An Insider’s View of Mobile-First Design: Don’t Make These Mistakes

I hope designers, product managers, and entrepreneurs can learn something from them — not just about how to design for mobile, but about how to think differently about mobile design. But these opportunities are also design constraints: Mobile screens are small, driven by touch, and often connected to spotty networks. Instagram’s technique here helped us with an early mistake we made on our mobile app, Polar, which allows people to collect, share, and vote on opinion polls. Contrast this standard approach to the one employed by Instagram’s mobile app: When people like or comment on a photo on Instagram, the results of their actions show up right away. Treating desired actions (in our case, voting on polls) as part of the main activity of our app — instead of as separate interface elements — makes a huge difference in their use.

Polar Users Have a Favorite Yahoo Logo. Will Marissa Mayer Agree?

And judging from Polar users’ preferences, the plain and modern approach is smartest right now. Wroblewski says he created the logo polls on Polar because “this thing is near and dear to my heart. The version from Day 10 is the only one with a clear mandate: Polar users prefer it to the original by a margin of 69 percent to 31 percent. But if she were listening to users of Polar, a new social polling app for smartphones, there would already be a clear winner. The Polar app, available only for iPhones so far, shows a scrolling list of survey questions contributed by users, each with just two possible answers, illustrated with big pictures.

Social Voting App Polar Has Had Over A Half Million Votes In Its First Eleven Days

For Polar, Wroblewski wanted to make everything insanely fast:We knew we were making it fast and easy, in the past eleven days we’ve had a half a million votes. Vote, Vote, VoteTaking fast action is fun, that’s why a lot of people use Facebook’s Poke feature. Watch this video:Not only is the app fast, but the ability to get people to vote for things is quick too. Today, I spoke with one of the co-founders of a company called Input factory, Inc., that’s behind a new social voting app for iOS called Polar. How obsessed was the team with making Polar fast?

Bagcheck Founder Launches Polar, A Micro-Survey Mobile App

Learn morePut it in another way: As Quora is to blogging, so too is Polar akin to microblogging. The goal is to get people to share their opinions and offer feedback to people’s questions in a fun, engaging way. It tells us that the average votes per user is in the hundreds with more than 20 votes per user visiting the app. Well one service is hoping to solve this problem and it’s having a bit of fun with it too. Why can’t there be a way to poll and solicit someone’s opinion about something without having it be so mundane?

Daniel Raffel's Favorite New Geek Stuff Of 2010

The iPad app, which launched this year, is particularly powerful given the flexibility of the additional real estate. The post below is an updated list of his favorite new geek stuff from 2010. Uber’s goals appear to stretch beyond the creature comforts of simplifying a pickup via a mobile app and offering a high quality ride. The Android app is a faithful reproduction that feels more buggy than it should. Integrating voice recognition into mobile services is a trend that’s likely to accelerate next year and the good news is that it’s never been easier.
