What are the necessary mobile APP software for traveling to Taiwan?

Actually, I don’t think any APP is needed. I remember when I went to Taiwan for a free trip in 2011, I brought a feature phone and the SIM card I bought didn’t have Internet access. I used the computer every night to check information and make a rough itinerary. If it didn’t work, I would ask the hotel staff or B&B owner, or even I just go to a small shop on the street and ask the clerks or passers-by, and they can give me many good recommendations. If I couldn't find the way, I asked people along the way, and everything went smoothly. Anyway, there is no language problem at all in Taiwan. Of course, if you go to Taiwan now, you will definitely bring your smartphone and activate the Internet function. After all, it can still make the journey much more convenient at critical moments. In my opinion, the only indispensable APP is Google Maps. If you can't find a way to rely on it, it's basically no problem. It can also plan reasonable routes and transportation methods, which can solve most problems.

In addition, you can consider the next travel APP so that you can have a general understanding of where you want to go. For example, Qyer.com can give good recommendations. In addition, although it is not essential, you can download UBER to take a taxi when needed, and use AIRBNB to find B&Bs. At that time, I basically found B&Bs on Taiwan B&B, which is very convenient, but I am not sure if there is an APP that can be downloaded. There is also the Taipei Metro (MRT), which makes it easy to find subway routes in Taipei. Travel Taiwan, according to the introduction on the APP STORE: It is a guide program for free travel to Taiwan provided by the Tourism Bureau of the Ministry of Transportation and Communications. The tour content includes information on food, accommodation, attractions, businesses, etc. And combined with augmented reality (Augmented Reality) to provide direction guidance and path planning. So I believe it will be helpful on the journey. But I still think that asking B&B owners or local people and other donkey tours is more useful than any APP.
