Apple's smartwatch costs more and lacks essential features such as a SpO2 sensor. It also comes with a free six-month subscription to Fitbit Premium, after which users will have to pay $9.99 per month to get features such as advanced insights to tracked metrics, workouts and mindfulness sessions, a wellness report, etc. At $229, the Fitbit Versa 4 is cheaper than the Apple Watch SE 2, which starts at $249 for the base model with Wi-Fi + GPS. The Fitbit also has a fast charge – a 12-minute charge will provide a day of use. However, it is no match for the Versa 4, which has six-plus days of battery life. Regarding battery life, the Apple Watch SE 2 will last up to 18 hours on a single charge and go up to 36 hours in low-power mode. Fitbit's watch is also compatible with Android and iOS devices, while Apple's watch isn't designed to work with non-Apple devices. The two watches also have a voice assistant (Siri for the Watch SE 2 and Alexa for the Versa 4). There's a microphone and speaker on the Versa 4 for taking Bluetooth calls. Apple's watch also has optional LTE, so users can take and make calls even when their phone isn't on them. Both watches have Bluetooth 5, NFC for payment, and Wi-Fi. In addition, the two smartwatches have built-in GPS for real-time tracking when outdoors.Īpple bests Fitbit in additional safety features such as fall detection, crash detection and emergency SOS. Apple doesn't say how many the Apple Watch SE 2 is capable of, but it covers the most popular ones, including HIIT, yoga, Pilates and rowing. Fitbit says the Versa 4 can track more than 40 activities with auto-detection for some. Neither of the two watches has a temperature sensor, but the Versa 4 can measure skin temperature variation using existing sensors. It also has stress tracking and can measure breathing rate. On the other hand, Fitbit has equipped its watch with red and infrared sensors for blood oxygen saturation (SpO2) monitoring.

Unfortunately, the Apple Watch SE 2 also lacks blood oxygen level monitoring. The two watches also track heart rate variability (HRV), the time between heartbeats, sleep tracking and menstrual cycle tracking. Nevertheless, there is support for irregular (heart) rhythm notification which can also check for signs of AFib on the Apple Watch SE 2 and Fitbit Versa 4. In addition, the two watches have an optical heart rate sensor for all-day heart rate monitoring and will notify users if their heart rate is high or low.

However, Fitbit doesn't say what chip is inside its watch nor if the Versa 4 has built-in storage for playlists, podcasts and audiobooks. Apple says the Watch SE 2 is powered by the S8 chip and packs 32GB of storage for audiobooks and podcasts. On the other hand, the Fitbit Versa 4 has an AMOLED display with support for an always-on display. The Apple Watch SE 2 has a retina LTPO OLED display but doesn't have support for an always-on display.
