OneFlow — Flight Training & Assessment for Aviation Professionals OneFlow brings airline and flight-training paperwork into a single, standardized digital workflow. Instructors, examiners, cabin and cockpit crew, and training managers from any operator — airlines, approved training organizations and corporate flight departments — use OneFlow to plan, conduct, record and analyse training and checking events. Flight safety depends on accurate, consistent training records; OneFlow is built to make them accurate by default. EVALUATE ON THE LINE, IN THE SIMULATOR, ON THE GROUND • Conduct line checks, simulator sessions, recurrent checks and ground courses on your own operator's forms • Competency-based assessment (CBTA/EBT-style competency frameworks) and task-based grading in the same form • Configurable rating scales and pass standards that match your training manual • Per-item comments, oral-question flags and mandatory-item rules keep every assessment complete and auditable BUILT FOR THE COCKPIT AND THE CABIN • Large, stable touch targets designed for use in flight and in turbulence • Rate competencies in sequence without the screen jumping under your finger • Works offline — drafts are saved on the device and submitted when you're back online • Assess several trainees in one session and flag the items that need a briefing note CLOSE THE LOOP WITH TRAINEES • Trainees see their schedule, programmes and results on their own device • Instructor and trainee sign-off with digital signatures on the final form • Licence, medical and qualification expiry alerts so nobody flies on an expired credential TRAINING INTELLIGENCE (MICROSCOPE) • Per-trainee performance history across every form, competency and item • Trend detection, fleet comparison and early-warning signals for at-risk trainees • Training managers see fleet-wide pass rates, weak spots and instructor workload at a glance DESIGNED FOR SAFETY-CRITICAL RECORDS • Every training record is tied to a verified crew identity issued by the operator • Role-based access: trainees, instructors, examiners and administrators each see what they need • Standardized forms published by the operator's training department — one version of the truth across the fleet • Full history retained for audits and regulatory oversight WHO CAN USE ONEFLOW OneFlow is available to any airline, approved training organization, flight school or corporate flight department. Because the app handles regulated flight-crew training records, user accounts are provisioned by your organization's training department rather than by open self-registration — this protects the integrity of safety records and ensures every assessment is linked to a verified pilot or cabin crew member. If your organization isn't using OneFlow yet, visit our website to get started; if it is, sign in with the credentials your training department issued. Fly safer with training records you can trust.

Verdict

The call

The clearest difference is in-app purchases: Lagary OneFlow at none against Peak's 10. Lagary OneFlow also leads on ads (none vs shown) and update cadence (every 5 days vs fortnightly). Peak's advantage is device support (4 vs 2) and iOS requirement (15.0 vs 17.6). On price there is nothing between them.
