Explore diseases and conditions of the gastrointestinal (GI) tract and perform surgical procedures on virtual patients with our newest video game for medical professionals, Gastro Ex.

Our fully-responsive patient anatomy allows you to perform hyper-realistic GI procedures: remove polyps using snares and forceps, treat AVMs and bleeds using APC, perform biopsies, administer injections, and much more.

In Gastro Ex, you can:

- Get scored in real time for accuracy, speed, damage, device competency, and diagnosis skills while performing endoscopic procedures in the app.

- Earn CME credits while playing this first-of-its-kind professional video game for practicing gastroenterologists.

- Earn the highest score and invite colleagues to play our realistic patient cases: Atypical Angioectasias, Surprising Sigmoidoscopy, Polyp Hunt, Lurking Lesion, and more.

- Explore the medical cases that impact millions of adults every year through cutting-edge video game visual effects.

More about Gastro Ex:

Our app provides unprecedented medical realism, enabled by the accurate simulation of human tissue dynamics, realistic scope optics, and moving fluids to recreate life-like endoscopic procedures in the GI tract. Each case is vetted by top gastroenterologists and medical experts with clinical simulation training experience from top hospitals.

Gastro Ex simulates GI tract procedures that millions of adults will have in their lifetime. According to the CDC, adults 50 years and older should get screened for colorectal cancer given the increased risk in this age group. More than 90% of colorectal cancer cases occur in people aged 50 or older, yet only 50% of adults who should have colonoscopies comply with recommended guidelines. The simulations in Gastro Ex make many of these screening procedures, polyp removals, biopsies, and more readily accessible at your fingertips for advanced training.

Great Training Tool however...


This “Game” is a great training tool! Very realistic and a great way to practice procedures however, the game causes INTENSE overheating of iOS devices. I was using this app and it caused my iPhone 6S to overheat to the point where the device fried itself and no longer functions. I purchased a new phone, the iPhone X, after about 3 minutes of playing this game, the phone began to heat up. So I’ll be deleting this app as well as the Intubation app as well. If you guys can fix the amount of use this app needs on devices, I’ll totally download again.

Thank you for letting us know. Our development team is working on improvements to this issue. Generally, this should not happen on a newer device. As we work to improve this, if you close the app ever 15 minutes of play, this should help your phone. Feel free to reach out to us at with any additional concerns.

Add one thing


Love the app I really do but can you add screen rotation when I charge my phone when playing the screen doesn’t flip so it’s hard for me to charge my phone at the same time and play my game and I can’t my my charger because this is the only plug I have closest to me in my room

We always appreciate suggestions so thank you very much for your feedback! We shared this feedback with our development team.

Awkward but it's really cool


I, uh, didn't realize this was meant for training nurses and things, it just looked cool so I tried it! And to learn medical stuff I suppose. I know next to nothing about gastrololgy (?) but I've been doing a decent job... Somehow.. 😂
Anyway devs I kinda feel bad cause I just kinda jumped on without realizing ^^; but it's great!

We’re glad you’ve enjoyed the experience. You’re absolutely correct! Gastro Ex was created to train healthcare professionals and the cases continue to get more advanced as you continue through the app.
