On-Screen Scientist

Apple has just introduced the ability for app developers to bundle multiple apps on the App Store into a single package priced below the cost of the individual apps purchased separately. And if you’ve already purchased one or more of the apps in the bundle, you can apply what you’ve already paid to the cost of completing the bundle. This Complete My Bundle works just the same as the iTunes Complete My Album feature for people that have bought one or more songs off an album and want to download the rest of it without paying what the sum of the individual tracks would amount to. This is a feature I had been wishing for and had even tried to figure out a convoluted ways of implementing myself via in-app-purchases. I’m very glad I didn’t, as it has all been taken care of beautifully now.

I’m delighted to announce OnScreen DNA Complete, which is a bundle of OnScreen DNA Model, OnScreen Gene Transcription, and OnScreen DNA Replication, our three iPad apps that show the structure of DNA and how it works in a cell, all using the same 3D interactive model with animations that are scientifically accurate, within the limits of the molecular model. The model has been chosen to show the essential molecular components and the double helix structure of DNA, unobscured by the atomic details of the molecules. See the following links for some reviews and descriptions of the apps.

Each of the three apps in the OnScreen DNA Complete bundle currently (9/18/14) sells for $4, and the bundle costs $9, which translates to a 25% discount. Purchasing the apps in the bundle is like getting two of them at full price and the third for only $1. Which is exactly what someone that already has bought two of the apps at full price will pay to get the third. Anyone that has bought one at full price, can get the other two for $5 total.

That means you can try one app, see how you like it, and then apply what you’ve already paid to the bundle price that gets you the other two. You don’t have to remember what you paid for an app, as Apple remembers for you. If you have already paid as much or more than the total bundle price, then you can download the rest of the bundle for free, which will be great for people that have bought apps before a big price drop. That won’t apply to the OnScreen DNA Complete bundle at this point, since the apps have not sold at a higher price, but it will for some other bundles. Apple does insure that the bundle price on any day must be less than the price of the component apps total price for that day, so there is no danger of a false bargain.

NOTE: As I write, there is an ugly bug in the iPad App Store app that makes full-screen views of the app screenshots associated with bundles look terrible. Believe me, our screen shots look great. If you want to see how the images look filling the iPad screen, go to the descriptions of the individual apps. Hopefully, Apple will catch this soon. I filed a bug report.

The apps have all been tested to work great under the new iOS 8 system without upgrade. Go get that OnScreen DNA Complete bundle!
