Availability dateWhen an iPhone application submitted to Apple iTMS there are pages of information to fill out. Among the forms is a strange setting called "availability date". Developers can use it to set their application for release on a specific date in the future. Say you submitted your application on Monday, you could hedge a bet that it will only take a few days for Apple to review, and then you could setup a Friday launch.
When we launched iSkream there were about 6,000 applications in the store. At the time, one of the ways small developers would try to get their application a moment in the spotlight was to get into the "new applications" featured category. The trick was to time your availability date perfectly so it would appearing during what seemed like a week update by Apple to the category. That's largely an irrelevant strategy now. There are simply too many applications being submitted daily.
Submission dateSubmission date is very important and not well understood by many in the community. The submission date is fixed at the time of your original submission in iTunes Connect. A developer can go in to iTunes Connect to grab the application name and fill out all the ERSB information, pricing, and description. You can think of this as either getting your ducks in a row or as name squatting. Steamboat Mountain Designs has dozens and dozens of applications sitting in this state.
What isn't well understood is the relation between the submission date and iTMS ranking. The bottom line is that an application is loosing rank everyday it isn't selling. The store rank system looks upon this situation as if you're simply selling no applications. Yes-- even if it isn't really available in the store.
So there is a catch 22 here. If you grab the name early you're loosing rank. If you don't grab the name you risk getting the application rejected because of a name availability. Quite a hassle for your artwork, sound, and binary. Keep in mind that simply because the application doesn't appear in iTunes doesn't mean the name is available.
With iSkream we discovered that the original name iScream was already taken. We had to spend a day rebranding everything including the website. What we got in return, and didn't even realize was the benefit of a quick turn around from submission date to availably. Take a look at how the iSkream ranking starts off high in the MobClix graph to the right.
Having thought we learned the iScream lesson, we grabbed the iTunes Connect slot for Abby Crabby shortly after the concept came about. What we didn't realize was the downside in forcing a month window of time between submission date and availability date would give us a softer launch. We'd have to build some momentum on our own through marketing techniques. Take a look at how the Abby Crabby rankings launch soft and we slowly gain over time.
