New Year Developments (January 2020)

Heart Analyzer really had a fantastic 2019. There’s no better way to sum it up than that. I’d like to take the opportunity to again thank all those who have downloaded the app, emailed in feedback and supported us with the in app purchases.

We’ve now reached the end of our development board for Heart Analyzer Version 7. It has brought to the app features such as the new Heart Home, Heart Reports, a brand new Apple Watch app and support for more metric types to name a few. Today we’re rolling out a bug fix update and we will continue to support the app in the time going forward. But we are now focusing on something new.


At its core, Heart Analyzer has always been about providing clear, intuitive and pleasing visuals of the users heart rate data. Across the board we believe it has achieved this goal whilst giving users insight into data they didn’t even know was recorded! However, we’re always looking for ways to raise the bar on these three things as well as making the app more accessible for our users. After some careful thought on how we could meet this, as well as gathering feedback from our users, a journey has now started towards re-designing Heart Analyzer’s user interface.

This will be a total overhaul for the iPhone app.

This will raise the bar on the apps core goals of delivering clear, intuitive and pleasing visuals of your heart rate data.

This will maintain all the app principals such as on device processing, no 3rd party analytics, no subscriptions. Our premium features will be developed, but previous purchases will, of course, be valid.

This journey will take some time. Yes, yes, how long you ask? W’d like to be out there beta testing in the Spring, and we are aiming for a release late Spring / early Summer.


We hope you’ll really love what we’re developing. Stay tuned for the January PT.2 Technicals blog to get more details on how the app is really changing behind the scenes. For now, all that remains is to leave you with some renders of our new Dashboard. Any feedback on this would be welcome, you can email any time via

All the best



Heart Analyzer V7.2 Release (December 2019)

I just thought I’d write a small post today to thank all the users of Heart Analyzer. The praise received for the new watch app has been amazing. The app has been picked up by so many sites and to name a few, these have included:

  • 9TO5Mac
  • MacRumors
  • iMore
  • BGR
  • AppAdvice
  • Engadget
  • iDownloadblog

It mean so much to have coverage from sites like these and it really helps get to the broader audience that the app is designed to help. Going forward Heart Analyzer will continue to strive towards making the most clear, understandable, visually pleasing and privacy focused app possible.

One last thing, this release would not have been possible without our fantastic beta testers who volunteered to help and provided excellent feedback. For this you have my greatest thanks.

All the best


Heart Analyzer V7.2 Beta Now Available! (November 2019)

Today we are delighted to launch a public beta for the brand new Heart Analyzer Apple Watch app. We released version 7 of Heart Analyzer earlier this year and at that time, we signalled that a brand new Watch App was on the horizon. We’re so excited that it’s finally here!

The biggest question that I’m sure you’re all desperate to know is, what’s changed? What’s new? What’s better? Well technically the answer to that is everything. The app has been re-written from scratch making use of brand new technologies in WatchOS 6 including SwiftUI. SwiftUI has allowed us to make more fluid, intuitive and interactive interfaces. We hope you’ll find this new app easy to navigate and quicker to get you to the information you’re after. You’ll also find more detail than ever on your heart rate data. The list of changes is near endless and I could write for pages here about all that’s changed and how its better, but I won’t. Instead, please just see the release notes below and get cracking with the app!

It’s worth mentioning a key detail for our users who aren’t on the latest WatchOS 6. We are delighted to announce that we have been able to maintain both apps in Heart Analyzer package. This means that users with an older Apple Watch or who have not done a software update, will still be able to access the original Heart Analyzer Watch app with a hand full of new fixes.

We are of course after feedback and welcome any requests or suggestions at this stage. Whilst they may not make the initial release, we are continuing to develop Heart Analyzer on iPhone and Apple Watch.

All the best



Heart Analyzer V7.2 Coming Soon! (October 2019)

Remember when we launched Heart Analyzer Version 7 in August!? Yes it seems ages ago to me too. Anyway, I’m delighted to say that the wait for the new Heart Analyzer Watch App is nearly over. Internal testing and finalising of features is already under way. I hope to start public testing within a fortnight and the current aim is for a release in the second half of November!

Thank you for all those who’ve sent in feedback to help us scope this release, we can’t wait to hear what you think of it. If you’d like to pre-register interest for the beta test, please ping us an email via with “Heart Analyzer Beta Tester” in the subject.

All the best


An Update on Heart Analyzer (September 2019)

I thought that now version 7 of Heart Analyzer is out along side iOS 13 and WatchOS 6, it was a good time to reflect as well as provide an update on the plans for the future.

The main aim of version 7 was to dramatically increase the data available to new users as well as improve the clarity and the accessibility of the app for users of all experience level.

As a reminder, we introduced:

  1. A new Heart Home
  2. Monthly Heart Reports in an exportable PDF format
  3. Support for VO2Max and Heart Rate Variability
  4. An improved Dashboard with a new card design
  5. Updated Metrics and Deep Analytics graphs
  6. Support for Workout Zones and Heart Rate Recovery
  7. Listed as coming soon to the wrist!

We’ll get back to that last one, but for now I just want to touch on the others. The new Heart Home has been a fantastic success and users are loving the Heart Reports. I’m really keen to continue to get feedback but an option for expanding Heart Reports in the future would be through having a second page with more advanced analytics, potentially straying into heuristic detail might be on the table. The data that the Apple Watch produces is so powerful, who knows what will be possible as people build up a greater history of health data.

All the other features introduced in V7 have received great feedback. However, I think some users may still not find the Dashboard as clear and visually pleasing as it could be. I’m always looking for new ways to clearly show the user each day of data in a scrollable form to allow then to go back through it. I think there may be better ways to achieve this, although it will require significant redesign and overhaul next year.

Back to that missing feature on the wrist. Yes, we are planning on releasing a brand new Watch app in November. For those more in the developer world, Apple introduced SwiftUI this year and the potential for the watch is astounding. We’ve already done some amazing mockups of a new app for the Watch with great graphs and short concise metrics for your day. It’s because of this that we will be adopting this new technology and the Watch app will be WatchOS 6 only. Luckily, all devices that support WatchOS 5 also support 6 but this does still seem like a steep requirement to expect. I hope that the results will be worth is for our users. We’re looking forward to starting public testing at the end of October, please get in touch if you’re interested. The iPhone app will continue to support iOS 12, although to install the Watch app you’ll need to be running iOS 13.

We will also be adding support for the new Always On display in the Apple Watch Series 5. This should make it clearer for customers to keep up with heart rate on the go. I’m excited by the hardware Apple announced this year, although I do keep my fingers ever crossed for continuous heart rate reading one day, or possibly just a bump up from around every 5 minutes readings to every minute. I appreciate this would have a battery life impact, but it would add even more to apps like Heart Analyzer that display the data.

I just want to address our recent version 7.1 release. This update brings support for the latest iOS 13 and WatchOS 6 update which include a lot of changes. We have had a small number of users experiencing issues here. Please do bear with us, we’re learning as you do of all the changes to the system and new hardware. We hope to have a fix release out really soon to address this.

Finally, I just want to mention Fitness Friend and Helix Apps. Heart Analyzer’s success has caused Fitness Friend to be slightly neglected int he past 12 months. We hope to release a bug fix update soon and with any luck we’ll get the time next year to work on a new version of that app including support for new health types. As for Helix Apps, this is now the sole proprietor of Heart Analyzer and Fitness Friend. We have exciting plans for the future including ideas for a fantastic new app, if only we get the time!

All the best


Heart Analyzer V7 Now Available (August 2019)

Today, after years of customer feedback, many months of development and weeks of Beta Testing, we are releasing Heart Analyzer V7. I would be delighted if you’d consider checking the app out and potentially writing about it at MacWorld!

The app is now available to download here.

What’s new:

New in version 7, the app can now produce monthly PDF reports on a users heart rate data. This regular metric, that the user can export, is inspired by the current Apple Watch ECG reports that can be exported in the Health App. We really hope our users love these and go back to the app on the first of every month to view the new report!

Alongside this, there’s a new Heart Home in the app where users can get more personalised metrics. Details such as maximum and minimum heart rates, Cardiac exercise levels and VO2Max let the users understand their readings and fitness based on their age and biological sex.

The app has also been significantly updated to provide a more simple user interface and experience when ever possible, whilst also maintaining and often increasing detail! This feat is achieved through new card interfaces and natural gestures. We hope this will allow Heart Analyzer to be useful to users of any level, be it new to their heart rate data, or an avid user who checks it daily to see their trends!


We really hope you enjoy this fantastic release. As always, please get in touch if you have feedback and consider leaving us a review to spread the word!

Thanks, Simon
