TEE Standard Views vs ECHO On
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
TEE Standard Views
This application aids in learning transesophageal echocardiography by visualizing 3D cardiac structures from 2D echocardiographic images. Users can explore standard diagnostic views, rotate 3D heart models, and align them with TEE recordings to understand cardiac function.
- Visualize 3D cardiac structures
- Explore 20 standard TEE views
- Rotate 3D heart and probe models
- Align 3D models with TEE recordings
- Assess cardiac function

The primary challenge in learning transesophageal echocardiography (TEE) is translating the two dimensional echocardiographic image into a visualization of the three-dimensional (3D) structure of the heart. We have created this application to assist with teaching and learning the assessment of cardiac function with TEE. Users can view the TEE recordings for each of the 20 standard diagnostic views and see the corresponding 3D model of the heart, the TEE probe, and the ultrasound plane. Each TEE view can be selected from a menu at the left of the screen, or by using arrow buttons to go to the next or previous view in the list. For each TEE view, the 3D model of the heart, probe, ultrasound plane, heart can be rotated in the horizontal or vertical plane to view it from any angle. The part of the heart above the echo plane can be removed, and the heart model can be oriented so the structures correspond to the TEE image.

- Transesophageal Echocardiography education
- Enlarging question bank
- Rescue TEE cognitive aid
- Case Log system
- Perioperative Quick Reference library
- Offline echo loops
- Pathology, technique, and normal loop examples

ECHO On is a free medical education resource for learning Transesophageal Echocardiography including a free, enlarging question bank, a Rescue TEE cognitive aid, a Case Log system for submission to the NBE, and a growing perioperative Quick Reference library with offline echo loops that work even in the OR without internet access, and includes pathology examples, techniques, and normal loops of the heart. ECHO On will walk you through an entire standard 28 view exam teaching you the anatomy, function and Doppler interrogations you should perform at each view, and how to interpret them. ECHO On is and will remain free, and the best way you can contribute is to submit boards-style questions or echo stills and echo loops to help grow the QBank, Quick Reference and Pathology libraries. Disclaimer: This app was written to provide an accessible perioperative tool for residents and fellows learning TEE in the cardiac OR and ICU, and for generalist anesthesiologists looking to refresh their knowledge of TEE. It is not meant for patients to self-diagnose. It is not meant to be a definitive reference. Despite my best efforts, there may be errors or inaccuracies in this app, so please do not use it for medical decision making, as doing so may lead you misdiagnose or seriously harm your patient. If you are not a qualified medical doctor, please see a qualified medical doctor before making any medical decisions, including those based on echocardiograms.

Verdict
The clearest difference is price: ECHO On at Free against TEE Standard Views's $4.99. ECHO On also leads on rating (4.9 vs 3.8) and update cadence (weekly vs every 9 months). TEE Standard Views's advantage is iOS requirement (6.0 vs 15.6). On ratings volume, ads and in-app purchases there is nothing between them.
