Hang out with us and enjoy complimentary food and drinks. This is a great opportunity to meet our partners, developers and customers. We’ll have developers and friends on hand to answer your any questions you might have about current and upcoming products!

Space is extremely limited (and almost full), so RSVP now to ensure your spot.

Apps built at the Tropo + Geoloqi Open Gov Hackathon

Thanks to everyone who came out to the Open Gov Hackathon today! We’re proud to announce the winners! The best app using the Tropo API went home with a Sonos Wireless Music System, and the best app using the Geoloqi API went home with an iPad!

The judging began at 6:30Pm, and everyone stopped programming. After all of the presentations were done, we discussed each app with the Tropo team and Rick Nixon of CivicApps. It was a tough decision, as the entries were extremely creative and useful!

Thanks to everyone who watched, participated, and cheered on the developers. We owe the greatest thanks to Tropo and the City of Portland, who were great supporters of the event. This won’t be the last hackathon. We will be doing this again in the future as soon as possible. If you’re interested in partnering with us for another hackathon, let us know!

Heritage Tree Quest

Winner: Best use of Tropo by @trisimon

Like PacMan for heritage trees! You go around town finding trees and collecting points. You get bonus points for collecting all trees in a neighborhood. You receive your score via an SMS from Tropo. When you’re near a tree, you can call Tropo and it will quiz you to identify it, getting you even more points! It was this clever use of the voice recognition capabilities of Tropo that made this application stand out.

Don’t Eat That!

Winner: Best use of Geoloqi by @reidab

“Don’t Eat That!” pulls health inspections from the county web page. If you use Geoloqi, you can subscribe to notifications of scores under a certain threshold for restaurants within 100 meters of your current location. You’ll get an SMS that says “What ho! You might not want to eat at Backspace, their last inspection score was 93!” That way you can gawk at dirty restaurants near you! This app will also post links to the reports as tips on Foursquare!


Honorable Mention. Finds all the bars in the business license dataset and matches them to Twitter feeds by searching Twitter lists. The map shows notification icons on the map and shows the latest tweets from every bar. A future mobile version could use the Geoloqi API to track your location and receive Geonotes for specials at bars near you.

Honorable Mention. Finds pets available for adoption from the Multnomah County Animal Services database and You can read the descriptions of the animals and send out a tweet for them. Using the Tropo API, the non-technical foster homes can call in and ask for a short update about the pet, so the shelters aren’t required to know how to use Twitter. On “Woof Wednesday” the dogs that are looking for homes will tweet their latest updates or a random pet.

We are thrilled that everyone was excited to come out and join us for a day of hacking! And special thanks to Tropo for co-sponsoring the event and to CivicApps for the great support.

Tropo is Easy!

Chris Mattieu writes: “Reflecting on the event, I wanted to share an interesting observation that I had during the course of the contest. The winners of the iPad, Amber Case and Aaron Parecki, were not originally in the contest. They were hanging out with us at the event working on their totally awesome side project called GeoLoqi. Halfway through the event, Aaron looks in my direction and says that he is interested in integrating Tropo SMS with GeoLoqi. Several minutes later his iPhone buzzes with an SMS and he looks at me and Amber and says, “It worked! GeoLoqi just me an SMS notification triggered by my location!” This was certainly very exciting for all of us but it the event gets more interesting…

Amber and Aaron left to get some sleep and came back in the morning for breakfast with an idea to enter the contest. Their idea was ChatterCast, a mashup of Tropo, Socrata’s, Instamapper, and GeoLoqi services. Basically ChatterCast subscribes your phone to real-time 911 call data provided by ChatterCast alerts you based on your location of 911 events happening around you.

This is a great example of how someone with an idea can not only win a contest only after getting started in the final hours but how anyone with an idea can change the world. Tropo’s ease of use makes it super easy to communicate with telephones via voice and SMS or even IM and Twitter with a couple of lines a code. There’s no reason not to add telephone support to your existing web applications to make them even more powerful in this mobile and social age we live in today.”

Geoloqi-Powered ChatterCast Wins Seattle Open Government Hackathon!

This weekend we participated in the Gnomedex10 Open Government 24 hour Hackathon. Tropo sponsored a lounge at the Edgewater hotel with food, coffee, wifi and couches for open data geeks to build apps in. Participants were encouraged to make the best app using the Tropo API and (powered by Socrata).

We quickly realized that we could use the Geoloqi API to build a local emergency alerter app that could run on almost any platform. In the span of around 5 hours (plus about 4 hours getting the Geoloqi API ready), we built ChatterCast, a app allowing one to subscribe to XML feeds based on one’s location. We used the Geonote methods of the Geoloqi API to handle delivering the location-specific messages. Geoloqi used Tropo to deliver SMS messages to the phone.

We finished with just enough time to present before we had to catch our train back to Portland. We had to leave before we were able to see many of the other presenters. We caught about half of a great presentation by Portland geohackers and open gov enthusiasts Reid Beels and Max Ogden. Their app notified users the day before events happened in user-specified ‘watch zones’, e.g. road closures on your commute. They won for best use of Tropo, another success for Portland’s open government community!

Note that the app is simply a proof of concept. While it fully works, it requires installing Instamapper on your mobile phone. Instamapper runs on most mobile phones, including some older Motorola models such as the Boost Mobile phone. This means that even some users with older phones can still have access to this data with ChatterCast. If you’re unfamiliar with Instamapper, we wrote a post on it here.

Here’s an example Geonote SMS message from the 911 call dataset.

We had a great time building this app! Now we have a framework for digital storytelling and geolocal data. Anyone can use Tropo, Instamapper and the Geoloqi API to build their own app capable of pushing XML data to a user by SMS. We’ll be integrating ChatterCast into the Geoloqi API so that the mashup can be more accessible to developers and end users.

Thanks again to Tropo, Socrata,, Gnomedex and all of the great open data hackers at the #tinkerstorm hackathon event!
