What's the best app to track HbA1c over time?

For tracking HbA1c from standard lab results, Bevita reads your lab PDFs, tracks HbA1c across every test, and calculates related markers like HOMA-IR from fasting insulin and glucose. Dedicated diabetes apps (like mySugr) focus on daily fingerstick glucose logging, while CGM apps track continuous glucose. The best choice depends on whether you're tracking lab values, daily readings, or a continuous sensor.

Can an app calculate my insulin resistance from blood sugar?

Some can. HOMA-IR — the practical insulin-resistance score — is calculated from fasting glucose and fasting insulin. Bevita computes it automatically when both values are in your labs, which most general glucose-logging apps don't do. This catches early insulin resistance that a normal HbA1c can hide.

Do I need a continuous glucose monitor (CGM) to track blood sugar?

Not necessarily. A CGM gives real-time, minute-by-minute data and is powerful for understanding meal responses, but it's not required. For most people tracking metabolic health, lab-based HbA1c and fasting glucose/insulin over time — which an app can trend for you — give a solid, lower-cost picture.

Best Apps to Track HbA1c and Blood Sugar (2026)

Blood sugar is one of the most important things to track for long-term health — about 96 million US adults have prediabetes and most don’t know it (CDC). But “tracking blood sugar” means different things: daily fingersticks, a continuous sensor, or the lab markers (HbA1c, fasting glucose, fasting insulin) that show the bigger trend. The right app depends on which you’re doing.

The three kinds of blood-sugar apps

Lab-trackers — read your blood test results (HbA1c, glucose, insulin) and trend them over time.
Glucose loggers — record daily fingerstick readings, mainly for people with diabetes.
CGM apps — pair with a continuous glucose monitor for real-time data.

Most people watching metabolic health want the first — the lab-level trend — and that’s where results most often get lost in scattered PDFs.

The best options

Bevita — best for lab-level tracking and early detection

Reads your lab PDFs, tracks HbA1c across every test, and calculates HOMA-IR from fasting insulin and glucose — catching early insulin resistance that a normal HbA1c can hide. Ties results to symptoms and exports a doctor-ready PDF. Free to start, any lab.

mySugr — best for daily glucose logging

A well-designed logbook for people with diabetes doing daily fingersticks — bolus calculator, reminders, reports. Focused on daily management rather than lab-marker trends.

CGM apps (e.g. sensor companion apps) — best for real-time data

If you wear a continuous glucose monitor, these show minute-by-minute glucose and meal responses. Powerful, but sensor-dependent and more than many people need.

General health apps — limited for blood sugar

Apple Health and similar can store a glucose value but don’t calculate derived markers or flag early insulin resistance. (More on that in Apple Health vs a dedicated lab tracker.)

How to choose

Your situation	Best fit
Watching metabolic health / prediabetes	Bevita (lab trends + HOMA-IR)
Managing diabetes with daily fingersticks	mySugr
Using a continuous glucose monitor	Your CGM’s companion app
Want labs + everything in one record	Bevita

What this looks like in Bevita

Bevita's Overall picture screen showing HbA1c 5.5% alongside a calculated HOMA-IR of 2.02 and an early insulin resistance flag

Here’s what a lab-level tracker adds. On this Bevita screen, HbA1c reads a normal 5.5% — but Bevita also calculates HOMA-IR (2.02) from fasting insulin and glucose, flagging early insulin resistance the HbA1c alone would miss. That’s the difference between logging a number and understanding it: the app surfaces the metabolic strain behind a “normal” result and tracks it over time.

The bottom line

Tracking metabolic health / prediabetes? A lab-tracker like Bevita gives you the HbA1c trend plus the insulin picture behind it.
Managing diabetes daily? A glucose logger like mySugr fits the day-to-day.
Want the deepest real-time view? A CGM and its app — if you want the detail and cost.
