i have been visiting services api website can't find looking for. question more aimed @ resources utilize rather how should done.

my iphone app requirement able track users nearby, commuting , locate them on map. additional requirement maybe texting them, phone call them, have video session them etc. on high level, convert like

get user details based on longitude , latitude get know if registered users of service subscribed sending message user/users call user using iphone phone api or dedicated app session video call

waze 1 of them. while open source, there quite less documentation on how 1 can utilize backend real time traffic data.

then there geoloqi paid, has ios sdk rich api. cannot find sections useful me when requirements listed above. believe there must many apps relying on such useful service. if of them open source / tutorials, useful resource me feasibility of geoloqi. geoloqi charges users using api, of import me know features come @ cost .

for level of data/information interested in, , functionality, should create own app, dont think need apis.

you can find , send coordinates of people using app server. need determine distance between them, see if in zone of talking, or whatever other functionality have listed above.
