About

Study Coin (4174d1)

Read full description

Turn study time into coins and build a steady learning routine. Study Coin combines a timer, daily plans, subject records and an adventure through 30 worlds. Choose a subject and an optional goal task before timing. Review study time, net coins and colored breakdowns by week, month or year. Daily goal tasks award a total of 2,000 coins when all are completed; otherwise the total penalty is prorated, up to 4,000 coins. The Want/To Do balance bonus is settled after the day ends. Explore ten study-item types: a basic boost that grows with your adventure and nine conditional rewards. See each effect before using it, and reserve owned items to activate in sequence. Item bonuses do not stack with morning or scheduled bonus time. Previously owned items and records remain available. A free daily ten-draw shows its odds and final-slot guarantee before drawing. Coins and items have no cash value and cannot be bought for money, transferred or redeemed. No paid extra draws. Connect with mutually approved friends and choose what to share. View study minutes, earned coins and detailed coin breakdowns directly in the timeline. Includes optional photos, 24-hour stories, text posts, replies, likes, reposts, reporting, muting, blocking and account deletion. There is no public feed or private messaging. Optional Screen Time features use Apple's permissions to shield selected apps or websites and exchange earned study coins for access time. Targets and Screen Time records stay on the device. The core study features work without Screen Time permission or an account. The National Study Cup and study-coin score use the same illustrative distribution of one million fictional participants. They are not real national rankings or measures of academic ability. Supports iPhone and iPad, including landscape and Split View. Live Activity displays session time, subject and coins; coin updates may pause when iOS suspends the app. Study history, coins, plans and inventories remain local. Using the same Apple-linked friend account on two devices does not merge study data; shared aggregate stats reflect the last device synced. No advertising, tracking, in-app purchases or subscriptions.
