Best Glucose Tracking Apps in 2026: With or Without a CGM
If you take a GLP-1, live with type 1, or manage type 2, the glucose app you pick will see more of your life than most. Here is the honest comparison, including which apps assume you own a specific CGM and which work regardless.
The short story
There are two camps. Dexcom and Libre own the CGM space and their companion apps assume you own their sensor; everyone else either integrates via Health Connect or asks you to type numbers. If you want glucose tracking that also knows what medications you take and connects to the CGM you already have, MedRemind is the pick. If you only want the official reader for your specific sensor, Dexcom Clarity or LibreLink are the defaults.
At a glance
| App | CGM ingestion | Manual glucometer | Medication context | Free tier useful? |
|---|---|---|---|---|
| MedRemind | Via Health Connect / HealthKit | Yes (BLE or manual) | Yes, meds on same timeline | Yes, no cap |
| Dexcom Clarity | Native (Dexcom only) | No | Light | Yes, sensor-locked |
| Abbott LibreLink | Native (Libre only) | No | Light | Yes, sensor-locked |
| mySugr | Limited CGM | Yes | Medium | Yes, export paywalled |
| Glooko | Multi-brand CGM | Yes | Medium | Yes, advanced reports paid |
| Apple Health | Via manufacturer apps | Yes | None | Yes |
| Samsung Health | Galaxy Watch glucose limited | Partial | None | Yes |
1. MedRemind
Glucose is only useful when you can match it to what you took and when. MedRemind reads CGM values through Health Connect on Android and HealthKit on iOS, accepts manual entries from any Bluetooth glucometer or a large keypad, and lines them up against your medication times. The export your endocrinologist sees is a clinical CSV with time, value, unit, source, and dose all on one row.
Strengths. Medication context, no sensor lock-in, works with any CGM whose official app syncs to Health Connect or HealthKit, no reading cap in the free tier.
Limits. For raw CGM-specific features (sensor calibration tools, Dexcom Share alerts), you still use the sensor's official app alongside MedRemind.
2. Dexcom Clarity
If you wear a Dexcom sensor, this is the app that reads it and the app your endocrinologist pulls reports from. It does CGM well and nothing else. Zero medication context.
3. Abbott LibreLink
Same story for Libre users. Tight integration with Libre sensors, limited beyond that.
4. mySugr
The friendliest diabetes-specific logging app. Imports from some CGMs. The "Pro" report and physician-friendly PDF sit behind the premium tier.
5. Glooko
Clinician-facing, multi-device tolerant. Accepts CGM data from several brands and supports pump data. If your clinic already uses Glooko, sticking with it makes sense. If not, the app is overkill for a casual tracker.
6. Apple Health / Samsung Health
Passive buckets. Good for aggregate viewing if many apps write into them, but none of them know what medication you took at 8 AM.
GLP-1, Ozempic, Wegovy: which app helps most?
People on GLP-1 medications are the fastest-growing subset of glucose trackers. You do not need a CGM to benefit, but if you have one, the week-of-injection pattern becomes visible in the data. MedRemind is the only app in the comparison that tracks the weekly injection, the injection site rotation, and the glucose trend on the same timeline. See the injection rotation guide for the companion workflow.
Choosing fast
- Wearing a Dexcom or Libre and only want CGM? Use the official app.
- On any oral or injectable diabetes medication and want to see the whole picture? Use MedRemind alongside the sensor app.
- On a GLP-1 without a CGM? Use MedRemind with a Bluetooth glucometer or manual entries.
- Your clinic runs Glooko? Keep Glooko for the clinic and MedRemind for your daily use.
Frequently asked questions
Does MedRemind replace my CGM app?
No. The sensor manufacturer's app handles sensor-specific functions like starting a new sensor and Dexcom Share alerts. MedRemind reads the resulting data through Health Connect or HealthKit and combines it with your medications.
Can I log glucose without a sensor or Bluetooth device?
Yes. The large keypad is built for quick manual entries.
Will my numbers appear in Apple Health or Samsung Health?
Yes, through HealthKit and Health Connect respectively, if you grant the permission.
Is the CSV export free?
Yes. Export is a core feature, not a paid one.
Where MedRemind beats the category
Safety features that should never sit behind a paywall are free here, and the tools that usually require a separate specialty app are built in.
Scan instead of typing. The camera reads the bottle label or the box barcode and fills the form. Medisafe, MyTherapy, Pillo, Dosecast, Round Health and MedTimer do not ship this.
Drug interactions, free and offline. Six severity levels, runs on the device in airplane mode. Medisafe paywalls its version. MyTherapy, Pillo, Dosecast and MedTimer do not have one at all.
Offline drug encyclopedia. The full FDA label and Spain's CIMA registry ship inside the app. No competing reminder app bundles a drug reference; the rest fetch from the network or skip it.
GLP-1 and insulin injection rotation plus the full vitals stack. A body-map tracks each injection site. Glucose (manual or Bluetooth meter), blood pressure, weight, SpO2, heart rate and temperature all live on the same timeline as your medications. Pair a Bluetooth glucometer or cuff, sync through Health Connect, or type the values on a large clear keyboard. Clinical CSV export for the visit. Specialty apps like Shotsy do rotation alone. Nobody else in the reminder category brings vitals, CGM and dosing into one screen.
Three-level caregiver access. View, log or edit, with QR and 6-digit invite codes, SMS consent, and separate profiles for dependents and pets. Medisafe has a caregiver mode without this granularity. The others barely have a caregiver flow at all.
Lock-screen privacy mode. Two notification channels hide medication names until the phone is unlocked. Nobody else in the category has this.
A free tier that is actually free. No two-medication cap (Medisafe), no paywall on interaction warnings (Medisafe), no ads in the experience (Mango Health), no cloud-sync fee (Dosecast).
