The Honeywell MicroRAE app duplicates the experience of operating a MicroRAE handheld gas monitor. It comes with an interactive tutorial, which simulates navigation through the MicroRAE user interface via the same buttons and display as an actual instrument. By default, the app shows normal readings for configured sensors. With the Honeywell MicroRAE app, you can: - Familiarize yourself with the instrument and its functional features - Review key product features and specifications - Simulate sensor readings and alarm conditions - Review in-the-box and additional accessories - Provide feedback on the instrument and mobile app
iAssign

- Automatic site assignment via beacons
- Proximity alerts for restricted areas
- Manual worker check-in/out
- Gas detection data interpretation
- Bluetooth-enabled tracking
- Enhanced worksite visibility

Know when and where workers were exposed to dangerous conditions and gain visibility into unsafe worker behaviors using iAssign® Technology and the Ventis® Pro Multi-Gas Monitor. iAssign® Beacons and iAssign® Tags make it easy to automatically track what’s happening on a worksite and interpret gas detection data without the need for wireless connectivity. iAssign Beacons automatically assign site names to Ventis Pro monitors based on proximity, helping safety managers to make sense of datalog information. Using Bluetooth technology, iAssign Beacons provide an added layer of safety and security by alerting users when they have entered restricted or dangerous areas. iAssign Tags allow workers to manually “tap in” and “tap out” of a location which allows anyone reviewing the data to easily see who had the instrument and where the operator was using it, making the information more actionable.

Verdict
The clearest difference is update cadence: iAssign at every 4 months against MicroRAE's every 18 months. MicroRAE's advantage is iOS requirement (8.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.
