Keep your favorites' schedules, anniversaries, merch, spending, photos and notes together. Oshi Fan Log organizes your fan life separately for each favorite, without requiring an account. FROM OFFICIAL NEWS TO YOUR CALENDAR Search with your favorite's name, open an official page and register it there. Add more than one official source when needed. Read updates the app can extract from those public pages. Turn an announcement into a calendar entry with its title, event dates and venue. Review the details and add it to the app's calendar or your iPhone calendar. Multi-day events support start and end dates. You can also create a draft from an announcement image or text. Reading depends on the page's structure and public availability. Missing dates need to be entered manually. Check the original announcement for changes or cancellations. The app does not retrieve every social media post or guarantee real-time updates. SCROLL THROUGH YOUR FAVORITE'S ROOM Read content, schedules, acrylic stands, merch, places, photos, posts and links in one vertical flow, or jump with the bottom menu. Official announcements and media news have separate sections. SEE WHAT'S COMING UP Home focuses on nearby dates, including yesterday. Change the date range to look further ahead. Save concerts, streams and releases, track birthdays and debut dates, and count the days since you became a fan. Widgets and Apple Watch keep important dates close. VIDEOS, LINKS AND MEMORIES Register supported video and streaming channels and social profile links. Available content depends on the service and settings. Organize your collection, wish list, expenses, photos and private notes. Save meaningful places on a map or make a digital acrylic stand from a photo. COMMUNITY Read and post short messages with fans of the same favorite. Public posts include report, block and delete-own-post controls and are separate from private notes. PLANS • Free: register up to 2 oshi. • Premium: register up to 30 oshi and expand eligible limits. Monthly and yearly localized prices are shown before purchase.
