    • The BBT-113AI needs 60s (which is already faster than other basal thermometers) for 2-decimal precision, crucial for detecting tiny post-ovulation temp changes in fertility tracking. Regular ones are quicker but less precise.

    • No. The BBT can’t connect via Bluetooth to your phone. However, you can manually transfer your temperature to any app or keep track of your on paper.

    • It is best to measure your temperature with the BBT thermometer around the same time every day. The most accurate will come from measuring before getting out of bed, right after waking up. Your body temperature will be at its lowest during this time.

    • Yes. The BBT thermometer is developed to track your basal body temperature. Only a BBT thermometer is. It’s far more accurate and measures two decimals. This allows you to determine the increase in your temperature needed to detect your ovulation.
