What's the buzz in the AppStore

Rob ★★★★
Version – 1.4.4

I teach medical simulation and resuscitation every week. Sometimes I just want to run a simple scenario without all the high fidelity expensive kit and wires. SimMon is perfect for this. It adds realism to your training but is very simple to use and can be taken anywhere in the hospital. Just place your iPad next to a patient actor or manikin and off you go. If you have another apple device link it with your monitor via bluetooth and you have a remote control. The technology has never failed and the candidates really enjoy having the simulated patient monitor screen. We often use it on Resuscitation Council (UK) courses and ALERT courses for deteriorating patient scenarios. If you have an iPad and teach regularly it is worth the investment.

Amazing! ★★★★★
Version 1.4.4

This is an amazing piece of software, it allowed me to do simulation for my residents without the high fidelity mannequins. […] I loved the ease of using my iPhone as a Bluetooth remote!

- DMedo

Fantastic app to improve contextual fidelity of simulation ★★★★★
Version 1.3.2

This series of apps (iPad and iPhone) was the perfect solution to add a simulated patient monitor to our neonatal resuscitation training. Very easy to set up and use. The developer is very responsive to feedback and has made many improvements in the short time I have used it. This is a great alternative to investing in very expensive patient simulators. I highly recommend it.

Fantastic portable Teaching Tool ★★★★★
Version 1.3.10

I would highly recommend this for any clinical educator. What a great teaching aid for Mock codes or ACLS and PALS. Very easy to use and very receptive from students. Can’t wait to see what the updates bring, this app can only get better. Their customer service is outstanding as well!!! Keep up the great work!!!

Docslc ★★★★★
Version 1.3.10

Fantastic app for a great price. Easy to use and can be controlled from second iOS device. Different wave forms available for each parameter, and prompt offline support. Well done on making a great app. Highly recommend it for anyone involved in medical/nursing education. (my kids love it too).

Frequently Asked Questions

And their answers

What can I do with the app?

SimMon is a simulated patient monitor for basic medical simulation – Dr. Jon Gatward’s MobileSim website and “Guerilla Sim. Anytime. Anywhere. Anyone.” podcast does a great job of explaining mobile medical simulation.

Can I issue my staff redeem codes?

Yes! If you use the Apple Volume Purchase Program your staff can then use the redeem codes in the iTunes AppStore to download SimMon without using their own credit card.

Do you offer educational discounts?

Yes! If you use the Apple Volume Purchase Program you will get a discount on volume purchases for qualifying institutions.

Do you offer volume discounts?

Yes! If you use the Apple Volume Purchase Program you will get a discount on volume purchases.

How do I connect my devices?

Your two devices must be connected to the same WiFi network or directly via Bluetooth.

If your devices are not able to find each other the most likely cause is the configuration of the WiFi network. Some institutional networks shield the connected devices from each other for security reasons. So even though you are able to connect to the internet, you are not able to connect two devices or computers on the network to each other.

We recommend three alternative methods of connecting the devices:

1) Turn on Personal HotSpot on your iPhone. Personal HotSpot create a private WiFi network on your iPhone that your iPad can connect to. Other user reports that Android WiFi hotspot on HTC Wildfire also works just fine as does creating an ad-hoc network on a laptop. This alternative is the way to go when you have an iPhone.

2) If you repeatedly find your self without a usable wireless network I recommend buying an Apple AirPort Express wireless base station to create a wireless network. The Airport Express can be used as a local wireless network without connecting it to the the internet (which might be against network policy).

3) You can also use Bluetooth to connect the devices. Enable Bluetooth on both devices and allow extra time for the devices to discover each other.

Can I try SimMon before buying?

Promo codes for the iTunes AppStore are available by sending an e-mail to our support. We’ll send you a promo code as long as the are available from Apple. As per Apple guidelines the number of promo codes are for evaluation and non-commercial use only.

I have more questions!

auckland HEMS

Auckland HEMS resource page includes SimMon

Auckland HEMS has a great Prehospital Simulation Resources page that mention their use of SimMon.

ARHT has iSimulate equipment which is not yet fully operational; in the interim a simple app like SimMon can add extra fidelity.

The stated purpose of the page is to act as an online repository of simulation scenarios that will be regularly expanded with the aim of building a useful clinical resource – and it certainly does that well.

The page contains scenarios that are free for anyone to use and adapt as they wish under FOAM (Free-Open-Access-Meducation).


Great review of apps for simulation

Dr Tim Leeuwenburg (@KangarooBeach) and Dr Jonathon Hurley (@DrJHurley) has published the best review of simulation apps to date.

Tim is a rural GP-Anaesthetist in South Australia and a passionate advocate of ‘guerilla sim’ and Jonathon is an EM trainee in the UK and keen on human factors and simulation in EM.

Really through and well executed review – and SimMon gets a mention too.


SimMon at Auckland HEMS

Rossi Holloway is a 5th-year medical student who works with Auckland HEMS doctors on their simulation scenarios. She wrote an excellent article available at the Auckland HEMS site “A medical student’s perspective at Auckland Rescue Helicopter Trust“. Rossi mentions SimMon as part of the simulation set-up at Auckland HEMS:

[We use] SimMon (for iPad), which can be set up to look like a regular monitor and will make appropriate noises when remotely controlled from iPhone (including that sweat-inducing desaturation beep).

Informationweek Healthcare features SimMon

InformationWeek: Mobile App Teaches Clinicians To Monitor Patients

The lovely Michelle McNickle, Associate Editor of InformationWeek Healthcare, wrote at nice article on SimMon.

I’m glad to see the initial costs of simulation hardware come down through the use of already existing hardware most people are able to get a hold of. Hands on training is an invaluable part of training and will help clinicians spot trends in vitals and other real-time patient data.

TechTrends highlights SimMon as inexpensive high tech medical training

[…]SimMon, when combined with a low fidelity mannequin can create an inexpensive high tech medical environment for training purposes. […] The app can simulate a range of medical scenarios for health care professionals and students to gain experience and practice.



iMedicalApps recommends SimMon

Tom Lewis editor at iMedicalApps has written an awesome and comprehansive review of SimMon.

iMedicalApps is a leading online publication for medical professionals written by physicians and analysts. iMedicalApps is recognized as experts in mobile health by the New York Times, Wired Magazine, Slate Magazine and many others.


SimMon is a great example of the educational potential of mobile technology. This is a good app for simulating a range of scenarios but there are a few improvements that would enable it to compete with some of the more technical medical simulators.

SimMon Nominated as Best Science & Education App

Wow! We are really proud to announce that SimMon is nominated as best Science & Education app in the 2012 Danish App Awards.


SimMon is featured on Australian TV

SimMon gets it’s television debut on Australian Sunrise show hosted by Simon Reeve. Still in the dark as to who made it happen – thank you mysterious Aussie!


SimMon is featured in UCC Magazine

SimMon is featured along side a spread on Maj Siercke’s Hillerød Clinical Simulation Lab in the October issue of UCC Magazine.

The Clinical Simulation Lab in Hillerød was one of the first simulation labs to use SimMon and it’s great to see the lab (and app) get some good publicity.

Maj Siercke is an associate professor at the UCC School of Nursing and in addition to being an experienced nurse has a background as both a coach and certified facilitator. She also consults at The Danish Institute for Medical Simulation (DIMS) in Herlev. We’re glad to have Maj Siercke on board as a beta tester and value her suggestions and even bug reports. Thank you!


We love to make new friends
