Read full description

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 call

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.
