the activities such as visiting meseums or churchs, tour a park, etc. 窮遊行程助手 has a feature that you can select places to visit from a list in a city you visit on a day. You can even have more than 1 cities on the same day (in case you visit 2 cities on the same day). All these places have additional info and user inputed comments and photos to help you make a selection to visit them. 窮遊行程助手 can also optimize the places, automatically or manually, so you can visit them in an efficient order. The problem with 窮遊行程助手 for me is that all the names are in Chinese which makes it difficult to match on the places websites, Google maps, etc. We all know that English is the best language, sometimes the only one, to handle travel.
TripAdvisor has a feature called 'Trips' but I find it very hard to use, if useful at all.
Most travel related apps focus on transportation, lodging, etc but lack a function to handle activities.
Of course, you can rely on the tour books such as Rick Steves' etc. to get all the info. But making an itinerary has to be manually done, e.g. on a spreasheet. A good app should be a better way to do this.
