Onoff - Interview with the developer of a fantastic app

Did you have any prior development or coding experience?

Yes. Before I joined the Onoff team, I worked for more than 4 years on mobile, automotive, and embedded projects, mainly Android, but also was a lot of Javascript, AngularJS, and HTML5, web and mobile versions.

What was the most challenging aspect of developing mobile app?

The most challenging was to implement a third-party VoIP library, especially if it has a lack of documentation and examples. After that creation, own calling interface, which can handle incoming, outgoing calls, multiply calls, and so on.

The interview was answered by one of Onoff's engineers based in Estonia. Onoff Telecom is a licensed telecommunications operator in 21 countries and supplies numbers from 33 different countries.

Name a few of your favorite apps and reason you love them.

I like the Telegram application. It is functional, simple, and secure, without bloatware inside. Maximum-focused application.

How long have you been working on this app?

Quite a lot of 7 years. (6 years and 11 months.)

What need of the user did you have in mind when developing this app?

I believe that the application should be simple and understandable, so users can easily use our application. Of course, stability and performance are important too, but it is matter-of-course, we always trying to achieve the best result, despite the huge number of different devices and complexities.

In what way do you think your app is better than similar apps on the market? Please describe in detail what innovation you think you bring and what you are proud of in your app.

I think it is 3 main points, which make us better: First of all, you can get a real mobile number, with SMS and even MMS (Not yet all countries support it, but we are working on it). Second is our callback system, which allows users to spend less on international calls. And third, is easy to get a number, you can get a number in a minute and start using it.

What are your future plans and expected features of the coming new versions of this app?

We are working now on a feature, which allows the user to use his number offline when the user has no internet and only a GSM network available. Quite a big and complex feature, but we will do our best to bring it to the user.

Assuming new users of your app are reading this page. What do you want to ask them to do (contact you about X, Share the app, etc.)?

Please don't hesitate in sending us feedback! How are you using our application? What kind of functionality you are missing? What do you like? What not? It is very important for us to make our application better, and to understand what you need, so that we could make you happy.
