| First of all, the map in TimHiking is a web-based map, you can use it as long as you open the web page without installing APPS. Offline maps are stored as cached files, only temporary files (Internet Temporary Files), not permanently archived to the phone. After downloading, the download location of its route cannot be found. The browser will automatically use and delete cached offline maps according to its own settings. Therefore, it is recommended to download it before hiking and use it immediately.|
Before hiking starts, browse the route you want to follow, then enter the map and click "Download". In this way, you can ensure that the map can be operated normally when there is no network, including dragging, zooming in, zooming out, and viewing photos. However, when there is no network, never close the browser or Reload. Because this is a website, not APPS. If you use it with a good network, no matter if it is an Android or iOS phone, the control is all right.
However, if you want to use it offline, there are some restrictions. First, it is ideal to use an Android phone, such as Samsung, Huawei, mi..., (SONY, vivo are not acceptable). In fact, as long as the mobile phone hardware is not too low-end.
As for the browser, Chrome is recommended for Android, and Safari is recommended for iOS.
Because Huawei cannot download the map normally using Chrome, please use the "Huawei Browser" and select "Access PC Version" to download the map successfully.
Unfortunately, some iPhone users may not be able to use offline maps normally when there is no internet. This is related to the internal design of iPhone Safari and iOS. Internet Temporary Files may be automatically deleted by the system due to lack of memory. Therefore, the map image will disappear after downloading, and the webpage may have to be downloaded again. If there is no network, this problem can be really serious, and it is also a problem that cannot be solved temporarily.
From Apple Discussion Group:
Mobile Safari clears tabs from memory when it receives a low memory warning from the OS. For performance reasons, iOS does not do any paging to disk, so when something is moved out of memory, it's gone unless it's been saved. So the reason you have to reload pages is that other tasks on your iPhone (other apps or new browser tabs) are using memory, so Safari kicks the older tabs out of memory, and when you flip back to them, they need to be re-downloaded.
