1. Mobile Devices
To run a GPSmyCity app you need any of the following gadgets:
iPhone. Any iPhone that runs iOS 10.0 or later version.
iPad 4G+Wifi Models. Note: cheaper Wifi Only models are NOT good, as they don't have built-in GPS hardware, so the GPS navigation won't work properly.
Android Phones and Tablets. These come in a variety of prices and features. The key thing here is built-in GPS support. Look out for A-GPS, Assisted GPS, GLONASS, GALILEO, BDS, BDS2 or QZSS in device's hardware specification; if it's there, the device is good for GPSmyCity app.
On the other hand, if it says “Wifi only positioning system”, then it means the device does not have built-in GPS functions thus should not be used for GPSmyCity app.
If you are not a techie and don't know how to interpret hardware specification, apply the below rule of thumb to figure out a suitable device based on its price:
2. Optional Devices
External Battery (Power Bank). Using a phone or tablet to navigate a city drains its battery faster than usual. It is therefore recommended to have an external battery at hand, just in case. Otherwise, you may be stressed to have low battery when you need a device to find a way back to your hotel. Fortunately, these days, external batteries are small and inexpensive. We recommend the ones with at least 10,000 mAh capacity.
Charging Plug and Cable. If no external battery is available, make sure to carry a charging plug. In time of need, you may simply stop by any cafe and recharge battery while enjoying a cup of coffee.
