Log Viewer for ArduPilot
Flight Replay & Data Analysis
Free · In‑App Purchases
Replay your ArduPilot flight, compare recorded signals and inspect findings with context. Open a DataFlash .bin log on iPhone or iPad to get started.
Turn ArduPilot flight logs into a clear picture of your flight. Log Viewer for ArduPilot opens DataFlash .bin files on iPhone and iPad so you can replay the route, compare signals and inspect the recorded configuration.
FOLLOW THE FLIGHT
Explore the route on a map with flight modes, events and a time cursor. Scrub the timeline or replay at 0.5–8× speed. Keep the map, charts and messages aligned to the same moment.
COMPARE YOUR SIGNALS
Plot multiple numeric fields together, zoom into a time range and compare recorded values. Choose individual fields or available presets for vibration, GPS versus barometer altitude and ESC current. See altitude, speed, satellite count and current along the timeline when the log contains the required data.
INSPECT FINDINGS IN CONTEXT
Run checks on supported recorded data, including events, vibration and GNSS. Review findings, data coverage and available evidence. Missing or unsupported data stays explicitly unknown; the app does not assign an overall flight health score.
UNDERSTAND THE CONFIGURATION
Search read-only parameters and compare the last recorded values with defaults stored in the log. Filter differences and see where a default is unavailable.
EXPORT WHAT YOU NEED
Export selected signals to CSV with timestamps, or share a chart as a PNG image for further analysis and discussion.
KEEP YOUR WORKFLOW CLOSE
Import through Files, iCloud Drive or compatible file providers. Reopen logs from your recent-flight library. Use English or Ukrainian, switch between light and dark appearance, and explore the built-in demo flight before importing your own file.
Log processing happens on your device. Map imagery requires an internet connection. Available signals and checks depend on the data recorded in each log. The app reads existing DataFlash .bin logs; it does not connect to an autopilot or change its parameters.
FREE DEMO AND PRO
Explore the included demo for free without starting a trial. Importing and analyzing your own logs and exporting CSV/PNG require Pro or an active trial. Pro Monthly and Pro Annual are auto-renewable subscriptions with a 7-day free introductory trial for eligible users. Pro Lifetime is a separate one-time purchase. An optional 7-day Trial provides Pro without automatic charges; it does not buy Lifetime. Imported files remain on your device when access expires. Prices and billing periods are shown in the app before purchase. Restore purchases in Settings.
Subscriptions renew automatically unless canceled in Apple account settings. Lifetime does not cancel an existing subscription.
