Company profile

researched Aug 2026

Candle is a consumer mobile application positioned as a shared "home" for a romantic relationship, combining conversation prompts, games, planning tools and a private archive in a single product. Its core loop is a daily activity: mini games, deep questions and drawing challenges that both partners complete and then compare, intended to take roughly five minutes a day.

Beyond the daily prompts, the app includes weekly date ideas, a shared bucket list, and a private space for saving photos and memories. A second feature set targets partners who are physically apart: lock-screen widgets for sending love notes, photos and reminders, a live countdown to the next time the couple will be together, doodles, and a "thumb kiss" interaction. The company states the product is also used by friendships, not only romantic couples.

Business model

Consumer mobile app distributed through app stores, with a free entry point ("Free to start") and onboarding described as taking 60 seconds.

Traction

The website reports more than 1 million couples and friendships using the app and an average rating of 4.82 stars, with testimonials from users reporting daily use over periods of three to six months.
