This study is looking at a device called the Eversense CGM System, which helps people with diabetes check their blood sugar. CGM stands for Continuous Glucose Monitor. This study will compare how well people manage their diabetes using the Eversense system versus a regular blood glucose meter over a year. For the first 6 months, participants will use a regular meter, and for the next 6 months, they will use the Eversense system. Participants will visit a clinic and use the device at home. The study involves two sensors, each lasting up to 90 days.

• The study lasts for 12 months with both clinic visits and home use.
• Participants must be 18 or older, have diabetes, and have a smartphone.
• Participants cannot be critically ill, on dialysis, or pregnant.
