Plotting Weekly Mobile Retention from the Localytics API using R and ggplot2

Part of building mobile web apps is understanding the myriad of mobile analytics and in part visualizing the data to shed light on trends that my otherwise be difficult to see in tabular data or even a colorful cohort table. I’ve been building a dashboard using R, RStudio, Shiny, and Shiny Dashboards aggregating data from MSSQL, Postgres, Google Analytics, and Localytics.

ReactNativeJNI: Check failed: *m_isDestroyed JSCExecutor::destroy() must be called before its destructor

Short post to get this indexed as we didn’t find it elsewhere on the web.

While working to ship a new release of the Find&Save Android app we ran into a crash on launch which only occurred in our release build. The crash was in JSCExecutor.cpp which is part of React Native and left very few hints as to what was wrong with no call stack, Crashlytics logs etc. The only error we had was:

ReactNativeJNI: Check failed: *m_isDestroyed JSCExecutor::destroy() must be called before its destructor

Upgrading an iOS project from Xcode 6 to 7

At work I’m in the midst of upgrading Find&Save to Xcode 7 and in this post I thought I would capture the issues I ran into while migrating our app to the latest build tools. I decided to keep my Xcode 6 install by renaming it “Xcode 6” and installing Xcode 7 along side it and all that worked pretty seamlessly (though keep reading because the AppStore updates will bite you). Once installed I opened our project workspace and hit Project | Build and thus began the journey of our migration.

Platform for Retailers Targeted Local Deals and Notifications

Cash Dash Inbox

Find&Save Cash Dash Inbox

In November ’14 the Wanderful Media team launched a new feature within our Find&Save mobile apps called Cash Dash, a geographically targeted offer platform giving retailers the opportunity to reach consumers at key locations while out shopping. Using location aware features on iOS and Android the platform is able to suggest offers while users are out-and-about shopping. Leveraging our data on hundreds of retailers and hundreds of thousands of retailer locations as well as shopping malls all across the U.S. the platform provides retailers a rich ability to reach consumers at or near their stores with customized messaging and unique offers to help draw them in.

Please make iOS lock screen camera access optional via Settings

My request to Apple on the camera icon on the iOS Lock Screen:

The camera icon on the iOS lock screen is to a child like a Fart Gun from Despicable Me 2 which is to say they can’t stop using it.

Please, make it an option.

If you have young children you can likely relate, if not you should really see the movie it’s quite funny.

But seriously. Can we get an option here?

I’d prefer not to repeatedly have dozens of blurry, pictures of the carpet, couch, floor, ceiling, siblings, goofy faces, all variety of inanimate objects and alas things which shall remain nameless streaming to all my other iDevices let alone getting shared on the big screen via Apple TV.

Seriously, an option. Please.

Wanderful’s Find&Save iOS Applications

My team at Wanderful Media has built two iOS applications for our Find&Save Discovery Shopping experience. Our iPad app is being featured in the AppStore and our iPhone just became available for dowload:

If you don’t want to mess with an app install or are on an Android phone check out our latest Find&Save geo-local Mobile Web implementation.

Now that I have my blog moved I’m looking to post more about how we’re building a discovery shopping experience for over 400 of the nations newspapers which looks a little something like this:
