The Magic Formula For Getting Your App Featured By Apple


It’s the dream of pretty much everyone who has worked on an app to get an app featured by Apple.  By now I’m sure we’ve all heard the stories of ridiculous profits that can be earned within a few days.

Now the problem is, how does Apple choose which apps are featured?  I’ve seen absolute junk get featured in the Canadian app store while some brilliant apps seem to get glanced over.  So unfortunately,  no matter what luck definitely seems to be the biggest factor in the formula for getting your apps featured in the magic formula.

All that being said I read an interesting article from one developer who was able to get their app featured by Apple, a game known as Alienz which was able to reach the top 100 strategy and arcade game categories of the app store earning them nearly $2k in a week.

Here’s a quick summary of the formula they came up with:

  1. Presentation – Definitely looks are the most important factor that you can actually control.
  2. Uniqueness – The author emphasizes this, and it seems to be a factor, but I have seen a lot of rehashed stuff get featured so I’m not too sure about this one.
  3. Time of release – Interesting stuff here.. definitely seems like on some days Apple has slimmer pickings on some days as opposed to others.  Their suggestion is not to get your app listed right after the weekend if you want to get featured.
  4. Make The App Paid – According to the author Apple typically only features free apps by big publishers.
  5. Get Mentioned By The Big Sites – Apple seems to favor apps featured on big sites by Engadget (I would say though that these are usually only quality apps anyways 🙂

Interesting stuff, and you can read the full article here.

I would say that it is 90% luck, 9% presentation, and 1% the other stuff, but definitely some things to consider.

Custom UIView Tutorial – 5-Star Ratings View


There are many iPad and iPhone apps where custom ratings could be useful, such as news apps, and picture rating apps.  The problem with programming a custom UIView is that it is a pretty laborious process, and it’s easy to get something wrong along the way.

If you decide to go with the UIView approach, some of the tougher things are having the ratings follow along with your finger, and displaying the correct number of stars.  You may have noticed when browsing the web that some of these don’t work at all on iOS devices.

Building The Custom UIView

Ray Wenderlich,  the creator of the Space Game Starter Kit and co-author of the Learning Cocos2D book, has created an excellent tutorial on How To Make a Custom 5 Star Rating UIView that goes through the process of creating a custom UIView.  It is a bit laborious for something so simple, but it definitely works, and works well.

Ray’s guide is also very useful for just learning how to customize UIView’s for other purposes 🙂

A custom 5-star rating UIView is also included in the handy TouchCustoms library.

Big List of Youtubers Who Will Review Your iPhone App


As many of you may have noticed, I have been updating my older resource lists with updated links that have been shared with me in the last few months since starting this site, and I’ve been uploading tutorials/other videos to Youtube.

One resource which I didn’t really think about was Youtube.  I wasn’t really a Youtuber before uploading my videos, but something I noticed was that there is a massive number of people on Youtube doing app reviews.  Usually developers will upload a usage video to Youtube, and ultimately that’s the end of things, it’s hit or miss, and most videos get very few views.  

Why not send the App reviewers your apps?  Many of these reviewers have already established a subscriber base of 10,000 or more on Youtube (along with nearly as many on Twitter), and I’m sure would be flattered if sent a promotional code.  A couple who I have contacted seemed very excited about the idea.  Also, many of these videos end up being shown on other sites so the effect can multiply.

I wouldn’t be turned off it appears that many of these viewers are members of the younger set, after all this is a large segment of the App market, and especially if you’re developing an entertainment app this likely is your market.

Onto the list, I’ve sorted the reviewers here by the number of subscribers each has to their channels.  If you have an ACTIVE channel that I have not listed here please post it below, and I will add it to the list. 19,040 Subscribers. 16,237 Subscribers. 13,420 Subscribers. 12,645 Subscribers. 8,197 Subscribers. 4370 Subscribers. 3,697 Subscribers. 3,504 Subscribers. 2,892 Subscribers. 2,475 Subscribers. 2,282 Subscribers. 2071 Subscribers. 1447 Subscribers. 653 Subscribers. 552 Subscribers. 536 Subscribers. 532 Subscribers. 335 Subscribers. 279 Subscribers. 226 Subscribers. 211 Subscribers.

Don’t forget to mention if you have/know of an active channel in the comments.

Thanks for reading.
