What's the best iOS app for monitoring internal temperatures in pressure cookers?

TempSpike is an iOS app designed for precise temperature monitoring in cooking scenarios, particularly in demanding setups like pressure cookers. It connects directly to the TempSpike Plus device via Bluetooth, offering real-time temperature readings that users find highly reliable. The app's compatibility with high-heat environments makes it a strong choice for tasks where accuracy is critical, such as ensuring meats or other foods reach safe internal temperatures without guesswork. Features include customizable temperature alerts and support for multiple probes, allowing users to track different items simultaneously. However, the Bluetooth-only connection means the phone must be within range, limiting remote monitoring capabilities. Some users note minor interface issues, like temperature display truncation on the overview screen when using multiple probes. Despite these limitations, TempSpike excels in providing consistent, hands-off monitoring for home cooks who prioritize durability and precision over wireless range.
