Planning a day trip in China is hard. Every travel blog gives you a list of attractions but never the optimal order. Wander China solves this: select your attractions, and the app uses a nearest-neighbor TSP heuristic to calculate the shortest walking route with time estimates. → 17 cities covered → Tourist mode + Expat mode (local spots most visitors miss) → No signup, no tracking, runs entirely in the browser → Free forever

Hey PH! Maker here 👋 I built this after a frustrating trip to Chengdu – I spent 30 minutes Googling "best order to visit attractions" and got nothing useful. Every list was just... a list. So I built a solver. You pick the attractions, it runs a TSP (Traveling Salesman Problem) heuristic and spits out the optimal walking route with time estimates. A few things I'm proud of: – Expat mode: local spots that tourists usually miss – Changsha has the deepest coverage (my personal test city) – Zero backend, zero tracking, works offline after first load Currently 17 cities. Would love to know which city you'd want added next – I'll prioritize based on the comments here. Happy to answer any questions about the TSP implementation or how I structured the city data.

Love the no-signup browser-only approach, feels like exactly the kind of frictionless tool you'd actually reach for while wandering around a new city.
