Use Trails to track your lost iPhone

Trails is the first GPS app that allows you to record, export AND IMPORT directly on your iPhone!

Record your hikes, bike trips or jogs directly on your iPhone gps tracker. Easily import tracks by simply searching on popular GPS websites such as everyTrail.commapmyrun.com and bikely.com to find hikes and jogs of other users and follow their tracks on your iPhone.

Right now the iPhone updates my location only when I go to an app that requests it. On my iPhone these include Google Maps, Loopt, Whrrl. WikiMe, and Earthscape (to name a few). For many of these apps this setup works fine; they are geobrowsers. Once the app has my location it lets me know what relevant information they can provide or how to get somewhere. Loopt and Whrrl, though they are part geobrowser, have a very different set of functionality. They want to let me know where my friends are. Right now they can't. They can only tell me where my friends were the last time they logged in and location is information that degrades quickly.

Apple does not allow third-party apps to run background processes. If they did an app could have a "iphone gps tracking" running in the background and it would update that app's (and probably only that app's) servers every 15 minutes (or so). The app would also be able to alert me when I wandered near a friend or if there was a Wikipedia article about a nearby statue. This would, of course, kill my battery and slow the system down (especially if I had multiple apps that wanted my location).

Instead of allowing third-party apps to run background processes Apple has promised to provide them the ability to push messages to the client. This is perfect for apps like instant messaging; it can alert me when a friend has pinged me. Or a calendar that can remind me when I have an appointment. However this system will not work for location-dependant apps. How can Loopt or Whrrl accurately let me know that a friend is nearby when it doesn't know where I am? It only knows where I was. Apple has to check my location periodically and make that information available to trusted apps.

Why do I want this functionality? I'd like to get metrics on my daily path (How long do I spend grocery shopping vs. the gym vs. home?). I'd like to let friends know when I am near (and vice-versa). I'd like to be alerted when I am near a virtual note. In theory I'd like to at least have the option of being alerted with a location-based coupon. I want to learn about what I do, not what I think I do.

You can export your tracks with two clicks in the standard GPX Format. This allows you to geotag and geocode your non-iPhone photos (via e.g. HoudahGeo) or to share your track with others via Google Earth, etc. Or upload your tracks directly to everyTrail.com or into your TrailRunner log with a single tap!

2012 Eastern Battery Freestyle BMX Bike $279.99 2012 Eastern Battery Freestyle BMX Bike.

Because first-time riders can actually be harder on their equipment than expert riders, the Battery uses heavier steel tubing than pro BMX bikes. Components are heavier and more rugged, too. Rugged, fun, well-made and affordable, the Eastern Battery is the perfect bike for young riders who want to take a stab at perfecting jumps and tricks or who want to cruise the neighborhood in style.
