SpotterLog vs PlaneSpotter Guide
A guide tells you what to look for. SpotterLog keeps everything you've found.
Reference apps are great for learning to tell a 737 from an A320. SpotterLog picks up where a guide leaves off: the moment you photograph an aircraft, it's identified, dated, located, and saved to a collection that grows with you — backed by a database of over 400,000 aircraft.

What PlaneSpotter Guide does
PlaneSpotter Guide is a learning app: quizzes and profiles for around 100 well-known aircraft types, a few free and the rest behind a one-time purchase. It's a fine way to study, but it stops there. It can't tell you which specific aircraft you just photographed, where you were standing when you saw it, or what's happened to that tail number since. SpotterLog does all of that — it identifies the exact aircraft from your photo, geolocates the sighting, and saves it to a permanent collection drawn from over 400,000 registered aircraft, then watches each one for ownership changes and the complete NTSB accident history. A guide teaches you the types; SpotterLog keeps the record.

Why spotters choose SpotterLog
Where a guide stops at a fixed set of aircraft, SpotterLog keeps growing with you. We hold over 400,000 registered aircraft in our database, the complete NTSB accident investigation history, and we actively store the last-known location of more than 150,000 flights every day. Photograph an aircraft and SpotterLog logs it automatically — geolocated to exactly where you were standing when you took the shot — so you can revisit your sightings years later. Get alerted the moment a plane you've spotted is involved in an accident or changes owners. SpotterLog works fully offline and syncs when you're back online, and every feature is available on both the iOS app and the web — a mobile-friendly site that works great on Android and tablets too.
