You may wonder how much will the Aura Ring 4 cost you. The base price is $349 and there also is a monthly fee of $6 for the subscription. However, if one decides not to subscribe, they will only receive basic activity, sleep, and readiness scores while missing out on several vital features. Some may believe that more features should be part of the package from the beginning, especially because other wearable companies, such as Samsung and Apple, do not require a subscription for more features. It may actually depend on how important the unique features and design of the Aura Ring are to you as to whether or not the price is worth paying.
