GridNote is a weekly schedule and session-notes app for school speech-language pathologists. Try it free for 7 days. After that, unlock once through Apple. The same unlock covers iPhone, iPad, and Mac. Sign in with the same Apple ID and your caseload syncs through that Apple ID’s private iCloud — open a note on your phone, see it on the Mac. If you already bought GridNote as a paid app, you stay unlocked. Keep a color-coded Mon–Fri therapy grid, tap a student to document a session, and track Medicaid-style billing status without sending claims anywhere. SCHEDULE • Monday–Friday lined time grid from about 8:10 AM • Therapy, group therapy, planning, lunch, duty, Child Find, and specials • Tap a day name to mark holiday, no school, out of office, PD, or snow — that date only • Copy a repeating week from another school year • Duplicate a block while editing • A green check means notes or goals are saved; billed is a separate mark SESSION DOCUMENTATION • Date, start/end, minutes, service codes (92507, 92508, Evaluation, Absent, Other) • New notes fill activity and materials from the last matching student note • Goals, notes, materials, and billing: Pending, Billed, No, or NB • Copy notes or Copy for Google to paste into a district form you already use STUDENTS AND BILLING • Caseload pages with IEP goals and session history • End of day: who’s left to bill, plus sessions scheduled with no note yet • History with CSV export Your caseload starts empty so you can add your own students. Open Settings → Load Demo Caseload only if you want a fake sample week to explore (it replaces anything already in this caseload, including other devices if iCloud is on). GridNote does not have its own login. Sync uses iCloud on this Apple ID. It is not a medical device and is not a Medicaid payer connection. Changes save on the device right away, then iCloud syncs when you are signed in.

Verdict
The clearest difference is ads: GridNote SLP at none against Sona's shown. Sona's advantage is ratings volume (9 vs 1) and iOS requirement (15.0 vs 18.0). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Sona sells 3 in-app purchases, starting at $9.99 per month and GridNote SLP sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Sona against 5.0 for GridNote SLP. That said, the two scores are not equally well evidenced: Sona has 9 ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly every 3 days. Both last shipped on October 31, 2026.
