Dersim keeps a private tutor's lessons, students and payments in one place. Whether you teach music, languages, maths or anything else: who has a lesson when, who paid what and who still owes you — all at a glance. SET YOUR SCHEDULE ONCE • Add a student, pick their weekly days and times, and the lessons create themselves. • See every lesson in daily, weekly and monthly views. • Reschedule, cancel, or add a make-up lesson at the end of the package. WORK WITH PACKAGES • Define packages like "8 piano lessons" and assign them to students. • See instantly how many lessons are done and how many are left. • When a package ends, "Renew package" sets up the next one with the same days and times. • Add an extra lesson to an existing package and set its price yourself. NEVER MISS A PAYMENT • Record payments; the balance due is calculated for you. • Payment Summary: what you earned this month, what you're owed in total, and by whom. • Prices are shown in your own currency. REMINDERS • Automatic lesson reminders for your students. • Weekly automatic payment reminders. • Ready-made message templates for WhatsApp or SMS. • A morning summary of the day's lessons. YOUR STUDENTS CAN JOIN TOO • Students can sign in to see their lessons, the materials you share and lesson notes. • A Q&A thread for every lesson. Also: today's lessons on Apple Watch, a teacher community, and an app in English, Spanish, Ukrainian, Greek, Russian and Turkish. START FOR FREE Free for up to 10 students and 10 packages.

Lessonday

Lessonday is the planner for people who teach on their own. Paste the message you were sent: the date and time are read on your iPhone and filled in for you, and a student you already have is matched by name. REMINDED BEFORE, NOT AFTER Every lesson reminds you before it starts, with time to get there. See what is next the moment you open the app: who, when, where, and what you planned to cover. THE ADDRESS IS ALREADY THERE Each lesson keeps its own address, and the places you already teach at are one tap away when you book the next one. Open a lesson and get directions to it without typing the address again. THE MONTH ADDS UP Hours taught, what they came to, how many students you are actively seeing, and how it is all trending. WHO TO BOOK NEXT Lessonday sorts your students by who you have not taught in the longest, so the ones quietly going cold surface before you notice they are gone. ONE RATE, OR AS MANY AS YOU NEED Set what you charge once and every lesson picks it up. Charge differently for a subject or for a student, and the more specific rate wins. Student beats subject beats default. WHATEVER YOU TEACH Thirty-eight subjects across nine kinds of teaching: music, sport and fitness, academics, language, martial arts, dance, arts and crafts, tech and mind games. Anything missing, you add in a moment and it behaves exactly like the rest. ON IPAD AND APPLE WATCH On iPad, your lessons and the one you are looking at sit side by side. On Apple Watch, raise your wrist for today's lessons and what you planned to cover, and tap once for directions. Your next lesson can sit right on the watch face. NO ADS, NO ACCOUNT, NO SIGNAL NEEDED There are no ads in Lessonday and nothing to sign up for. Your lessons and students live on your iPhone, so it opens instantly and never waits on a connection. Everything is also kept in your own private iCloud database, tied to your Apple Account rather than to us: we run no server that holds your records, and no account here can read your students' names. Sign in on a new iPhone and years of teaching are already there. It is a notebook for your own teaching, not a platform your students log into. Open it, teach, close it. Your week is already written down.
