Bindex Planner brings your paper planner and iPhone schedule together in one place. Beyond managing events and TODOs, it turns your daily progress into books and grows a personal study as you keep going.

On-device OCR reads the text and creates editable event candidates. For monthly-block planner pages, Bindex reads the date grid and turns what you wrote in each day's box into candidates for that day. Pages with an uncertain month are not saved until you confirm the month, and candidates with an uncertain date or time are marked Needs review. Save pending skips them until you tap Mark as checked. • Check and correct candidates side by side with the original photo • Use the import history for each photo to resume unsaved candidates or undo what you saved • Images are not sent to cloud AI. Only after your explicit consent can recognized text be sent to an external AI service to format dates, times, and titles. You can keep processing on device only.
