There's a thing in Canvas that you can use that is really not user friendly. I am going to share this with my other professors because this is what you want. This is easy.

What teachers love

Everything you need to run your school year smoothly

Built around what actually happens in your classroom from the first bell to the final report.

Attendance in 30 seconds

The whole class checked in before you finish writing the date on the board.

No app download for students

Students scan a QR code with their phone camera. No account. No install. Nothing to explain.

Students can't sign in for their friends

Rotating QR codes, location, time, and device restrictions mean only the student who showed up gets marked present.

Every student's full history

“Was Maya here on March 5th?” Three seconds. Not three notebooks.

Set it once for recurring classes

Daily, weekly, or custom schedule. OneTap auto-creates each session. You never touch it again.

Your roster imported in 2 minutes

Paste from Excel, upload a CSV, or type names in. Done before the bell rings.

iPad kiosk at your classroom door

Set up any tablet as a self-check-in station. Students tap their name as they walk in. Works even if your school locks up phones.

Every class in one dashboard

Period 1, Period 3, after-school. Each with its own QR, roster, and history. One system.

Reports admin actually accepts

Download by student, by date, or full roster. Excel, CSV, or PDF. One click.

Photo at check-in & check-out

Students snap a photo when they scan. Proof of presence. No more “I was there, I swear.”

Invite co-teachers to your account

Add colleagues so they can take attendance for their classes too. Everyone sees the same records in real time.

Connects to tools you already use

Zapier, Jotform, and custom API for custom setups. Sync attendance data wherever you need it. Available on paid plans.

AI-powered attendance insights

Ask a question. Get the answer. No spreadsheets.

Connect OneTap to ChatGPT or Claude and just ask, “Who's been absent this week?” You get an instant answer from your own live, timestamped attendance data. No dashboards, no exports.

Teachers say OneTap changed their day.

I got 5 minutes back every single class period. That's a full week of teaching over a year.

Before you sign up

Questions teachers ask.

Is it really free? What's the catch?

Yes. Track your first 100 students free forever if you sign up before Sept 1st. No credit card required. No trial expiration. No hidden fees.

Do students need to download an app?

No. Students scan a QR code with their phone camera (works on any phone, no app), or tap a kiosk you set up, or you scan their student ID. Zero downloads for students.

My school locks up student phones. Does this still work?

Yes. Use the Self-Check-In Kiosk mode on your iPad by the door. Works perfectly with strict phone policies. Or students can scan their unique QR passes or student IDs.

What if a student doesn't have a phone or forgets it?

No problem. You can check them in from your admin dashboard in OneTap. Or use the kiosk mode or student ID scanning. Every method works.

Do I need IT approval or an admin to sign me up?

No. Setup takes only 5 minutes. You don't need to integrate with anything to start tracking class attendance.

What about my school's Canvas, PowerSchool, Google Classroom, or SIS?

Yes! You can instantly export your OneTap attendance records as a CSV formatted perfectly for a 1-click upload into Canvas, PowerSchool, or Google Classroom. For advanced users, you can also fully automate syncing via Zapier or custom API.

What if I have more than 100 students?

If you sign up before September 1st, your first 100 students are free forever. If you are teaching more than that, our paid plans start at $49.99/month (billed annually). Tip: don't pay out of pocket. We have a pre-written template you can use to ask your school admin to cover your subscription.

Can I share OneTap with other teachers at my school?

Yes. Share the link and every teacher at your school gets their own free account. Want your whole team working from one shared dashboard? You can invite up to 3 co-teachers on a single account, and everyone sees the same rosters and check-in data in real time.

How do I export attendance for report cards, conferences, or admin?

Open your dashboard, pick the class and date range, and hit download. You get a clean Excel, CSV, or PDF with every student's name, check-in time, and total attendance, ready to hand to admin or drop into your report card system. Takes about ten seconds.

Is my student data safe?

Yes. Your student data is completely safe and private. We use industry-standard encryption hosted in secure US data centers, and we never sell your data to anyone.

Starting September, no more paper.

Start this school year without a single paper roster.

Set up your class in 5 minutes. Students scan a QR code on the way in. You start teaching. That's it.
