A budgeting widget that tracks expenses in multiple currencies, a little language help for key phrases, and push alerts if a place is closed or if a sudden weather change hits. And, of course, a “memory box” where you can drop photos, notes or a quick diary entry next to the spot on the map. That mix keeps the trip smooth, gives you that surprise “wow” moments, and lets you remember why you love each city.

Nice list, Kathryn. I’d first lock the offline map with vector tiles and a local cache—Google’s or Mapbox’s SDKs can do that, but a custom tile server gives you full control. For the real‑time route, a lightweight routing engine like OSRM or GraphHopper on a local instance keeps it fast and lets you tweak weights (walk vs bike vs bus). The insider guide should pull from a curated dataset, maybe a local JSON or SQLite, and support a quick search index for fast lookup. Sync the calendar with iCal or Google, and tie sunset times to the geolocation API. The budgeting widget—just a simple table with a currency conversion table pulled from an API like Fixer.io. Add a tiny dictionary snippet or use a language‑learning API for on‑the‑spot phrases. Push alerts can be handled via Firebase Cloud Messaging; just keep the payload minimal so it doesn’t drain battery. The memory box is cool—store photos in the device’s media store and link them to map points via a small metadata table. If you want to keep everything lean, store everything in a single SQLite database with proper indexes; that way you can pull a city’s data in milliseconds even on a 3G line. Just remember to keep the UI minimal – every extra button is a potential bottleneck. Good plan, but make sure you prototype the offline flow first; that’s the trickiest part.
