Global calendar-sharing platform TimeTree announced a collaboration with Imagineer's hit puzzle game SUMI SUMI, introducing 15 complimentary character stickers designed to revolutionize how users organize and visualize their schedules. The collection showcases popular San-X characters, including Sumikkogurashi and Rilakkuma, set to roll out on October 2nd.

TimeTree [https://timetreeapp.com] representative explained, "With Sumikkogurashi, Rilakkuma, and other SUMI SUMI characters-that enjoy widespread popularity overseas, particularly in Asia and North America-featured throughout the calendar, it's designed to make the time spent waiting for your next plans something to look forward to."
The user experience prioritizes simplicity and accessibility. Calendar users can integrate stickers by selecting the emoji button within the app's daily view, navigating to the collaboration section, and choosing their preferred character. The one-tap removal feature ensures seamless customization without technical barriers.
TimeTree has established itself as a dominant force in digital scheduling since launching in March 2015, earning recognition as the definitive "wall calendar on your phone". The platform now serves over 67 million registered users globally, demonstrating consistent growth through strategic innovation and market expansion.
The company's trajectory gained significant momentum following a 2.2 billion investment from South Korean telecommunications giant SK Telecom. This funding supports TimeTree's ambitious development of scheduling automation and intelligent calendar assistance through AI agent [https://timetreeapp.com] technologies.
"Our vision extends beyond traditional calendar applications," said CEO Chajin Park. "Through strategic partnerships and technological advancement, we're creating comprehensive scheduling ecosystems that deliver meaningful, personalized experiences for users worldwide."
