A good piece by Ellis Hamburger at The Verge, who explains why some recent iOS apps have been putting new users on a “wait list” before they can actually start using an app. This is due to the increasingly cloud-based complex scaling challenges that apps (which are downloaded locally) face when trying to work with online components (remotely) for thousands of users.

I understand the difficulties mentioned by Ellis and the developers he interviewed, but I also see part of Ben’s point when he argues that several of these “wait list apps” are free and don’t seek immediate revenue. Mailbox removed the reservation system after it had been acquired by Dropbox, meaning that Dropbox – a larger company – had the human and financial resources to “throw” at Mailbox’s problem. However, I think that resources aren’t a panacea for new apps that rely heavily on server-side features: if anything, the App Store makes it hard to ship apps that are only available to a subset of users, which is forcing developers to implement ideas such as the aforementioned waiting lists.

A better testing process for App Store developers isn’t a new topic, and I wonder if app testing tools made by Apple with support for thousands (instead of hundreds) of “beta” users would alleviate the issues covered by Ellis.

David Smith wonders whether today’s release of Logic Pro X as a new app sold at full price is the best explanation of Apple’s stance on upgrade pricing to date:

I’d say that this is the best indication of Apple’s intentions and expectations for the App Stores going forward. I wouldn’t expect anything like upgrade pricing to appear in the Stores. It seems like the message is to either give your upgrades to your customers as free updates or to launch a new app and charge everyone again. Neither approach is perfect but I am now very confident that this is the going to be the situation for the foreseeable future.

This is an issue that I’ve long debated with my teammates and developer friends. As someone who’s used to seeing upgrade pricing in Mac apps sold outside of the Mac App Store, I would welcome the addition of built-in upgrade pricing to the App Store. However, on the other end of the spectrum, our Gabe Glick neatly summed up Apple’s possible motivations last year:

Developers and longtime computer users may be used to the shareware, time trial, pay-full-price-once-upgrade-cheaply-forever model of buying and selling software, but regular people, the mass market that Apple continues to court first and foremost, aren’t. Adding demos (“I thought this app was free, but now it’s telling me I have to pay to keep using it? What a ripoff!”) and paid upgrades (“Wait, I bought this app last year and now I have to pay again to keep using it? Screw that!”) would introduce a layer of confusion and make buying an app a more arduous process, which would result in people buying fewer apps.

Today’s release of Logic Pro X is just another data point and it may not necessarily be conclusive, but I believe it further suggests how Apple sees the process of releasing major upgrades to Mac apps. It’ll be interesting to see if Apple will ever do the same for its (cheaper) iOS apps, though.
