# Offline maps

> Download a region once and drive with no signal; keep the camera list fresh when you're online.

WhySoSlow is **offline-first**. Once you've downloaded a region, the map, the speed limits, and the
cameras all work with **no mobile signal** — which is exactly when you don't want your driving
display to stall.

## Download a region

On the **Drive** screen (and in **Settings → Map data**) you can download, check, and delete offline
map packs.

<Steps>
  <Step title="Get the Kyiv & oblast pack">
    The main pack covers **Kyiv and the surrounding oblast** — about **112 MB**. Download it once, on
    Wi-Fi, and you're set.
  </Step>

  <Step title="Add other regions">
    Other regions are available as **separate downloadable packs**. Grab the ones you drive in; skip
    the rest.
  </Step>

  <Step title="Manage storage">
    You can delete a pack any time to free space and re-download it later.
  </Step>
</Steps>

<Note>
  The map pack is **not bundled into the app** — you download it on first use — so the app install
  stays small and you only store the regions you actually drive.
</Note>

## Two update speeds

Map data and camera data change at very different rates, so WhySoSlow updates them separately:

* **Map tiles and speed limits** change slowly. Region packs are regenerated occasionally and you
  update them **on demand**.
* **Cameras** change often. The camera list is **small and refreshes automatically** whenever the
  app is online (at most once a day).

Each layer shows a **"data as of"** date so you always know how fresh it is.
