Walk readiness
Great window now
A companion, not a toy
Not a marketplace, not a cute gimmick — a credible outdoor tool that happens to love dogs. Every feature answers a real question from everyday dog life.
Walk readiness
Weather, UV, air quality and pavement heat merge into one score — and a verdict: go now, or wait for the better window.
Live tracking
The route draws in eucalyptus, sniff segments in clay. Mark water, potty, photos and events with one tap — each with a GPS point and time.
Care calendar
Vet visits, vaccinations and treatments with from–to periods, prescriptions and files attached — shared with your family, with gentle reminders.
QR dog meet‑ups
Scan another dog's QR code and plan a walk together. When you're both close, GassiTrail celebrates the meeting and helps you find each other.
Route planner
Plan on the map: start, stops on the way, destination. On the walk, a gentle voice guides you — "left, up ahead", never a drill sergeant.
Route lists & sharing
Save routes to lists like "My favourites", repeat them any day and share them with friends and family.
Groups & pet news
Create local walking groups with a printable group QR — and catch pet news from your city and your country.
Pet Walker mode
Dog walkers scan their clients' dogs; owners watch the walk live — route, markers and all.
Community places
Add parks, water points and pet services to the shared map — with photos and videos. See what other walkers found.
Warm, calm, professional
Eucalyptus and clay on warm stone, type that stays legible, motion that breathes instead of bounces. Risk colors are reserved — never decoration.
