This guide of London is part of a new JSGuide series which, in addition to the classic maps, provides special geolocated tourist maps, with the aim of making easy for you to spot important things.
It offers 21 itineraries, describes 252 sights, and some practical aspects. It's a real tour guide to visit the city by yourself, with a focus on England history. You find many features, as exclusive maps or highlights for practical POIs (see screenshots). Texts are written only for this guide, with an historical perspective. No ads.
The city guide deserves to be used on a tablet (in portrait mode). No native English speakers can easily translate the articles in their language by clicking long on the text to send it in the clipboard, and then use an external online translator.
You can take pictures with the guide and they will be named with the name of the site, visible in the guide, and stored in a folder you can access.
This guide has a lot of functions to discover.
