36 Questions is a free lifestyle app developed by torib.io for Android 9.0. The app is based on a study by Arthur Aron and his colleagues that explores whether intimacy between two strangers can be accelerated by having them ask each other a specific series of personal questions. The app contains 36 questions, broken up into three sets, with each set intended to be more probing than the previous one. The app's goal is to foster mutual vulnerability and closeness between two people.

The app is easy to use and has a simple interface. Once you start the app, you can choose to answer the questions with a friend or a partner. The app provides a timer for each question, and there is an option to pause and resume the exercise. The questions are thought-provoking and require personal self-disclosure, which can be challenging for some users. The app provides an opportunity for users to deepen their relationships and gain insights into their own and their partner's values and beliefs.
