Show HN: 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! https://navimodo.com/ April 6, 2026 at 08:58PM

Show HN: A reasoning hierarchical robotics pipeline you can run in the browser This demo combines the flexible task programming and reasoning of Gemini ER (what is the scene, and what should I do?) and classical camera calibration, kinematics, motion controllers. Each layer is independently swappable, and the AI model doesn't need to know anything about the robot's embodiment. This recreates the modularity of a Sense-Plan-Act architecture while retaining the semantic reasoning of a foundation AI model. A writeup explaining the tradeoffs is linked from the page https://ift.tt/3sQPgRD . https://avikde.github.io/vla-pipeline/ April 8, 2026 at 12:35AM

Show HN: Finalrun – Spec-driven testing using English and vision for mobile apps I wanted to test mobile apps in plain English instead of relying on brittle selectors like XPath or accessibility IDs. With a vision-based agent, that part actually works well. It can look at the screen, understand intent, and perform actions across Android and iOS. The bigger problem showed up around how tests are defined and maintained. When test flows are kept outside the codebase (written manually or generated from PRDs), they quickly go out of sync with the app. Keeping them updated becomes a lot of effort, and they lose reliability over time. I then tried generating tests directly from the codebase (via MCP). That improved sync, but introduced high token usage and slower generation. The shift for me was realizing test generation shouldn’t be a one-off step. Tests need to live alongside the codebase so they stay in sync and have more context. I kept the execution vision-based (no brittle selectors), b...
