Hey HN,My co-founders and I have been building GridTravel, a free iOS app for planning and sharing travel routes with turn-by-turn GPS nav. We just launched yesterday after App Store approval.We're three 21-year-old cofounders and best friends since middle school. We built GridTravel after years of frustration navigating new cities on every trip we took together.The idea: most people either search Google for "top 10 places to visit in…" lists or go on social media to get inspiration on where to go. GridTravel is built around user-generated routes — actual paths someone walked, that you can follow, save, download, and discover from other travelers. Users also have the ability to create private routes and collaborate with their friends.Tech stack: Mapbox (Nav SDK + maps), Supabase (auth, DB, storage), and Swift. Native iOS for now, Android coming soon.Our two real cost drivers are Mapbox Search (hit when users create routes) and Mapbox Navigation (hit when users use live navigation). Both have free tiers, then scale with MAU. We launched fully free to remove the barrier to entry. Revisiting pricing in Year 2 once nav costs start burning a hole in our pocket.Current state: we're in the UGC cold-start hole. The app's value scales with route density in a given city, but route density requires users, who require routes. Classic chicken and egg. Our current plan:
1. Manually seed 25–30 routes per city, starting with 5-10 priority cities where we have personal networks rather than spreading ourselves thin.
2. Short-form content as the primary social channel (TikTok, reels, shorts). Doing A/B testing: whether route walkthroughs convert better than informational/skit videos.
3. Partnering with micro-influencers in those cities (5k-50k following) for in-app routes plus cross-posts on their channelsCurious what HN thinks. Especially anyone who's shipped a UGC product. What worked for you on cold start? What do you wish you'd done differently? Happy to answer any questions about the app, costs, etc.App link: https://apps.apple.com/us/app/gridtravel-local-routes/id6762...

AI Executive Synthesis
A user-generated content (UGC) driven alternative to traditional travel guides and social media inspiration, focusing on shareable, navigable real-world paths.
GridTravel addresses the user pain point of fragmented travel planning by centralizing user-generated, navigable routes. This UGC-centric approach differentiates it from generic "top 10" lists, offering authentic, actionable travel experiences. The core challenge, the "UGC cold-start hole," is a critical market implication for any platform relying on user contributions. Their strategy of manual seeding, short-form content marketing, and micro-influencer partnerships demonstrates a tactical approach to overcome this. For SaaS in the travel or social platform space, this highlights the necessity of robust community building and content acquisition strategies. The reliance on Mapbox for core navigation functions also underscores the importance of scalable, third-party infrastructure for location-based services, with cost implications tied directly to user activity, necessitating careful monetization planning beyond initial free tiers.

This looks great - I funnily had a very similar idea a while back that I never got the ball on rolling on - so it's great to see you've built this. I unfortunately can't test this right now as I have an AndroidSome ideas I had back then on the business side of things - you could explore getting travel influencers on board to market it and create their own custom itenararies. Then you can also connect to booking websites to earn income and give commission shares to route creators.
Super cool! Unrelated to the idea itself, but it seems like (at least for me) the images on the desktop landing page aren't rendering on either chrome or safari
This is for the US only?

Awesome job! Congrats on the launch!I like the idea of exploring what others had found before. Maybe it doesn't need to be gear towards just travel but also this gives an opportunity for locals to explore places they've never knew before too?I've also recently launched a walking app - made for myself but thought others would enjoy too. I had added an anonymous collective walk counter which encourages others to keep walking.BTW, Mapbox does give sponsorships to projects/apps for displaying how their product is being used so once you get to a certain level you could submit a form for it. I know this project was sponsored by them: https://gpx.studio/Here is my project if you are interested to checking out. Feel free to take any feature you find in there for your app.

I love the idea. Unfortunately, not available in my country. I hope it to be successful and see this app in my country in the future.

Wow, this gives me such bittersweet feelings!This is almost 1:1 with a project we worked on several years ago. Unfortunately it never launched - founder ran out of money. It was one of my favourite projects we’ve done and I genuinely believed in the concept, so I was sad we couldn’t see it come to fruition. But glad someone else is giving it another go!Without giving away anything confidential, I can say your cold start plan is very similar. Can’t say it’s a good or bad plan because we never saw it executed in practice… but it’s not unreasonable!I think distribution and stickiness will be a challenge. Even if you get enough content that users will have a great first experience, most people don’t travel that often, so getting them to come back regularly won’t be easy.Best of luck - would love to see this succeed!
