Devices
Phone, tablet and computer, the same data.
For instructors of driving, dance, maths, piano and everything in between.
Lessons, hours and students work the same way, whatever you teach.
One working day
This is eInstruktor on a real day, from the first lesson to the last message.
07:30
The morning starts with your schedule.
The week on a single strip, lessons by the hour and days off marked. Book a new lesson in a few taps, with the student already filled in.
11:15
After the lesson, two sentences.
Note down what you covered and what comes next. The hours add themselves up, so you always know where each student stands.
15:40
Student running late? Get in touch in one tap.
From the student's card, start a call, a text or a WhatsApp message in the right app. No looking up the number, no copying it out.
21:00
In the evening, ask instead of searching.
The assistant knows your schedule and your students. Ask who's on tomorrow or how many hours Ana has, and the answer comes straight away.
And everything between lessons.
Practice, exams, deadlines and your time slots, in the same place as your schedule.
Practice in folders
Group exercises into folders, each with four steps. See at a glance how far each student has got.
Ready for the exam
Before you register, see whether everything is in place: items, payment and hours.
Deadlines on time
The app warns you before a licence or a registration expires.
Your time slots
A 45-minute school period or a full hour. The times you use most are waiting for you in the schedule.
