When developing mobile apps and web sites, we often use observables to populate the UI of our app with external data, asynchronously. In this article, we’re going to learn about the concept of the Observable: what they are, why we prefer them to other methods of handling data, how RxJS works within this context, and […]
When I have gone to talk at conferences and demoed my well-travelled PocketRave app, I get a lot of great questions about NativeScript, Angular 2, and the Angular Advanced Seed code that were used to build the mobile app. We have a cool dance party at these talks as people download the PocketRave app and […]
So, you need to build a web site. Great! If you’re an Angular developer, you immediately dash to your favorite IDE and start scaffolding out your site. But wait! Maybe you also need to build a mobile app to accompany your beautiful new site. Now what? It’s become clear that Angular 2 is not just […]
Here at Progress we’re infatuated with Pokémon Go, the Pokémon collecting app that has taken the world by storm. As such, we’ve invited a few of our Telerik Developer Experts to talk about the game, and the longterm impact it’ll have on the mobile and business worlds. The questions for today’s Slack chat are: What […]
Every mobile developer’s professional life is dominated by those little moments where fingers hover over the keyboard while the developer waits patiently for a window to appear on the screen containing a version of the mobile app over which he or she has been laboring. Over the course of a day, these individual, hopeful pauses […]
Whether we realize it or not, we have been interacting with bots, especially voice bots, for some time now. The somewhat annoying voice-prompter of some airline support lines (the ones that have enough voice-recognition ability to hear me yelling “Customer Service!”) are powered by types of bots. Cookie Monster taught us how to use “Hey […]
I’ve been intrigued by beacon technology since I received my first developer kit of Estimote beacons in the mail. Beacons contain so much potential in such a small package! Recently, beacons, and platforms to host them, have started proliferating in the Maker movement and have started to appear in retail stores such as Alex and […]
In my talk from this year’s Fluent conference I discuss Eddystone beacons, the physical web, cultural installations, treasure boxes with treasures, and Kendo UI-powered web sites.
I have been a big, big fan of Parse. It was one of the best backend-as-a-service providers that was particularly developer-friendly. I started using it several years ago as an indie mobile developer, creating mobile apps for families, kids, and to promote fitness with all kinds of bells and whistles like awards, push notifications, data […]
Last April, I introduced the concept of the M.I.K.E. web stack, which was hatched from a few too many cocktails at a company party with my co-workers. I wrote an article about it and introduced it at our company’s conference, TelerikNEXT. M.I.K.E. stands for a web stack built using MongoDB for the database, io.js for […]
Many developers jumped onto the hybrid mobile train as the Cordova ecosystem became more and more mature. It seemed, and to many still seems, like such a win! You can use your current skills as a web developer to build what is essentially a small web site that runs in a WebView on a native […]
Every hybrid mobile app developer has that moment. You know the one I’m talking about, when someone asks you, “So what kind of mobile apps do you develop?” Depending on context, a follow-up question might be, “Well, are you developing these apps natively?” meaning, using native languages like Swift, Objective-C, and Java. Bravely, you might […]
I admit that I have had the familiar AdBlock extension (“Chrome’s most popular extension!”) enabled on my web browser for a long time now. It was actually shown to me originally by my daughter, who found ads disruptive to her internet usage. For kids, the option to not see ads is one of the main […]
Building mobile apps is hard, but Telerik AppBuilder takes a lot of the pain out of the creation and launch process. In this talk, I walk through bringing your mobile app project from a twinkle in your eye all the way to the app stores, all within the AppBuilder environment. Starting from a paper prototype, […]
If you have any retail-oriented apps installed on your phone, you may have had the experience of being bombarded by notifications when you are at a shopping mall. For instance, every time I so much as drive by our local mall, the RetailMeNot app makes my phone go bananas – popping notifications all over the […]
It’s a familiar story by this time. The solo developer works for a year on a beautiful game or app, releases it to the app stores and…nothing. Downloads are elusive, reviews are spotty or nonexistent, the app is buried in a sea of Flappy Bird clones, Candy Crush spinoffs, and Korean sticker-sharing chat apps. For […]
CatchMe – July Featured App. Find your friends’ locations using Facebook and Mapbox The CatchMe App was built using Kendo UI Mobile on Telerik’s AppBuilder platform using the Visual Studio plugin for AppBuilder.

Wouldn’t it be cool if we could create a device that uses a microprocessor (maybe by analyzing our brain waves) that could predict trends in the future? Progress, the parent company of Telerik, commissioned a report based on interviews conducted with 675 application developers regarding their experience with the Internet of Things. The report tries […]
BRS App – Supporting the Basel, Rotterdam and Stockholm Convention Meetings on Chemical and Waste Management The BRS App, built using Kendo UI Mobile on Telerik’s AppBuilder platform, provides a window to information about the meetings of the global chemicals and wastes conventions.

The arrival of the Apple Watch has sent some developers scrambling to update Xcode and either create a new, watch-friendly app for distribution in this new ecosystem, or add a watch app as an extension to an existing iOS app to enhance a previously-developed project. In our case, we wanted to use the arrival of […]

It’s Spring! The flowers are blooming, the garden is defrosting, the birds are singing, and it’s almost time for Easter, Passover, or other Spring holidays that celebrate rebirth and renewal. Even in snowy Boston, where I live, the snowdrifts are slowly disappearing. What better time to organize an Easter egg hunt or Spring scavenger hunt […]

Call 911! Your app icon is a train wreck. People look at it and shudder, or worse, they don’t look at it at all. Many developers don’t think about their mobile app icon until they’re ready to deploy their app onto their device for testing, or even when they’re almost ready to send their app […]

In an ideal world, every mobile app developer would be able to build an app and test its behavior on a simulator that would perfectly mimic the way the software should behave on a mobile device. To a large extent, products such as Telerik’s AppBuilder have perfected the mobile device simulator, giving the developer a […]
In the first part of this article, we learned how to scaffold a basic Ionic app and connect it to the Telerik Backend services to allow users to register, login, and access content.

Building apps using hybrid mobile technologies has enabled developers to deploy beautiful products in record time. Recently I completed an entire app from sketch to launch in one week in order to catch holiday shoppers. Scaffolding a great UI using nice frontend development tools makes things easy from a visual perspective, but the real meat […]
The idea of creating consumer-ready indoor proximity systems has been the dream of many startups recently. While satellite-driven GPS works brilliantly for positioning your car on a road, it doesn’t work so well for more fine-grained positioning. You might want to find a spot on a given floor of a building, a brand of soup […]
One of the toughest challenges in building mobile apps is how to monetize them – in other words, how to make money from all your hard work. Some apps have a built-in monetization strategy, in that they are bundled with a larger web product and exist to enhance the desktop experience. Releasing your app as […]
The App store now allows app videos along with screenshots. Google Play has had them for a long time, but now your iOS app can have one, too. For many developers, this is exciting news! This means that you can now submit up to 25 screenshots (5 screenshots per screen size) and an app preview […]
