WhySoSlow is a personal project — free, no subscriptions. It covers Kyiv and the surrounding
oblast today, with other regions available as downloadable map packs.
Quickstart
Install, sign in, download the map, and take your first drive.
The Drive screen
The heads-up display: your speed, the limit in force, and colour-coded alerts.
Speed cameras
How the ~30-second, direction-aware camera warnings work.
Offline maps
Download a region once and drive with no signal; keep cameras fresh.
Your limits & markers
Fix a wrong limit and drop your own markers — even in motion.
AI sign advisor
Optional: let the camera read roadside signs and suggest limit fixes.
Account & privacy
One free account, what’s stored, and the permissions it needs.
FAQ
Coverage, platforms, battery, and the honest edges.
The idea in one minute
1
Mount your phone and start a drive
Put the phone in a car mount with the screen on, open WhySoSlow, and tap Start. The map
follows you — there’s nothing to type and nothing to tap while moving.
2
Watch one honest number
Your speed sits next to the limit in force. It turns amber the moment you’re over the posted
limit and red once you cross Ukraine’s +20 km/h fineable line — a single calm beep, not
a siren.
3
Let the cameras warn you first
About 30 seconds before each automatic camera you get a distinct alert — only in the
direction it enforces, and at the camera’s own limit.
4
Fix what's wrong
Spotted a bad limit or a missing camera? Correct it from the driver’s seat. Your edits sync
across your phones and survive map updates.
