How Much Does It Cost to Build a Mobile App?


A mobile app is a great way to bring new ideas to life, add value for your customers, or boost awareness of your business—but only if you can build a quality mobile experience without breaking the bank. And nailing down the cost of an app in advance isn’t exactly easy. App development costs can range from trivial to extreme, depending on a host of factors such as what your app does, how users will interact with it, and how you plan to staff the project.

Unmanned Grocery Stores


Unmanned Grocery Store

These days grocery stores are facing many challenges, like high maintenance costs, price competition with online stores, and limited business hours. All of these issues can be solved with unmanned grocery stores.

Introduction to Mobile Cloud Platforms


If you are building a mobile application of any sophistication, you are likely to need some services to support your app. You’ll need a way to distribute your app for testing prior to submitting to the app store(s), as well as analytics, error logging, crash reporting, and possibly user and data management services. Of course, you could write these services yourself and provision servers to host these services, but why do that when you don’t have to?

Mobile App Development: Native vs Hybrid


Your company needs a mobile app and you want to save money (of course). You want the app live last week, and you’d really like to avoid hiring Android and iOS devs on top of your existing web team.

In light of these considerations, going the hybrid route looks like a pretty good option. Hybrid mobile apps promise to be cheaper and faster to develop, and they’re built with tried and true technologies like Javascript, HTML, and CSS. The hybrid sales pitch can be summarized as “one codebase for multiple platforms”. Hybrid platforms include React Native, PhoneGap, Ionic, Titanium, and others.

Meet Kotlin


Kotlin is a JVM language that hit version 1.0 about a year ago (February 2016).
It is developed by JetBrains, the same people who make my favorite suite of
IDEs. The language itself is open-source under the Apache License 2.0 and is
developed as a community project over at Kotlin is something
that I have become rather excited about over the past year. This post’s goal is
not to teach you Kotlin but to get you excited about it!

What is Pixel Density and Why Should You Care?


Pixel density is the number of pixels per linear physical unit. Measured in pixels per inch (ppi or dpi). Pixel density and resolution are technically the same thing, but often people say “resolution” to mean “pixel count,” a related metric:

count = densityH * width * densityV * height

When other things are held constant:

6 Steps to Improve App Search Rankings


Working as developers, we are focused on the low level technical details of a product, being that a website or an app. This heads down approach often makes us not to pay attention to many high level details that are crucial to bring our product to success. The typical path for a developer, at least at the beginning, is to build an app, put it on the store and then see it fail miserably. If that has happened to your app, then this post is for you!

Introduction to React Native


React Native underlines a JavaScript framework used in writing real and natively rendering mobile applications for Android and iOS. The framework is based on React, which is Facebook’s JavaScript library used in building interfaces for web applications. Building a mobile application using javascript isn’t anything new. The similar technique has been used in frameworks such as Ionic, Sencha Touch, Phone Gap, Cordova, and the list goes on.

Building Android Apps with MVVM and Data Binding


Great Design Pattern for Great Work

Most app development cannot avoid being composed of three parts: database/model, UI and the business logic associated with them.  There are already many design patterns that allow for more structured communications between model and UI; for example, MVP and MVC.

Late Subscribing and Polling APIs with RxAndroid


Howdy, lazy bum! Enjoying the ReactiveX magic? Want to take a look at polling?

I’ll be walking you through a solution I put together for one of our up and coming apps! It works rather well, I learned a lot, and so far no complaints…although there are no users yet either!

Feeling quite charitable, I’m going to let you in on some useful bits and pieces as we build up to polling: threading, late subscribing, replay, manual re-triggering and error handling (a must for preserving replays).
