A small work sample

2. What’s in here?
Just to show a piece of the work we’ve done here:
 What’s the SweatDrops app?
 How it was conceived?
 Two functionalities samples:
 People’s nearby
 Loading fitness/sports events

3. SweatDrops
 What’s that?
A social network targeted to sportists, athletes and fitness
lovers. For example you can (not limited):
- Find people with you same interests (i.e. someone who may
want to jog with you) and follow them.
- Find events near you (i.e. a Triathlon contest in Miami) and
participate (check in) on those events

5. App’s function example:
People’s nearby
Want to find somebody around me to run 10 miles in San Francisco?
From the device’s GPS: Lat/Long
Call a secure restful RoR service:
Json result with
people located
near me

6. A small code sample fragment
Technical
The Ruby controller for the people’s nearby web service
Get coordinates from the phone’s GPS
Passed by parameters for this case
Use the geo_scope gem to search by lat/long
Refine query (backwards
compatibility)
Render json string

7. Other App’s functions
My profile
My name and my network
Sport events I’ve
attended/participated
There’s a RoR restful webservice
for all of these functions.

8. The heart of the system: The
events
 The system is conceived around the events.
 Event examples:
 Marin Count Half Marathon, 10K and 5K
 Zumba class by Mihaela Stanciu at San Francisco
 Let’s job for fun in Lake Merced 3 miles
 Why?
 In this world, you build your network over sports/fitness
events.

9. How Sweat catches events?
 From the users:
 From third parties via their APIs
Active.com Zumba
MindbodyOnline.com

10. Catching events from third
parties
 Zumba, active.com and MindBody offer APIs to grab
events from their database
 Using Rails rake:tasks:
 Invoke the webservice
 Insert the events in the database
 Keep track
 Live code for a similar problem:
