Blaze carries the maps other people made.
The paddling and backcountry maps you bought, and the free topographic sheets
governments publish — imported once, drawn on your phone, and readable with no
signal at all.
BRING YOUR OWN MAPS
• Esri tile packages (.tpkx) and MBTiles are read exactly as they came. No
conversion, no re-compression, no waiting: a 1.5 GB map is ready as soon as it
has finished copying.
• Garmin and Google Earth overlays (.kmz) are redrawn into tiles once, when you
import them.
• Import from Files, from a share sheet, from AirDrop, or by pasting a direct
link to a map file.
FREE MAPS, ALREADY CONVERTED
A built-in directory of government topographic sheets you can download inside
the app — Canadian CanTopo and CanMatrix from Natural Resources Canada, and
historical quadrangles from the United States Geological Survey. Every entry
shows its licence and its download size before you tap, and a map installed
from the directory keeps its attribution beside it, always visible.
Where a map is not free, Blaze tells you where to buy it. It never serves a
publisher's bytes on their behalf.
BUILT FOR NO SIGNAL
Imported maps are offline by construction. A coarse basemap of the whole of
Canada can be downloaded before you leave, so there is ground under your maps
even where nothing has been published.
Stack several sheets, set how strongly each one draws, and jump straight to a
map that is hundreds of kilometres away rather than hunting for it by panning.
Rename any map that arrived carrying a filename instead of a place.
RECORD WHERE YOU WENT
Start a track and it keeps running with the phone in your pocket. Mark a spot —
a take-out, a campsite, a fallen tree — and export the whole trip as a GPX file
to whatever you use at home.
Battery saver stops drawing the base map entirely. Under a full-screen imported
map there is nothing to see underneath it anyway, and not drawing it is work the
phone does not do.
NOTHING LEAVES YOUR PHONE
No account. No sign-in. No sync. Your tracks and waypoints are written to your
device and stay there; they leave only when you export a file yourself. Blaze
has no way to send them anywhere, and that is a property of the code rather than
a promise about our intentions.
Maps are fetched from a static file host. Nothing about where you are, where you
have been, or what you have marked is ever sent with the request.
WHAT IT IS NOT
Not a trail directory. No reviews, no ratings, no photos, no feed, no
leaderboards. Blaze carries maps and records where you went, and it is finished
at that.
