About ClassDojo

This is the app a large share of American primary teachers use to run a room and reach families: attendance, a random student picker, a group maker, timers, and a class story where the day's photos collect comments and a view count. Messaging works without anyone handing over a phone number. The paid tier runs $7.99 to $10.99 a month, and the sharing list is long for a school app.

ClassDojo Review: Class Story Free, Plus From $7.99

The Toolkit Is the Working Half

A homeroom opens as a grid of monster avatars with the register attached, and three controls across the top: Random, Select and Attendance. Below sit groups and a toolkit — a timer, a group maker, a randomiser, Big Ideas, and Dojo Islands, the play-based world children can enter from home. The appeal for a teacher is compression: picking a pupil, splitting the class into teams and taking the register all happen on one screen, in the twenty seconds that exist between one activity and the next.

Messaging Without Anyone Sharing a Number

Class Chat carries the whole parent group and separate threads carry one family each, both inside the app, so a teacher's personal number never enters the arrangement — the reason many schools adopted it over a class group on WhatsApp. Class Story publishes photos and videos to families with likes, comments and a view count on every post, so a teacher can see that twelve people actually looked rather than guessing. Both sides get reactions and stickers, which sounds trivial until you notice it gives a parent a way to acknowledge a message without starting a conversation at 9pm.

What Plus Costs and What the Data Card Lists

Teachers and families use it free; the Plus tier is billed between $7.99 and $10.99 a month, or $39.99 to $69.99 a year depending on the plan, with a separate Dojo Sparks purchase at $9.99. Google Play records device IDs, crash logs, approximate location, names, email addresses and in-app messages among the data shared with other companies, and Apple's label names advertising and analytics among the purposes. That is a long list for a platform whose subjects are children, and it is the reason for the privacy score below. 50 million installs, 4.8 stars from 1.32 million reviews, 209.9 MB.

Verdict

For a primary teacher this is the strongest free set of classroom tools on a phone, and the messaging design — no numbers exchanged, reactions instead of replies — solves a real problem schools had. The reservation is the data card: names, email addresses and in-app messages shared with other companies is a lot to accept in a product built around children. Worth using; worth reading the privacy settings first.

Core function8.5Register, grouping, timers, stories and family messaging all in one place.

Ease of use8.5Built for a teacher standing up: three taps for the register, one for a picker.

Monetisation7.0The core is genuinely free, with Plus at $7.99 upward and a $9.99 extra.

Performance7.5209.9 MB, and the animated island world is heavier than the classroom tools.

Frequently asked questions

Is ClassDojo free for teachers?

Yes. The register, groups, timers, class story and all family messaging cost nothing for teachers, pupils or parents. The paid Plus tier adds extra tools for a monthly or annual fee, and a separate purchase covers items inside the children's world, but neither is needed to run a classroom.

What is in the classroom toolkit?

A timer, a group maker, a randomiser for picking pupils, a Big Ideas prompt set and the Dojo Islands world children join from home. Attendance, random selection and manual selection sit above them as buttons, so the whole set is reachable from the class grid itself.

What does the paid tier cost?

Plus is billed between $7.99 and $10.99 a month depending on the plan, or $39.99 to $69.99 for a year, and a Dojo Sparks purchase costs $9.99 separately. US prices, subject to change. Nothing in the free classroom tools stops working if a subscription lapses.

Do parents have to share a phone number?

No, and neither does the teacher — that is the point of the design. Messages travel inside the app between accounts, so a class conversation never puts a teacher's mobile number in forty parents' contact lists, and a parent leaving the school simply loses access to the class.

What are the alternatives?

Seesaw covers the same primary-school ground with more emphasis on pupil portfolios. ParentSquare works at district level, with forms and payments rather than classroom tools. Google Classroom handles assignments well but has nothing equivalent to a register, a timer or a photo story for families.
