Our Mission
We're building the infrastructure for reading fluency assessment that classrooms have always needed but never had.
Mission Statement
PhonoFlow's mission is to make reading fluency assessment faster, more accurate, and accessible to every K–12 classroom — regardless of school size, budget, or available support staff. We believe that every student who is struggling to read deserves to be identified early, and every teacher deserves the tools to do that without sacrificing hours of instructional time.
The research on early literacy intervention is unambiguous: the sooner a reading difficulty is caught, the better the outcome. The bottleneck has never been the knowledge — it's been the process. We're here to remove that bottleneck.
The Problem
Oral reading fluency assessment is one of the most evidence-backed diagnostic tools available to a classroom teacher. A standard ORF check — asking a student to read a passage aloud while tracking errors, monitoring pace, and noting fluency patterns — gives a teacher a clear, quantifiable picture of where a student is and where they need to go.
The problem is how it's done. Today, that process looks like this: a teacher pulls one student aside, holds a stopwatch, listens carefully, marks errors by hand on a paper form, calculates words correct per minute, records the score, files the sheet, and moves to the next student. With a class of 25, a full round of ORF assessments can consume an entire week of pull-aside time. And that's before accounting for scoring errors, lost paperwork, or the difficulty of comparing results across weeks and months.
Teachers know the assessments matter. They do them anyway. But the overhead means they happen less often than they should, the data is harder to act on than it needs to be, and the time cost falls entirely on the teacher.
Our Approach
PhonoFlow doesn't try to replace the teacher's judgment — it handles the parts of assessment that don't require it. The stopwatch, the error tracking, the fluency calculation, the record-keeping: these are mechanical tasks that consume time without adding insight. We automate them so the teacher's attention can stay where it belongs — on the student in front of them.
The app uses AI-powered speech recognition to transcribe a student reading aloud in real time, scores word-level accuracy against the reference passage, calculates words per minute, and flags fluency patterns like pauses, repetitions, and prolongations — automatically, in under two minutes. Teachers who prefer to stay hands-on can use Manual Mode, marking errors themselves while the app handles timing and scoring.
The result is the same actionable data a skilled teacher produces manually — just without the hours it used to take to get there. That data is stored per-student on the classroom device, building a longitudinal picture of each reader's progress over time.
Every feature starts with a single question: does this make a teacher's day easier? If the answer isn't clearly yes, we don't build it. PhonoFlow is a tool for teachers, designed around how they actually work — not how a product manager imagines they work.
Student data is sensitive. We treat it that way from the ground up — not as a compliance checkbox. Students are identified by initials only, all assessment data stays on the classroom device, and we collect zero personally identifiable information. FERPA and COPPA compliant by design, not by afterthought.
Oral reading fluency is one of the most researched indicators of reading development in existence. We built PhonoFlow around proven assessment methodology — not novel metrics invented to seem impressive. The Science of Reading is our north star, and it always will be.
The schools that need better assessment tools most are often the ones with the fewest resources. We price PhonoFlow to be accessible to individual teachers, not just well-funded districts, because the literacy gap doesn't care about a school's budget.
Our Vision
Right now, PhonoFlow is in the hands of individual teachers who found us and took a chance on something new. That's where every tool worth building starts. But the problem we're solving isn't small, and our ambition isn't either.
The long-term picture is a world where no student goes unidentified because their teacher didn't have time to assess them. Where reading intervention programs are driven by current, accurate data — not quarterly benchmarks that are already months out of date by the time a teacher can act on them. Where a first-year teacher in an under-resourced school has access to the same quality of assessment data as a veteran teacher with a full support staff.
We want PhonoFlow in every K–12 classroom that teaches reading — not because it's a nice product, but because early identification changes outcomes, and right now too many students are slipping through a gap that better tooling could close.
Every student who is struggling to read deserves to be identified early. We're building the tool that makes that possible at scale.
We're looking for teachers and schools who share this belief. If that's you, we'd love to talk.
