SimMon vs Nerbio iTOF
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SimMon
This app provides a remotely controlled simulated patient monitor for medical training. It allows users to adjust vital signs like blood pressure and heart rate on one device, displayed on another, facilitating realistic simulation scenarios.
- Remote patient monitoring simulation
- Adjustable vital signs (BP, SpO2, HR, RR)
- WiFi and Bluetooth connectivity
- Simple setup and operation
- Dual-device functionality

SimMon is a basic remote controlled patient monitor for full scale medical simulation. Using SimMon on any pair of devices, iOS 13 or newer, gives you a simple remotely controlled simulated patient monitor. An iPad makes for an ideal multi-touch controlled remote and the big screen makes a great bedside patient monitor. Open SimMon on your two devices of choice and connect via WiFi or Bluetooth. Change the blood pressure, oxygen saturation, respiration rate or heart rate by touching the value and dragging your finger up or down. Simple setup. Easy operation. Low cost. Thank you for the amazing feedback and support - it keeps SimMon evolving!
Nerbio iTOF
This medical application works with a specific device to provide quantitative monitoring of neuromuscular blocking agents. It enhances patient safety and accuracy in monitoring, offering wireless control for caregivers. The system is recommended by anesthesiologists for precise neuromuscular transmission monitoring.
- Quantitative neuromuscular transmission monitoring

Nerbio’s iTOF® app works with the iTOF device; an FDA cleared, quantitative neuromuscular transmission (NMT) monitor for remote monitoring of neuromuscular blocking agents (NMBAs). The iTOF app is designed to make patient monitoring safer, easier to use, and more accurate than ever. The iTOF is the first mobile device-managed, quantitative monitor of NMBAs. The combination of the app and Bluetooth-connected stimulator device allows precise, automated quantitative monitoring of the level of neuromuscular block. Wireless control also improves caregiver safety while maintaining a high-level of patient care. The iTOF system is recommended by leading anesthesiologists and used around the world for accurate NMBA monitoring. ------------------------------- NOTE: This app requires the iTOF device hardware to perform monitoring.

Verdict
The clearest difference is price: Nerbio iTOF at Free against SimMon's $22.99. Nerbio iTOF also leads on rating (5.0 vs 4.5) and update cadence (every 2 months vs every 5 months). SimMon's advantage is chart position (#176 vs unranked) and ratings volume (13 vs 3). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
