Ganjiang Timer is a study timer and study-management tool for students, parents and teachers. It records the study process and turns it into time data and reports, so you can see exactly where the time went. · Exam timing Time each question, grouped by section and sub-question, with configurable section count and a countdown limit. Skip a question, mark it done, or finish early — then get an automatic time report. You can record scores, share the report with teachers and classmates, and print a time label. Retakes and renaming are supported. · Free practice Practise any subject or question type with timing, and get a time report. Custom frameworks are supported, with nine built-in preset frameworks for the Chinese college entrance exam. · Study plans Break the day's work into large and small tasks and time each one as you go. When you finish, you get a "working time / idle time" breakdown showing the split between focus and drift. Built-in templates are organised by school stage and subject, and you can save your own. Batch-adding tasks is supported. · Pomodoro Focus, short break and long break modes, with goals and bonus rewards. · Dictation and spelling Chinese dictation includes the standard character, vocabulary and classical-poetry lists; English covers word lists from multiple textbook editions. Questions are read aloud, each word is timed, and any wrong or timed-out word goes automatically into a wrong-word book for repeated practice. · Reading log Pick a book and start timing; duration and page numbers are recorded automatically. Several books can be tracked at once. · Data and reports Today, this week, this month, this year and all-time study totals, plus subject breakdown, streaks and badges. A study report can be turned into a QR code and shared with your family. · Roles Switch between student, parent and teacher. Teachers can import a class list and compare questions and time; parents can follow their child's records. · Family sharing One family card. Up to 4 phone numbers (including the main card) can be used together, all seeing the same profiles and records. One phone number can be used on up to 3 devices at the same time; membership follows the account, so you don't pay again when you switch devices. · Pricing All timing, planning, dictation and reading features are available, local features work without an account, and there are no ads. Membership unlocks the full history (without membership the last 7 days are kept), saving your own exam frameworks, and cloud sync — so your profiles and records are still there on a new device. Membership is an auto-renewable subscription with monthly, quarterly, semi-annual and yearly options; each option's price is shown on the in-app purchase screen. The subscription renews automatically 24 hours before the end of the current period at the same price, unless auto-renew is turned off at least 24 hours before the end of the current period in Settings > Apple ID > Subscriptions. You can cancel any time; after cancelling, your benefits remain until the end of the current period. Purchases can be restored with "Restore Purchases". Available in Chinese and English.
