Turn study and reading time into mountain landscapes. Your real records shape a view of what you gave your time to. Cishan combines a study timer, time tracker and reading journal for learning, work and everyday life. Your recorded minutes shape daily and weekly mountain landscapes you can revisit. Start a timer, keep a record, then look back at where your time went. Basic timers and unlimited historical records are free. TIMERS, TASKS AND REFLECTION Start, pause, resume and finish activity timers. Organize tasks, schedules and tags, and keep notes alongside your records. Explore dates, rotate and zoom your mountains, or share a landscape. Review daily, weekly and monthly statistics to understand where your time goes. JOURNAL AND WINDOW SPACES · PRO Keep everyday moments with journal templates, quick notes and a free canvas. Arrange text, drawings, paper and stickers, and link pages to your time records. Creating and editing journals requires Pro. Stickers use your inventory; adding an image sticker consumes a general sticker. Earn resources through real records to redeem buildings and decorations. Pro enables decorating and window views in supported buildings you have redeemed and placed. Choose sounds and weather moods. Pro does not grant every decoration. FREE, PLUS AND PRO Free download with in-app purchases. Free includes 5 active activities and unlimited historical timer records; archived activities do not use an active slot. Plus lifetime expands the limit to 199 and unlocks the Taoyuan ink style. Pro includes Plus, journals, canvases, stickers, advanced markers, decorating and supported windows. YOUR LANGUAGE, YOUR RECORDS Choose from 45 interface languages. No account registration is required. Records are saved locally by default, with manual import and export backups. Plus and Pro can opt into private iCloud sync using your own storage; sync is off by default. Changing language preserves the text you entered. PURCHASES AND SUBSCRIPTIONS Pro monthly, quarterly, yearly and lifetime plans provide the same current Pro features for different periods. Subscriptions renew every 1, 3 or 12 months. Eligible users may receive a 7-day trial only when shown on the purchase page and confirmed with Apple. One introductory offer per person per subscription group; the selected plan charges automatically after the trial. Prices, offers and periods are shown in the app and on Apple's confirmation screen. Cancel in your Apple account's subscription settings at least 24 hours before a trial or current period ends. Deleting the app or buying lifetime access does not cancel an existing subscription. The app provides Restore Purchases and subscription management; purchases and restoration need Apple services. After Pro expires, records and existing journals remain readable and exportable while Pro editing and redemption pause. A valid Plus lifetime purchase remains; otherwise Free applies. You choose which excess activities to archive.
