How Once compares to other early-reading programs

Most reading products are apps kids use alone. Once is the only program where a grownup teaches a child to read one-on-one, using a scripted, Science-of-Reading curriculum — about 15 minutes a day. Here's an honest look at how it stacks up.

What makes Once different

  • Scripted so any grownup can teach it — no training, no lesson prep, ~15 minutes a day.

  • ESSA-tiered evidence from real classrooms — not just app-store ratings.
