Find friends easily with Space-time app
Unlike most locator apps, this one doesn't drain your battery or require friends to install or sign up for anything. Genius!
There are any number of apps that can help you pinpoint a friend's location, but they all have one thing in common: they require that friend to have the same app installed and running, and usually to sign up with YAS (Yet Another Service).
And don't forget, it's a two-way street: you have to run the app yourself, and leave it running all the time -- a pretty big drain on the ol' smartphone battery.
Enter Space-time for iOS, a clever cross-platform locator app that runs only when you need it to and requires no installation or setup from anyone else.
It works like this: you tap Request Someone's Location, then choose a contact from your address book. The app creates a text message to that person, one that includes a brief explanation ("Where are you? Click here so I can see") and a link. If you want, you can tweak the message before sending it.
When the recipient gets the text, all he or she has to do is tap that link and approve a one-time location-services request. Then the person's location is delivered back to you within the Space-time app, where a tap brings it up on a map. It's that simple.
Because this is entirely SMS-based (for the recipient, anyway), there's nothing to be installed, configured, or registered. Plus, the text message should work with any GPS-enabled smartphone, not just iOS-based ones. I tested Space-time with another iPhone and a basic Android phone, and it worked perfectly with both.
I can recall a number of times when I needed to find someone, but couldn't because they weren't linked up with me in Find My Friends, had a non-iOS phone, or didn't want to install a new app. Space-time solves that problem with ease -- and for free. I'm an instant fan.
