iOS App Preview Video for HeartCharts 2.3

Information about Apps available in the App Store can now include a video app preview…if you have iOS 8 and Yosemite.  Apple has made it easy to create the video using Quicktime to record directly from your iOS device, then iMovie to edit (including sound) and to export the final product.  So I made a video, as shown below, and Version 2.3 is now “up for review.”


Hypertension will be the subject of the next HeartChart. I am almost done…just a few popover text views to finish. This chart will use a long scroll view, to put more information on one page, and to simplify iPad rotation. Seems to be working out fairly well, though setting all the “constraints” in a scrollview seems more complicated than it should be. In addition to adding Hypertension to HeartCharts, I’m thinking of bring out this section as a standalone free app, so people could use it as something like a “free trial.”

HeartCharts 2.0 approved and available

Wow! Version 2.0 was submitted to the Apple App Store on 12/18/13 and approved on 12/20/18. Surprisingly quick, maybe because they were working overtime before closing iTunes Connect for a 5-day Christmas break. iTunes Connect is the developer site where you manage your apps, including submitting new apps and updates. You can also check the number of app sales by date and by country, and review financial reports to see how much you may have earned. So now I’ll update with up-to-date images and start thinking about 2.1 (maybe “Hypertension” and “Congestive Heart Failure”?).


Upgrades: Mavericks, Xcode 5, iOS 7, HeartCharts 2.0

The last couple of months upgrades were needed to run the latest version of Mac OS X (“Mavericks”) and the latest Xcode (5.0). This seemed to stress my 2007 MacBook Pro. Problems included computer not booting, fan suddenly revving full speed nonstop and shutting down the computer, tending to overheat, and occasional other weird behavior. With various internet-search aided troubleshooting, problems were “solved” (for now?). Then suddenly (it seemed) the hard disk was full, and I had to work at freeing up a lot of disk space…supposedly should have at least 15 GB free…Omnidisksweeper (a free program) was a major help to accomplish this, and I should run it periodically. So the MacBook seems to have settled down fairly well, though I probably should get a new one next year.

Xcode 5, needed for programming for iPads and iPhones using iOS 7, has been less problematic. It’s actually a big improvement, with some things being much easier. Like “autolayout” and “code signing.”

Next came HeartCharts 2.0. I just submitted it to the App Store today. I hope it gets out before Christmas, but might not, since Apple is closing the review process for a week. 2.0 looks a little different because of iOS 7 (which is required), but not much. I added chart for myocardial ischemia and infarction, and an image for clot in the left atrial appendage, as well as some aids for navigation. Next blog post will come after this version is approved and available! At that time I will also update the page describing HeartCharts.


Version 1.1

Version 1.1 has been completed, sent to Apple, approved, and on now on the App Store to download. This version added a chart for Aortic Regurgitation, in the Valve Disease collection.

This upgrade was made more complicated because the Apple Developer online site was largely taken down for a while, apparently after some hacking event. So some stuff which should be automatic was made a lot more difficult. For each App, Apple requires what are called “Certificates” for development and distribution, as well as “Provisioning Profiles” and “code signing.” Information about the App and the developer has to be coordinated online, in the testing device, in Xcode, and in the App Store. All of this is for protection, but makes things complicated, especially having to do it manually. But the documentation was relatively easy to follow, and I ended up learning a lot and understanding it more by having to go through the process. Future upgrades (which will be coming!) should be much easier.

I did find one mistake! When the new version is opened on the iPad, the home page still indicates “Version 1.0.” I forgot to change that text. So the next version will go from 1.0 to 1.2. Everything else seems to work OK. (I haven’t received any reports of problems or any suggestions from anyone yet).

One Week in the App Store: International!

Apple has a nice system for following detailed stats about your App’s sales. I was happy to see the there were some sales in the first week! But most interesting was that there were sales all around the world, in every continent (except Antarctica).

HeartCharts sales have occurred in these countries: USA, UK, Spain, Germany, Sweden, Netherlands, Japan, Taiwan, Mexico, Brazil, Australia, Israel, and Nigeria.


HeartCharts iPad App now available

I received an email from Apple at 1:15 AM on 7/12/2013:

“The status for your app, HeartCharts (669797925), is now Ready for Sale.”

Interesting that by the next AM, 3 individuals had downloaded the app…from Brazil, Netherlands, and Taiwan.

Now time to work on some new charts to add (I’m thinking Pacemaker, Myocardial Infarction, and Aortic Regurgitation).
