Common questions
- How much does the Coros Apex 4 cost?
- The Coros Apex 4 starts at $429, with larger sizes and premium finishes costing more.
- Does the Coros Apex 4 require a subscription?
- No. The Coros Apex 4 has no subscription — you pay for the hardware once and the Coros app is included.
- How long does the Coros Apex 4 battery last?
- About 24 days of typical use per charge. Heavy GPS use, an always-on display, and continuous sensing all pull that number down.
