What parents say about our awesome apps:
*** 5 stars! Brilliant! An app that understands how kids actually learn. Thank you!

Reading Fluency Builder provides:
- Graduated practice starting with simple texts and slower speeds.

- Students can practice with multiple texts per level.
- 'At a glance' reporting shows you instantly how your learner is progressing.
- Audio support is provided so learners can hear a fluent model.

- Incremental levels take a student from mid Grade 1 reading speed up to mid Grade 5 reading speed.

Our app is based on proven research on the effectiveness of modeled and repeated reading to increase fluency -- but we make it fun!

Great app

Great app but I wish the upgrade was cheaper or that more levels were offered for $8.99.

Limited, expensive upgrade

There are only 4 free levels which took my 7 year old daughter less than 5 minutes to complete. I’m guessing it would take her about 30 minutes to complete the next 26 levels and the upgrade costs $8.99. I would consider the upgrade if it was $.99 or offered a couple hundred levels for the $8.99. Not a good value!

I really like this app and it helps with my reading skills but there are only 30 levels and when I got to the end I didn't know what to do and I don't know what to do with my coins either
