I wanted to build an app in one night, not tell a single person about it and run some experiments on it to see if I could get it to some level of success. I thought maybe I could get a few thousand downloads and make a couple of hundred bucks.
I wanted an idea that I had no domain advantage in at all, so what better for a chair-bound developer than a fitness app. The 7 Minute Workout was getting a lot of press and buzz at the time on sites like the New York Times and Hacker News, so I already had some customer validation around the idea.
There were a couple of key goals for the app:. Many other ideas and features ran through my head, including:. Given a short time frame all this had to be cut for now. Five hours later I emerged with a couple of screens dynamically filled with different data and some text to speech.
Another hour yep I went over was spent throwing together an icon again a flat colour with the number 7, as my design skills are limited taking some screenshots and writing up a basic description. Built and submitted in 6 hours. The wait begins. After 6 days and a couple of minutes review time it was approved.
By this time there were several other 7 Minute Workout apps in the store. So the aim in the first week was to just let it run without telling anyone and to make no attempt to get press.
I was expecting very little, but was surprised to see that it actually sold a few copies with a steady rank. So version 1. Following the guide for the perfect press release above except I attached 4 promo codes each I sent emails out to ten of the biggest app review sites. Guess what happened? Absolutely nothing, not one reply, one site gave away their 4 promo codes on Twitter, the only 4 promo codes used.
So it appears none of them even installed it with the promo code. So for the next week sales basically ticked along pretty flat. That was 3 hours wasted! What I learned from that confirmed what I already believed — you need to sell your app with a story, preferably to people you have built up a relationship with previously to get noticed. The next stage of the experiment was to expand the market size by adding iPad support. Again keeping it really simple exactly the same views were used within a split view.
So this only took about 2 hours, another 30 minutes to create some screenshots and submit the update. Again it made almost no difference to sales, if anything it went backwards. It was time to go free. Wow did things get interesting! I think the chart says it all. I was floored. It became the 1 fitness iPad app in 68 countries. The 1 fitness iPhone app in 49 countries. And top 10 overall in 12 countries. It even made top 5 overall in countries like Netherlands, here it is on the front page:.
In the US where the majority of downloads came from it made the top 25 overall on iPad. It also lead to some amazing reviews tracked thanks to my service Appbot. One of my work mates came up with a good response. Now I was staring at the stats not knowing what to think. I still have no idea why it has done so well at free. Now came the first part of the blog post, everything that had happened up to this point. And everyone knows the front page of Hacker News is instant success for any product, right?
When the downloads began to fall, they kept falling in a very neat curve. Symantec says 25 malicious apps from over 22 developers were listed on Google Play. Android apps that unethically serve adware and malware are on the rise. A new report from Symantec sheds light on a whole set of new apps that are serving malware and adware to earn revenues in an illegal manner.
These apps, 25 of them in total, have been downloaded almost 2. All of these malicious apps are claimed to have been removed, after Symantec reported them to Google. These 25 apps disguised themselves as photo utility or fashion apps to trigger downloads. They were published under 22 different developer accounts, but shared similar code structure and app content.
Symantec suggests that these apps may have been developed by the same organisational group, or at least using the same source code base. Once you install these malware apps, the app icon is visible on the device, but it soon disappears after a code is executed remotely.
Then full-screen ads start showing up on your phone at sporadic intervals, interrupting the user. Through the app, users can take photos — which are only viewable at 9 am the following day, after taking the time to "develop. The pull of nostalgia, doubled with Dobrik's massive name recognition and influence, has quickly turned David's Disposable into a wildly popular app.
People love David, and this is just another way to interact with him. Dobrik, 23, got his start on the now-defunct app Vine, and now has a YouTube channel with more than 15 million subscribers.
