You became an SLP for the therapy. Not the paperwork. SLPcentral is the all-in-one app for speech-language pathologists at every stage of the journey — from undergraduate CSD students logging their first observation hours to licensed clinicians managing a full caseload. Built by an SLP who lived the workload, not a software vendor guessing at it. ONE APP THAT GROWS WITH YOU • Undergraduate students: track your 25 ASHA observation hours, organize coursework, and learn the field with a built-in reference library. • Graduate students: track all 400 clinical hours with disorder-area breakdowns, manage classes and deadlines on a unified calendar, and get help drafting SOAP notes. • Licensed SLPs: manage your caseload, collect live session data trial-by-trial, track IEP goals, and draft progress reports in a fraction of the time. TWO WAYS TO A SOAP NOTE Run live data during the session and let the app draft a note from the numbers — or just talk. Brain Dump lets you describe the session in your own words afterward and drafts the note from what you said. Every AI draft is clearly marked "DRAFT — review before saving." The app assists; you stay the clinician. PRIVACY BUILT IN Client names never touch our servers — they're stored encrypted on your device only. Everything the app sends to the cloud uses random codes, never names. The app supports your HIPAA and FERPA obligations with on-device identity, auto-lock, and de-identified AI. (SLPcentral is a tool that helps you meet your obligations — you remain responsible for compliance in your setting.) LIVE SESSION DATA COLLECTION Big check/X targets, swipe between clients in a group, running accuracy per goal, and an instant progress graph the moment you finish. Designed to be used one-handed, in the room, with a kid in front of you. TRACK THE WHOLE JOURNEY Observation hours, clinical hours, Clinical Fellowship hours (1,260 with the ASHA breakdowns) — the milestones that are scattered across spreadsheets and portals, finally in one place. FREE FOR STUDENTS, ALWAYS Undergraduate and graduate hour tracking is free — no trial, no paywall, no catch. Your 25 observation hours and your 400 clinical hours are yours to track for nothing. SLPCENTRAL PRO — FOR LICENSED CLINICIANS Unlimited caseload, live session data collection, and AI-assisted drafting. • $14.99 per month, or $149.99 per year (about $12.50/month) • 7-day free trial • Cancel anytime in your iPhone's Settings Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel in Settings → Apple Account → Subscriptions. Your data stays yours. If you don't subscribe, you can still read and export everything you've already put in — nothing is locked away. Terms of Service: https://slpcentral.app/more/terms-of-service Privacy Policy: https://slpcentral.app/more/privacy-policy SLPcentral is a documentation and organization tool. It does not diagnose or treat, and AI output is always a draft for your review.
