How Custly solves student tracking problems

Balance disputes

A clear ledger keeps remaining credits visible for both tutor and family.

No network during lessons

Offline usage lets you update the record even when the connection is unavailable.

Scattered records

Keep every note, deduction, and package change in one timeline.

Hard to scale across devices

Sign in and sync data to the cloud when you work from more than one phone.

A Better Routine for Lesson Tracking

1. Start with the package

Enter the student package once so the lesson credits tracker always starts from the right number.

2. Track tutoring sessions after each class

Mark each completed lesson immediately so the student lesson tracker stays accurate and current.

3. Use the record to plan next steps

Review the history before every new lesson to prepare materials, follow up on goals, and reduce missed details.
