Frequently Asked Questions

The Bigfoot Unity White Cap replaces the cap that came with your rapid-acting insulin pen. It is designed to help you remember the rapid-acting insulin doses that you take before eating (Mealtime Insulin) and to bring down a high glucose (Correction Insulin).

1. The White Cap shows how long it has been since you took your last dose of rapid-acting insulin from your pen.
2. You can scan your FreeStyle Libre 2 Sensor with your White Cap to view current glucose readings and trends.
3. The White Cap can receive glucose results from the connected blood glucose Meter (Bigfoot Meter).
4. The White Cap will record and send the past 8 hours of glucose information to the App.

See the Bigfoot Unity System User Guide for complete information on using the Caps with the System. You can download the User Guide within your Bigfoot Unity Mobile App, please select Help and Support from “My Settings.”

To use the Bigfoot Unity White Cap, you will begin by pairing the White Cap in the Bigfoot Unity App. You can follow the steps in the App - Set Up Devices - White Cap.

Once paired, the White Cap is designed to help you remember the rapid-acting insulin doses that you take before eating (mealtime insulin) and to bring down a high glucose (correction insulin).

1. Press the button on the White Cap once, to wake it up.
   • You can view the Time Since Last Dose and a reminder to Scan or Check BG.
   • Scan Sensor with the White Cap. Face the Cap to the Sensor. You will feel a vibration and hear a beep.
   • View your Sensor glucose value, trend arrow, and if you are prescribed correction insulin, the suggested correction insulin, if needed.
   • If using the Meter, perform a fingerstick with the Meter. Place the Meter within 12 inches of the White Cap. Turn on White Cap. Meter reading will display on the White Cap along with the suggested correction insulin, if needed.
2. Press the button on the Cap a second time, to view Meal dose options.
   • Meal dose options include: Small, Medium, and Large (based on meal size), Breakfast, Lunch and Dinner (based on meal time), and three specific carbohydrate amounts and amount of rapid-acting insulin.
3. Press the button on the Cap a third time, to view Meal + Correction dose suggestions.
4. Decide the dose. View your meal and what you plan to eat and decide how much insulin to take based on your meal (and the insulin suggested from Meal + Correction).
5. Take insulin
   • Remove the White Cap from the insulin pen.
   • Place an insulin pen needle on the insulin pen.
   • Dial up the dose on your insulin pen.
   • Inject insulin.
   • Remove the needle and dispose according to your local community guidelines for sharps disposal.
6. Place the White Cap back on the insulin pen to record the dose. You will see the timer on the White Cap return to 0 hr 0 min. 

Always check that the insulin name on the Cap matches the name on the insulin pen you intend to use before making a diabetes treatment decision. If you take a dose with the wrong insulin you could take too much or too little insulin, which may result in a severe low or high glucose.  If you suspect that you have taken the wrong insulin, closely monitor your blood glucose and immediately contact your healthcare professional for advice in managing your glucose.

If your last rapid-acting insulin dose logged using the White Cap was taken within the past 3 hours, the White Cap will display ‘Active Insulin’ and will not display a correction dose. This is because the last dose may be still working to bring down your glucose. Taking another insulin dose on top of the previous dose that is working may lead to hypoglycemia.

Keep your White Cap on your rapid-acting insulin pen, unless you are taking insulin.

Scan the Sensor with the White Cap at least every 8 hours to avoid any gaps in Sensor glucose data. You may scan as often as you like!

To charge the Bigfoot Unity White Cap, you will plug it into the charger that was provided in your Bigfoot Unity Training Pack. If your Cap is completely dead (no power), it will take up to 6-hours to fully charge the Cap.

Sensor glucose values, which are based on glucose levels in the interstitial fluid (fluid right below the skin), can be different from blood glucose values, measuring glucose from the capillaries in the blood (fingersticks). This can be especially true during times when your glucose is changing quickly (for example: after eating, after exercising or after taking a dose of insulin).

If your glucose readings and alerts from Bigfoot Unity do not match your symptoms or expectations, perform a fingerstick with your Meter to make diabetes treatment decisions.

Talk to your health care professional if you have questions about how you should use your Sensor glucose information to help manage your diabetes.

No, if using Bigfoot Unity, you can only link to the Bigfoot Unity App and use the White Cap to scan the Sensor.

To communicate the Bigfoot Meter blood glucose reading to the Bigfoot Unity System, you must have your Bigfoot Meter and Bigfoot Unity White Cap within 12 inches of each other.

1. Perform a fingerstick with the Bigfoot Meter.
2. Once the blood glucose value is shown on the Meter, turn on the White Cap by pressing the button one time to display the Time Since Last Dose screen.
3. The blood glucose value will display on the White Cap and in the App.

Tip: Wake up the Bigfoot Meter and the White Cap at the same time for the glucose information to be displayed.

If it has been greater than 10 minutes since performing a fingerstick with the Meter, it will not display the information to the White Cap. You will need to retest your fingerstick with the Meter. 

In order to share your blood glucose values with the Bigfoot Unity System, you must use the Bigfoot Meter that came with the System to have communication across devices and in the Bigfoot Unity App.

There are four alerts on the Bigfoot Unity Diabetes Management System. Alerts will display, sound and vibrate on your App/phone.

1. Very Low Glucose Alert: You will receive this alert when your glucose is less than 55 mg/dL. This is a mandatory alert, you cannot turn it off.
2. Low Glucose Alert: You will receive this alert when your glucose is less than 70 mg/dL.
3. Sensor Unavailable Alert: You will receive this alert when your Sensor is unable to obtain and send a glucose reading or Alert to your App.
4. Long-Acting Dose Alert: You will receive this alert when Bigfoot Unity thinks you may have missed a long-acting insulin dose from your Bigfoot Unity Black Cap.
   1. The pre-set duration time for this alert is 25 hours. You have the option to select the duration time from 24 - 48 hours.
   2. Important Note: Prior to taking your long-acting insulin, check the Time Since Last Dose on your Bigfoot Unity Black Cap to verify if a long-acting dose is needed. You may have received this Alert in error, if your App and Bigfoot Unity Black Cap have not communicated recently. (Remember: Cap before App)

With proper setting, Alerts will display in the App, AND provide a sound AND vibrate on your phone.
