Hangzhou G20 plans to go out and relax. Is there any good travel app? Give me a recommendation

In addition to regular detailed explanations of attractions and routes, the "Yilu Le Travel" platform uses the new smart tourism concept of Internet + tourism to give this traditional scenic spot a completely different travel experience. The positioning of the mobile phone is combined with a new purely hand-drawn digital map, which is extremely accurate; at the same time, the goddess-level automatic voice explanation can guide you wherever you go, making it an exclusive real-person voice assistant for tourists. The cute mascot and the exquisite and intuitive interface also add a lot of points to the product.
