Android Things – Electricity Monitoring App

For those who may not know, I live in beautiful sunny South Africa (see my tweets for lots of awesome pictures). A few years ago we battled with a lack of electricity. While “load-shedding” is not so common these days, we have numerous unplanned outages. We even have a few of apps that give out schedules when the electricity is scheduled to go off in your area (see here and here).

How to Stage Rollout Features using Firebase Remote Config (Android & iOS)

The Google Play Store has a great feature called “Staged Rollout“. It allows you to slowly release your app to a percentage of your user base. This feature is not available on the iTunes App Store. Using Firebase Remote Config, we can do much more than just stage rollout an entire app – we can stage rollout individual features within an iOS or Android app. 

By using the Google Play Store staged rollout feature, we can see how well a new version of our app is performing in the field without impacting our entire user base. Continue reading How to Stage Rollout Features using Firebase Remote Config (Android & iOS)

A/B Test your App using Firebase Remote Config

Last week I was in Nairobi and Cape Town giving a talk on Remote Config and Test Lab in Firebase. I had such a great time and thought I should share some of the content I presented online.

What is A/B Testing?

A/B testing is the process of experimentally testing your UI on different audiences in order to determine the best (or most profitable) user experience.  Firebase Remote Config enables us to do A/B testing by allowing us to randomly segment our app audiences easily.
