Price, ratings, monetisation and update history for both apps, side by side β with what reviewers say about each.
iTEM
Read full descriptionHide full description
The iTEM app is designed specifically for health professionals to enhance their knowledge and understanding of Rotational Thromboelastometry (ROTEM). This app is an educational tool, providing a training module covering the fundamental principles of thromboelastometry, ROTEM assays, and parameters. With this module, healthcare practitioners can access detailed information on interpreting ROTEM traces, enabling them to make informed clinical decisions. In addition to the training module, the iTEM app offers an algorithm module, which is slated to be released in the near future.
TEGRotem
Read full descriptionHide full description
This application cannot be used by the general public in managing any health condition. It is designed to teach specialist doctors how best to interpret viscoelastic testing results obtained from the TEG and Rotem devices, so that they may better understand the likely causes of bleeding disorders. It is not designed to influence clinical judgment. The algorithms are based on a wealth of publications in the medical literature for processing TEG and ROTEM data. The structure of the algorithms used in this app is very important, simplifying bleeding management to a stepwise approach following a physiologic process. These algorithms have been devised as a teaching tool for ease of comprehension and simulation training. See the following references for further information: : 1.

Verdict
The clearest difference is price: iTEM at Free against TEGRotem's $0.99. TEGRotem's advantage is update cadence (every 4 days vs every 5 months) and chart position (#193 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
