Built for educators

Every student
deserves to be
called on fairly.

Roollo uses equity-weighted selection so quieter students are heard as often as the eager ones. Classroom fairness, by design.

The Toolkit

Everything you need
for fair participation

Designed with equity at the core — not as an afterthought.

Equity-Weighted Roll Call

Students called less recently have a higher probability of selection. The algorithm tracks and balances participation across every session.

Smart Group Generation

Generate balanced groups using performance level, ELL, and SEN data — or go fully random. Fully your call.

Analytics Dashboard

Track your Gini coefficient, coverage, and fairness trends over 7 days, 30 days, or a full semester.

Live Check-In Sessions

Students join via QR code on any device. Take attendance and see who's present — in real time.

The Flow

Set up in minutes.
Use it every day.

01

Create your class

Add a class name, meeting days, and your roster. Optionally tag students with performance levels, ELL, or SEN flags for smarter grouping.

02

Run Roll Call or Groups

Tap Roll Call for equity-weighted selection, or generate balanced groups. Mark absences first — only present students are included.

03

Track over time

Analytics show your fairness trends and which students need more attention — across every class, across the whole semester.

stays on your device.

  • No advertising, no analytics tracking, no data sold — ever
