I built a navigation app that displays weather along the route
Hello HN,I live in northern part of USA where winters are snowy. Whenever I took long trips, I always wondered what the weather along the route is going to be. For those who live in northern USA, you know weather can change frequently, so when you're traveling matters a lot, not just the route.To solve this problem for myself, I built https://navimodo.com/. NaviModo calculates the route, and then checks weather along the route based on your start time, and displays weather along the route. Change start time, and the whole thing is recalculated.I am not expecting any commercialization for this, just wanted to scratch an itch, and just did it. I have ideas for adding additional features (suggestions for when to take breaks based on bad weather, auto-suggestion of start time to avoid bad weather, etc.,) but will add more as time goes by.Any feedback is welcome!

A navigation app showing time-sensitive weather along the route, with potential to differentiate by offering smart weather avoidance and break suggestions for specific audiences.
The pain
The gap
Build angle
Strengths
- Addresses a real, severe pain point (safety, significant delays).
- Founder has direct personal experience and an existing MVP.
- Clear willingness to pay evidenced by competitor freemium models and subscription pricing.
- Specific, addressable user complaints about current solutions provide a clear path for differentiation.
- Overall weather app market is large and growing, with demand for hyper-localized forecasts.
Risks
- Accuracy and reliability of weather forecasting along a dynamic route at specific times is technically challenging.
- Heavy competition in the broader navigation/weather app space (though less so for this specific niche).
- Building robust 'smart suggestion' features requires sophisticated data processing and algorithms.
- User acquisition in a competitive app store environment can be costly.
Next steps
- Gather targeted feedback on the proposed 'auto-suggestion of start time' and 'break suggestions' features from potential users (e.g., long-haul drivers, people in snowy regions).
- Conduct user interviews to deeply understand the specific failures of current 'best time to leave' features in competitor apps.
- Perform small-scale, targeted marketing experiments (e.g., in Reddit communities for specific regions or professions) to gauge interest in the unique features.
- Prioritize building one standout smart feature as the next MVP iteration to create a clear competitive advantage.

Market signals
The weather app market is large and growing, with a global valuation of approximately USD 1.003 billion in 2024, projected to reach USD 2.238 billion by 2033, growing at a CAGR of 8.58%. This growth is driven by increasing smartphone penetration, demand for real-time and hyper-localized forecasts, and the integration of AI and machine learning for enhanced accuracy and personalized alerts. North America is a dominant market, holding over 33% share.
What frustrates people
- The app closes every time you go to another app, so when deciding a route you'll need to pull over to re-enter all your info again.
- Was surprised by snow and freezing fog en route, which the app failed to recognize.
- The interface often feels less intuitive than modern driving apps.
- Free version has quite a lot of ads and popups, which can feel intrusive.
- The 'best time to leave' feature has no apparent relationship to anything whatsoever.

µJS, a 5KB alternative to Htmx and Turbo with zero dependencies
I built µJS because I wanted AJAX navigation without the verbosity of HTMX or the overhead of Turbo.It intercepts links and form submissions, fetches pages via AJAX, and swaps fragments of the DOM. Single <script> tag, one call to `mu.init()`. No build step, no dependencies.Key features: patch mode (update multiple fragments in one request), SSE support, DOM morphing via idiomorph, View Transitions, prefetch on hover, polling, and full HTTP verb support on any element.At ~5KB gzipped, it's smaller than HTMX (16KB) and Turbo (25KB), and works with any backend: PHP, Python, Go, Ruby, whatever.Playground: https://mujs.org/playgroundComparison with HTMX and Turbo: https://mujs.org/comparisonAbout the project creation, why and when: https://mujs.org/aboutGitHub: https://github.com/Digicreon/muJSHappy to discuss the project.
