iCan i6 vs FreeStyle Libre 2: CGM Sensor Comparison
iCan i6 has a smaller listed wearable, a longer nominal wear period and a lower current listed price than Libre 2. Libre 2 is also out of stock at the time of this review. Those facts favour i6 for a new purchase, subject to suitability and compatibility.
This comparison covers Certeza iCan i6 CGM sensor and Abbott FreeStyle Libre 2 CGM sensor. It uses published sensor specifications and the current store listings, rather than a hands-on clinical test.

Why might an existing Libre user still pause?
Changing sensor brands changes the app workflow and the reports you share. If Libre 2 already fits your care plan, ask your clinician how a transition would be managed. Do not let a sensor supply gap force an unplanned switch without a backup monitoring arrangement.
The i6 price advantage should be assessed over the wear period, not only against one Libre 2 box. It offers one more nominal day per session in this comparison. At the same time, a smaller housing is not proof of a better clinical result.
Compare the ongoing sensor budget
At these listed prices, iCan i6 has the lower calculated daily cost. Its 30-day equivalent is PKR 34,000, approximately PKR 4,569.29 less than FreeStyle Libre 2.
Calculation: sensor price ÷ maximum wear days × 30. This is a normalized consumption estimate, not a monthly package offer or checkout total. It excludes delivery, other supplies and sessions that finish early. Whole sensors must be purchased, so cash spending in a particular month can differ.
Which sensor should you shortlist?
i6 is the stronger shortlist here for current availability, listed size and sensor budget. Continuing Libre 2 may make sense for an established compatible setup if a reliable supply can be arranged.
Can I move my existing sensor data into a different app?
Do not assume complete history transfers between manufacturers. Before switching, save the reports your clinic needs and ask how future reports will be shared. Start the new sensor only with its supported app and instructions.
Check compatibility before buying
Confirm the exact phone model, operating system, sensor region and app availability. Ask about supported alerts, report sharing, training and the written sensor-replacement process. If you need a device for a child, pregnancy or another specific clinical situation, have your clinician check the supplied indication rather than relying on a general comparison.
Follow your care plan and device instructions if a reading does not match your symptoms. A buying comparison does not establish which sensor is clinically right for every person.
