Emergency services widely use the METHANE acronym to build a report for alerting others about a major incident. The METHANE format is taught widely, and may seem easy to remember, but in a crisis is often difficult to recall at the very time that it is needed the most. The risk is therefore that the METHANE message is never sent, with subsequent delay in an appropriately-scaled emergency response. Prometheus IMT METHANE aims to be an intuitive, simple, quick and reliable way of building a METHANE message in a major incident situation, or an ETHANE message in a complex incident (i.e. a lower tier of incident where the essential components of the message are still very useful). Prometheus IMT METHANE has been designed and develop by highly experienced emergency responders who still struggle to have the right fluency with the METHANE message when under extreme pressure. This is a tool designed to meet our needs. We believe others out there share those needs. Please let us know how we can make it better.

The iOS app for the information and operation system IES enables a fast collection and administration of patient data (online and offline). The integrated recognition of driver's licenses, passports and ID cards ensures high efficiency. In addition, photos of people and other documents can be uploaded directly from the app. The use of the app requires an active user account on the IES platform as well as corresponding event authorizations.

Verdict
The clearest difference is in-app purchases: IES at none against IMT's 3. IES also leads on update cadence (every 2 months vs every 4 months) and device support (3 vs 1). On price and ads there is nothing between them.
