About

Kneeboard Plus

Features
Read full description

Kneeboard is the training-record app for independent flight instructors and their students — now covering every rating from Private through Commercial and Multi-Engine, not just Private Pilot. After a lesson, just talk through how it went — Kneeboard's AI turns your spoken debrief into a structured record: skills practiced, proficiency, areas to improve, and homework, mapped to the FAA ACS for the rating you're actually training. Review and edit before it's ever saved. Your student sees their progress the moment you save it. BUILT FOR THE SOLO CFI, NOT A FLIGHT SCHOOL No scheduling software to learn, no institutional bloat — just the loop you already run every lesson, made effortless. NEW IN 2.0 • Instrument, Commercial, and Multi-Engine training, alongside Private Pilot — each with its own FAA-ACS-sourced skill catalog and ground-school topics. A student can train multiple ratings at once; you pick which rating a lesson or debrief is for. • Endorsement tracking — practical-test endorsements, plus recurring currency items like the IPC and flight review, with a "valid until" date. • Redesigned for iPad — a real sidebar-based layout (not a stretched iPhone screen), full-width tables, and working landscape orientation, alongside the existing iPhone experience. EVERYTHING FROM BEFORE, STILL HERE • Voice debrief → structured record. Speak naturally; Kneeboard extracts skills, proficiency, and homework. • A record that travels with the student, not the instructor — students keep their history across every CFI they train with. • Ground lesson & flight scheduling between you and your students, with a day-at-a-glance timeline. • Shared resources — hand students docs, videos, and articles right from the app. Kneeboard is not a flight-school operations platform. It's the simplest way to make every debrief count, across every rating you teach. Terms of Use: https://kneeboard-legal.pages.dev/#terms Privacy Policy: https://kneeboard-legal.pages.dev/#privacy
