PartFive is built for the independent flight instructor — the CFI who runs their own training business, keeps their own records, and answers to their own standards. Everything you need to take a student from first lesson to checkride, on the ramp and in your pocket. STUDENT PROGRESS Every student's journey toward their certificate or rating, at a glance. Progress rings show where they actually stand against the syllabus, what's next, and who's overdue for a lesson. No spreadsheets. LOGBOOK Log a flight or ground session in seconds — dual, solo, PIC, landings, conditions. Your own flying counts too. Import an existing logbook, or export it to ForeFlight or a spreadsheet whenever you want. Your records stay yours. ENDORSEMENTS Issue and track endorsements with expiry dates, so nothing lapses quietly before a checkride. LESSON PLANS & SYLLABI Build a syllabus, plan a lesson, and share it with your student before they get to the airport. PREFLIGHT RISK PAVE assessments before the flight, and safety reporting when something needs writing down. SCHEDULE See what's on today, log a flight the moment it happens, and keep the calendar honest. GET PAID Send a payment request and collect the fee for a lesson right from the app. No invoices to chase. MESSAGES & DOCUMENTS Message your students directly. Share a syllabus, an ACS extract, or a photo of a whiteboard — with one student, or the whole roster. TOOLS & WEATHER Weight and balance, crosswind, fuel, and current conditions where you fly. BUILT FOR THE JOB Dense, readable, glare-friendly screens designed like avionics, not a toy. Dark and light. iPhone and iPad. SUBSCRIPTION New instructors get 30 days with everything unlocked. After that, keep a free tier for your own logbook, schedule, weather and PAVE preflight risk assessment — or subscribe for students, messaging, shared documents, Weight & Balance tools and AI assist. Your data is always yours to export. PartFive works alongside the PartFive web app — the same account and the same records, wherever you are.

Verdict
The clearest difference is in-app purchases: Solid Sales Pro™ at none against PartFive's 2. Solid Sales Pro™ also leads on iOS requirement (12.2 vs 17.0). PartFive's advantage is update cadence (every 3 days vs every 2 months). On price, ads and device support there is nothing between them.
