Instinct Solar - 4 months old. Accuracy when tracking an activity like walking or running is fine (within 500 steps or 0.5km) when worn concurrently to Apple Watch3. But when wearing just day to day in/out the house and not specifically tracking any activity, the step count and distance covered is massively different - ie 2-3000 steps different and 1/2 the distance! .. what am i missing here?! as it's very frustrating and means i can't abandon my Apple Watch for daily non activity tracking
