Not perfect but better than Google maps
Ive used Google maps for urban walking and it was extremely frustrating. Navmii, on my first test, was far better in recalculating the route if I didnt follow the route Navmii suggested. But, it sucked the hell out of my battery. On average, it took down my iPhone 5 battery at 1% of charge for every 1 minute of navigation. I havent upgraded to the ad free version yet so some of that battery use may have been all the crap being pushed out to my phone. The phone also got very warm when navigating. At walking speed, there shouldnt have been a lot of calculating going on in the app.
Id also really like them to optionally remove the music player controls. This is a nav app, not a music app and the music control takes up a disproportionaltely large amount of screen space. Its not like the built in iphone music control is that far away.
Finally, in the Location Services menu, Navmii can be set either to "never" or "always" but not "while using" like most other apps that need this service.
All things considered, I may buy it anyways to get rid of the ads, because its so cheap. But, I may spend the big bucks and buy the Garmin app for an upcoming London, UK trip (all walking) because I use Garmin on my motorcycle and car and they are far better.
