WindowSeat Wide

Point your phone out a train or bus window and the app stitches thousands of frames into one colossal, perfectly-aligned panorama you can scroll through like Google Maps.

Target user

Travel photographers, train enthusiasts, and tourism creators who want to capture the scale of a landscape, not just snapshots

Features
  • Real-time speed and direction calibration from phone IMU and GPS so the stitched image isn't skewed or duplicated
  • Auto-removes window reflections, smudges, and tunnel dark frames from the final panorama
  • Exports huge JPEG / PNG (gigapixel+) plus a deep-zoom web viewer you can embed in a blog or portfolio
  • Optional 'best frame per segment' picker that grabs the sharpest instant of each stretch of landscape
Why now

The EMF 2026 talk proved the linear-scan technique works, and modern phone sensors plus on-device chips finally have the throughput to do it without specialized hardware.

No mobile app performs linear/slit-scan stitching from a moving vehicle — existing panorama tools (Hugin, Bimostitch, PTGui, Affinity) target stationary multi-shot panoramas, leaving a genuine gap for a phone-native capture-to-pano pipeline.Best Panorama Stitching Software in 2026 (7 Top Picks)Bimostitch Panorama Stitcher - Apps on Google Play

Monetization
3/10

Target audience (travel photographers, train enthusiasts, tourism creators) is small and price-sensitive; the technique is achievable DIY via video + stitching software, limiting premium positioning and recurring use.Can I create a linear side-scrolling panorama from a moving car or train?

Longevity
4/10

Use is tied to infrequent train/bus trips and a novelty effect; once the technique is widely understood it could be absorbed as a feature of incumbents (Instagram, Lightroom Mobile) rather than sustained as a standalone app.Best Photo Stitching Software for Making Panoramas

Feasibility
5/10

Original creator needed an industrial line-scan camera due to throughput limits; phone sensors face vibration, motion blur, GPS/IMU drift, and real-time alignment of thousands of frames — solvable but non-trivial engineering, not trivial.Using the railway network as a flatbed scanner - emfcamp schedule
