## What is Fluency Tracker?

Measure stuttering accurately — live %SS, SPM, and severity in a tap-friendly fluency tracker.

FluencyTrack is a stuttering calculator for speech-language pathologists and parents. Count syllables and disfluencies during a speech sample, then get the numbers clinicians actually use: percent syllables stuttered (%SS), syllables per minute (SPM), stuttered words per minute (SWPM), and automatic severity.

WHY SWITCH
Older stuttering calculators freeze, lose the session, and sometimes report 100% stuttered syllables. FluencyTrack counts a disfluent syllable as a syllable automatically (no double-tap), supports undo, and saves every session.

FOR SPEECH-LANGUAGE PATHOLOGISTS
• Simple mode: Syllable + Disfluent for fast live counts
• Detailed mode: six clinical disfluency types — part-word repetitions, whole-word repetitions, prolongations, blocks, interjections, revisions
• Client profiles and session history
• %SS trend charts, speaking rate, and disfluency breakdown
• Timer presets (3, 5, 10 minutes) plus unlimited
• PDF reports and CSV export

FOR PARENTS
Track your child’s stuttering severity between clinic visits. Two-button simple mode, a live severity badge, and a history you can share with your SLP.

RESULTS
• %SS — percentage of stuttered syllables
• SPM — syllables per minute
• SWPM — stuttered words per minute
• Severity: Normal, Borderline, Mild, Moderate, Severe

Built for iPhone and iPad. Dark mode and VoiceOver. No account required — speech samples stay on your device.

FluencyTrack is a fluency measurement tool, not a stuttering therapy or DAF app.
