Trip planning kit: flights, reviews, tickets and itinerary

This set covers a self-planned trip from Vietnam, split across five apps. Vietnam Airlines and Vietjet Air handle flights, as a full-service and a low-cost carrier. Tripadvisor is for reading hotel and restaurant reviews. Klook covers attraction tickets, transfers and eSIM. Google Calendar keeps a shared itinerary for the group. Each app works on its own, so you move details between them yourself.

For

   3. Tripadvisor – Hotel and restaurant reviews

   Free, with over one billion reviews and opinions per its App Store description, plus saved places and group trip planning. Note: fake reviews remain an issue (the company identified 1.33 million fraudulent reviews in 2022), and by the company's own account the "Featured" sort factors in partner payments.
