Reviews from the App Store
I'm a Type 1 Diabetic and I was using the ACCU-CHECK guide and app for my bolus advice. Their app stopped working. I needed to convert my glucose to mmol/L. I found Mila's free blood sugar converter. It is perfect.
I really like your app. I use it to convert my glucose reading into an A1C reading. This helps me monitor my daily sugar levels.
You can put a value in any of the measurement systems and it will instantly convert it to all the other systems, and it will give you a red to green bar graph showing whether you are within the optimal range. Simple, yet perfect.
About Mila's Blood Sugar Converter
Lab results in mg/dL but your doctor quotes mmol/L? Need to translate an HbA1c percentage into the IFCC mmol/mol standard? Mila's Blood Sugar Converter converts between 8 glucose-related units in real time - with a color-coded range indicator so you can see where a value falls without memorizing thresholds. From the developer of Unit Converter: Mila's Tools (Apple Staff Pick, 4.8★ from 1,300+ reviews).
Units and standards
- mg/dL and mmol/L - the two most common blood glucose scales
- HbA1c (%) and mmol/mol (IFCC) - long-term glucose monitoring standards
- μmol/L, mg/L, μg/mL, and GMI (%) for specialized reports and research contexts
Visual range indicator
A color-coded slider shows whether a reading falls in low, normal, pre-diabetic, or diabetic ranges - at a glance. Thresholds are customizable to match what your healthcare provider recommends, with a reset to defaults anytime.
HbA1c conversion
Switch between NGSP/DCCT percentage and IFCC mmol/mol without doing the non-linear math yourself. Useful when comparing lab reports, research papers, or international medical records that use different HbA1c conventions.
