We've reached hundreds of thousands of teachers!
After 50 days of daily videos we've gained 110,000 followers and 8 million views, we now have 31 free apps for teachers, and we want to bring the 2027 EdTech-a-thon to your city.

Hi there,
It’s Duncan from teacher.dev. If you’re a new subscriber, nice to meet you! We’re so excited to have you here. Elliot and I are the development team behind teacher.dev where we build free apps for teachers every day.
We’ve reached hundreds of thousands of teachers
Since September 1st, Elliot and I have posted one video about an app for teachers every day. Over the past 50 days, we’ve gained 110,000 followers across our social media channels and our videos have been viewed over 8 million times. While it’s still strange to know that so many people have seen our faces 😅, we’re so grateful that we’ve been able to reach this many teachers. We could not have done it without all the support we’ve received from you all.
We now have 31 free, publicly-accessible apps for teachers
From Shy Safari, a gamified classroom noise monitor, to Class Grocery, a simulated grocery store, we’ve released a wide range of apps. You can check out all of the apps we’ve released at teacher.dev/apps, and submit new ideas to teacher.dev/ideas.
Our craziest idea yet
In July, we hosted the 2026 EdTech-a-thon in Atlanta, Georgia. We brought together 50 teachers and developers to build practical tools for teachers. Many of those tools became the basis for the apps we’re releasing now!
As we started brainstorming for the 2027 EdTech-a-thon, we wrote down two priorities: 1) bring people together in-person and 2) make it accessible to as many teachers as possible. We realized that hosting one event in one place simply wouldn’t cut it.
Instead, we want to bring the EdTech-a-thon to you. From June to August 2027, Elliot and I will travel to different cities, running free, one-day events where teachers come together to share ideas, learn from each other, and design tools that actually make their lives easier. We’re not sure of our route or the scale of this endeavor, but we’ll need to collaborate with local teachers to find meeting space in a school or library. If you want to help us bring the EdTech-a-thon to your city, reply to this email! We read every reply.
Have a great month!
Duncan, Elliot, and the teacher.dev team
