I need an application for IOS and Android with the following criteria:
Please bid only if you can make such an app and you have experice in this area.
- Measure distance between 2 cell phones
- Long range with GPS
- Short range (under cca. 30m) with signal betwen the 2 phone. (singnal time can be measured to calculate distance, but any other way can be ok)
- It must be cm accurate in short range
- In short range, distance can be enough, if it can specify direction it is a big plus
