For innovators showcasing  at Philly Tech Week's Entrepeneur Expo last night, the demonstration  always required a smart phone,  tablet or laptop.

Launched five months ago, offers a better rewards system for residents  and visitors shopping in center city Philadelphia. Flash the  custom ID code that's been embedded in your smart phone (or dangling from your key chain) and you'll earn credits whenever you make purchases from the 50+  participating merchants. Eventually you build up enough chits to score food and drink and even  yoga sessions. Dozens of indie coffee shops, eateries and service providers (like spas) are already participating in the project, with the heaviest concentration of merchants located between 12th street to the 20s. And yeah, they'd like to go national.

Spawned at last weekend's  72-hour Philly Startup and triumphing over 17 other competitors, Yagglo could prove a refreshingly different browser for the iPad.  In prototype form, the home screen  simultaneously  presents the front pages of six sites, all in readable fashion on your Retina screen. Quite different from the usual bunch of little iPad app icons which then must be individually  opened to see what's up. Yagglo also uses taps and hand swipes to go full screen and then move back and forth quickly between apps.  See a demo here.

Recent Drexel (and Upper Dublin High) grads with a good fashion sense want to help you find and buy the perfect set of jeans. So they've created the about-to-launch - a site where you enter not only your size but also your favorite features from different jeans you own or have tried on. Say you like the way Levi 501s hang on your waist, but prefer the butt clinging of 7 for all Mankind  models, and  the leg tapering of a Lucky jean. Enter your desires and out pops several solutions  that will fill the entire bill, in many cases without totally emptying your wallet, promises CEO Evgeny Pogarelov. How's it all done? With"secret sauce" and a cross referencing data base of 1400 jean measurements.

PalmLing was born of personal travail, said Ryan Frankel, when he was caught in China with a dreaded stomach ailment and couldn't explain the problem to a pharmacist. So he and fellow Wharton-ite Kunal Sarda came up with their travel empowering tool, which lets you call "on any phone, any time of day, from any where in the world" to contact a  live, human translator who will then  talk on your behalf. Say, to  explain  your peanut allergy to a wait person,  steer you onto the right train, maybe even wiggle your way out of a moving violation because you don't know the territory. (Automated apps like Google Translate can't do that for you.)While just a few months old, the  PalmLing service already has a globally scattered crew of 1400 approved translators versed in Spanish, Mandarin Chinese and Hindi (as well as English, of course.) More languages will be added soon, said Sarda. Calls are routed to the translators  who've scored highest in user ratings. $40 buys their services for 10 days, longer and long-term arrangements are also available.

Guys have "no decorating sense," said Cherry Hill dude Joseph Chiaccio at the Entrepeneur Expo. So he's coming to their rescue with It's your one stop shopping headquarters for transforming  a non-descript  basement retreat into the ultimate boy's club - with neon signage, sports memorabilia, the best billiards table, etc.

Want to turn your own pipe dream into a working app, product or service? Maybe you need to get away from it all for a week at the Startup Beach House. While the exact location has yet to be fixed, the development lab will be located on the Jersey shore this summer, in the Sea Isle City/Avalon region, said instigators (and like minded tech developers) David Drager, Mike Bianchini and Greg Berry. Cost of admission is likely to be "about" $350 a person. A TV reality show (or online video documentation) might also spring forth from the project.
