SessionTrail: Photo & GPS Log
Photo session journal & GPX
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Plan the shoot, record the journey, review the results. GPX tracks, voice memos and photo logs — now crash-proof, transcribed on-device, live on your Lock Screen.
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.
SESSIONTRAIL PRO — ONE-TIME UNLOCK
For working photographers who need the next layer of detail. Pay once, owns the app forever, no subscription:
- Multi-day sessions with the per-day chip filter on the Shoot tab
- Trips — group "Iceland 2026" or "Provence Lavender Week" under one window, one currency, with aggregated costs
- Per-session and per-trip cost tracking with live variance, 50+ curated currencies plus any ISO 4217 code
- PDF reports — one-page session report and multi-page trip report with title, dates, location, plan, conditions, gear, reflection, rating, outcomes, costs, photo log and GPX stats — ready to file, print, or attach to a competition entry
- Multiple GPX tracks per session — stop / start during a session and morning hike + evening walk become two separate, shareable .gpx files
- Sparse + Dense GPS modes — Sparse (5–30 min, GPS duty-cycled for multi-hour landscape and astro shoots) and Dense (1–10 s sampling for wildlife and events). Standard (15–60 s) stays free.
- GearGrove kit sync — apply gear loadouts managed in GearGrove with one tap
- Recap PNG exports for sharing a polished session or trip card
BUILT FOR NIGHT PHOTOGRAPHERS
Astro appearance mode (red on black) preserves your dark adaptation under the Milky Way. 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.
PRIVACY BY DESIGN
Metadata syncs via your private iCloud database. Heavy artifacts — GPX file, voice memos, reference snaps, PDF reports — stay on the recording device. Nothing leaves your phone except through the standard Share sheet you control.
Full localization for English and German. Made with care in Switzerland.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Your shoot data is now safer than ever — plus two features you can see.
Live Activity: an active GPX recording now shows on the Lock Screen and in the Dynamic Island — elapsed time, logged points, and pause state at a glance.
Voice memo transcription: transcribe memos right on your device. Audio never leaves your iPhone.
Crash-proof GPX recording: if the app is ever interrupted mid-shoot — dead battery, force quit — your track is recovered automatically at next launch.
Voice memos now survive interruptions like phone calls and continue recording.
Deleting a session now also removes its files from your device, as expected.
New in Settings: Storage — see how much space your sessions use and clean up leftover files from earlier versions.
Large bundle exports no longer freeze the app.
Clearer feedback when a recording captured no GPS fix.
