Math and physics for the same student
The subject is set on each lesson: math on Tuesday, physics on Thursday, each lesson at its own rate. The family balance covers both.
- Length and price per student
For science tutors
Software for private physics and chemistry tutors
High schoolers, university and pre-med students, students who also take math with you: one schedule, and who has paid.

Trusted by tutoring businesses
Kadrella is private-lesson management software that fits physics, chemistry and science tutors: weekly lessons per student, the subject noted on each session, small groups and payments tracked per family. Physics is the third most requested tutoring subject in the Les Sherpas 2024-2025 study of French students (7.1% of lessons, after math and French), and many tutors teach it alongside math to the same students. Kadrella has no simulations or problem sets: it runs the organisation and the money.
What Kadrella does for a science tutor
Your week in Google Calendar
Your lessons sync to Google Calendar with the student, subject, place and length (Essentials plan).
Who has paid this month
Each lesson taught adds to what the family owes, each payment you record brings it down, oldest lessons first. Late payers stand out, and the reminder goes out on WhatsApp when you click (Essentials plan).
Bank transfers matched
Connect your bank account read-only: Kadrella recognises a transfer from a student or their parent and links it to the right record (Complete plan).
One rate for high school, another for university
Price is set per student, by the hour or per session: a high-school junior and a first-year engineering or pre-med student do not pay the same.
Revision before the exams
Before end-of-year exams, add extra sessions with an end date, one to one or in a small group, each student with their own price.

The founder's story
Built by a teacher, for his own tutoring business.
I've taught maths and computer science since 2020, and I run my own private-tutoring business, Head of Science: several teachers, around a hundred students. I'm also a software engineer. In 2024, I started building this tool for myself, because tracking payments and chasing late ones took every Sunday. I've used it every day since. Kadrella is that same tool, opened up to other teachers.
Frequently asked questions
Does it work for biology or engineering tutors too?+
Yes. The subject is a free field on each lesson: physics, chemistry, biology, engineering or math, Kadrella handles the lessons the same way.
Can I tutor university or pre-med students?+
Yes. A university student is a student like any other: no linked parent if they pay for themselves, with their own rate and slots.
Does Kadrella include problem sets or simulations?+
No. Kadrella runs the organisation side of your lessons: schedule, students, families and payments. Keep your usual tools for exercises and simulations.
How much does it cost?+
The free plan covers students, lessons and payment tracking with no limit. Essentials (€29 a month) adds WhatsApp, Google Calendar, Superprof and Discord; Complete (€49 a month) adds invoicing, bank reconciliation and reports. No commission on your lessons.
Do lesson reminders go out automatically?+
No. When you create a lesson, Kadrella can send a confirmation on WhatsApp. It does not send an automatic reminder before each lesson, and payment reminders go out when you click.
