Version 2.4 is “ready for sale”

Version 2.4 adds a lot more information about atherosclerosis. This subject is a lot more complicated that the initial “chart” may have implied. I tried to give more recent information about plaque rupture and about how plaque forms.

Version 2.5 will probably be out soon…this adds a chart about Coronary Bypass Surgery.

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.”

HeartCharts 2.3

Finally, I’ve almost finished the next upgrade to HeartCharts. (Excuses: my old MacBook Pro from 2007 had to be replaced, and I upgraded to Yosemite, and to Xcode 6… I am liking all the new stuff!) HeartCharts 2.3 will add a new “General Cardiology” section, with 3 new charts: Dilated Cardiomyopathy, Hypertrophic Cardiomyopathy, and Hypertension. The new software upgrades allow video previews on the App Store, so I will do that… and plan to also post the video on this site.


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 1.2 — Pacemakers

Last week the V 1.2 upgrade was approved by the App Store. A chart on Pacemakers was added. It opens with a diagram/animation of AV sequential pacing (wires in both the atria and ventricles, pacing in both chambers). This can be switched to a system showing sinus rhythm, with the pacer tracking the atria, then pacing the ventricles. There are the usual labels leading to further discussion about multiple of topics, including the Pulse Generator, the Leads, etc.

As usual, upgrades to iPad apps are free.
