Online Teaching Tool Selector
Find Your Perfect Free Teaching App
Answer a few questions to get personalized recommendations for free tools that work best for your teaching style.
Teaching online doesn’t need to cost a fortune. If you’re a tutor, a teacher, or just someone who wants to share knowledge, you can start with tools that cost nothing - and still work better than paid options. The real question isn’t whether free apps exist - it’s which ones actually make teaching easier, not harder.
Google Meet + Google Classroom: The Simple Starter Pack
If you’ve ever used Gmail or Google Docs, you already know how to use Google Meet and Google Classroom. They’re built into the same system, so logging in takes seconds. No extra apps to download. No credit card needed.
Google Meet lets you host live classes with up to 100 people for free. You can share your screen, mute participants, and record sessions directly to Google Drive. The recording saves automatically, so students who miss class can catch up later.
Google Classroom ties it all together. You can post assignments, collect homework, give feedback, and grade everything inside one place. It works on phones, tablets, and laptops. Students don’t need Google accounts - you can send them a join code and they’re in. Teachers in UK state schools have been using this for over five years. It’s stable, secure, and doesn’t crash during peak hours.
Microsoft Teams for Education: Built for Schools
Microsoft Teams for Education is another free option that’s quietly become one of the most reliable tools for online teaching. It’s not flashy, but it’s rock solid. If your school already uses Office 365, you’re halfway there.
Teams lets you create class teams, schedule live lessons, and share files like Word docs or PowerPoint slides directly in the chat. You can assign tasks, track progress, and even use built-in quizzes. The attendance tracker logs who joined and for how long - useful if you need to prove participation.
Unlike some apps, Teams doesn’t kick you out after 40 minutes. Free accounts support meetings up to 24 hours long. That’s perfect for full-day workshops or extended tutoring sessions. It also works well on low-end devices, which matters if your students are using old laptops or shared family tablets.
Zoom: The Go-To for One-on-One and Small Groups
Zoom’s free plan gives you 40-minute limits on group meetings - but that’s not a dealbreaker if you plan your sessions right. Most private tutors teach in 30- or 45-minute blocks. Zoom’s interface is simple: click a link, join, and you’re in.
The real strength of Zoom is its breakout rooms. You can split your class into small groups for discussions or peer review, then bring everyone back with one click. It’s ideal for language teaching, group projects, or Socratic seminars.
Zoom also has a whiteboard feature, screen sharing, and live captions. You can enable auto-transcription so students can review what was said. And if you record a session, it saves to your computer or cloud - no extra cost.
Many tutors in Oxford and Manchester use Zoom for private lessons because it’s reliable on slow internet. It doesn’t need high-end hardware. A basic webcam and a quiet room are enough.
YouTube Live: Teach Without a Classroom
What if you don’t need live interaction? What if you want to reach hundreds at once, without scheduling? YouTube Live is free, and it’s been used by teachers since 2015 to broadcast lessons to global audiences.
You can go live from your phone or computer. Viewers can comment in real time. You can pin helpful comments, turn off replies, or moderate questions. After the stream ends, the video stays on your channel. Students can watch it anytime - even months later.
It’s perfect for recorded lectures, Q&A sessions, or demo lessons. You can upload slides, use a green screen, or even add lower thirds with your name and topic. No one else charges you to host this. YouTube doesn’t take a cut. It’s free, public, and indexed by Google - so students might find your lessons even if they’re not looking for you.
Discord: The Unexpected Classroom
Most people think of Discord as a gaming app. But thousands of teachers use it to run online classes. Why? Because it’s flexible.
You create a server. Inside, you set up text channels for homework, announcements, and Q&A. Then you create voice channels for live lessons. Students join when they’re ready. No need to wait for a scheduled Zoom call.
Discord lets you upload PDFs, videos, and links. You can use bots to auto-post daily questions or reminders. It’s great for long-term courses where students need ongoing support. A language teacher in Brighton uses Discord to run weekly conversation circles. Students drop in after school. No login hassles. No fees.
The downside? It’s not designed for grading. You’ll still need Google Classroom or a spreadsheet to track progress. But for community, discussion, and casual teaching, it’s unmatched.
Why Free Isn’t Always Better
Free tools sound great - until you hit a wall. Maybe your video keeps buffering. Maybe students can’t find the assignment link. Maybe you spend more time troubleshooting than teaching.
Here’s what free apps usually lack:
- No built-in attendance tracking
- No automated grading
- No parent notifications
- No analytics on student engagement
That’s fine if you’re teaching five students once a week. But if you’re running a full course with 30+ learners, you’ll need systems. That’s why many teachers start with free tools - then upgrade only when they need more.
Don’t feel pressured to switch. If Google Meet works for you, stick with it. If Zoom gets the job done, keep using it. The best app is the one you actually use.
What Most Teachers Actually Use in 2025
Based on surveys from UK tutors and school networks, here’s what’s working right now:
- 68% use Google Classroom + Meet for regular classes
- 22% use Zoom for private tutoring
- 15% use Microsoft Teams (mostly in schools with Microsoft licenses)
- 9% use YouTube for recorded lessons
- 6% use Discord for student communities
Notice something? Most teachers use two tools together. Google Classroom for assignments. Zoom for live lessons. YouTube for recordings. Discord for chat.
You don’t need one app to do everything. You need a simple system that fits your style.
How to Choose Your Free App
Ask yourself these three questions:
- How many students do you teach at once?
- Do you need to grade or track progress?
- Do your students have reliable internet and devices?
If you teach 10 or fewer students and don’t need grades - try Zoom or Discord.
If you teach 20+ and need to assign work - use Google Classroom with Meet.
If your students are on slow connections - avoid apps that need high bandwidth. Stick with Google or Teams.
If you want to reach people who aren’t in your class - use YouTube.
There’s no perfect app. There’s only the one you’ll actually use.
Can I use free apps for teaching kids under 13?
Yes, but you need to follow COPPA and UK data protection rules. Google Classroom and Microsoft Teams for Education are designed for under-13 users and comply with these laws. Zoom and YouTube require parental consent for minors. Discord doesn’t allow users under 13 at all. Always check the app’s age policy before inviting students.
Do I need to pay for a better camera or mic?
No. Most laptops and phones have decent built-in mics and cameras. You don’t need a $200 webcam. Just sit near a window for natural light, and speak clearly. If your voice sounds muffled, try a free noise-reduction app like Audacity. A $10 USB mic from Amazon can help, but it’s not required to start.
Can I record lessons and sell them later?
It depends. YouTube allows you to monetize your own videos. Google Meet recordings belong to you - you can upload them to YouTube or your website. But if you use Zoom’s free plan, you can’t legally sell recordings unless you upgrade. Always check the terms of service. Don’t assume free means you own the content.
Which app works best on low-end phones?
Google Meet and Microsoft Teams are optimized for low-bandwidth use. They use less data than Zoom or Discord. YouTube videos can be watched offline if downloaded ahead of time. Avoid apps that require constant video uploads or heavy graphics. Stick with text-based tools like Google Classroom for assignments if your students’ phones struggle with video.
What if my students can’t log in?
Use a simple link. For Google Classroom, send a class code - students don’t need to create an account. For Zoom, send a direct meeting link. For YouTube, just share the video URL. Avoid apps that require complex logins or email verification. The easier it is to join, the more students will show up.
