SessionTrail: Photo & GPS Log

SessionTrail — the photographer's session journal. Plan a shoot. Record it on the trail. Reflect on what worked. SessionTrail is a journal-first photography app where the session — not the individual frame — is the atom. PLAN WITH INTENT Title, location, planned window, scoped tags. Auto-geocoded city + country. MapKit picker for precise coordinates. Pre-shoot checklist with reusable templates. Gear kit with snapshot semantics — your loadout survives renames in your gear catalog. Reference images via PHPicker. NOAA-based conditions snapshot for sunrise, sunset, golden / blue / civil / nautical / astronomical twilight, moon phase + rise / set, and Milky Way galactic-core visibility — all on-device, no network needed. SHOOT WITH THE FIELD LOG OPEN Background GPX recording. Photo log per frame with subject, lens, filter, frame number, and stabilization setup (handheld, tripod, monopod, gimbal, slider, drone). Voice memos with titles. Quick reference snaps via the iPhone camera. Pause / resume creates separate segments in the GPX file. REFLECT AND SHIP Editable session times. Map polyline preview of the recorded track. Five reflection prompts (what worked, what didn't, lessons, conditions vs. expectation, free notes). 0–5 star rating. Outcomes — published, printed, submitted, archived, reshoot needed. Share the GPX directly to PhotoMetaPro on Mac.

Background GPX recording survives screen-off through a multi-hour star-trail session. NOAA-based galactic-core visibility tells you when the core is above the horizon during astronomical night.
