Poison Maps is an outstanding mapping app, based on the OpenStreetMap database, with over 20 millions points of interest (POI, which is the POI in POIson).
Read the linked article for a walkthrough of the app. The app is a new spin on mapping and works really well.
But what I really love is the new one finger zooming/panning 3D Touch gesture. This is a bit hard to explain, so watch the video embedded below to get a sense of how this works. This so-called “context pan” gesture has uses outside of mapping. The UI folks at Apple should take a look at this.
There’s a free North American version (with an in-app purchase for more POI data), so there’s no reason not to give it a try. There’s also a more weighty (669 Megs) global version, which is the one I have installed on my phone.
