For iPhone & Apple Watch

Train with diabetes. See what every workout does to your glucose.

DiaFitus is a workout and glucose coach in one app. It builds a safe plan around your diabetes, checks your glucose before you move, and shows you what happened afterwards, so exercise stops being guesswork.

What DiaFitus does

Exercise is one of the best things you can do for diabetes. It's also one of the hardest to get right.

Movement lowers glucose, but by how much depends on you, the workout, your medication and your last meal. DiaFitus puts coaching, glucose and food in one place so you can train with confidence.

The problem

Training feels risky

Lows during or after exercise, highs from stress, and not knowing what to eat first make many people avoid exercise altogether, or train and hope for the best.

What we do

One app, one clear loop

A plan built for your diabetes, a glucose check before every workout, guided training, and a chart that shows how your glucose responded, plus a meal scanner and a diary.

Who it's for

Anyone living with diabetes

Type 1, Type 2, prediabetes, gestational diabetes and LADA, from first-time exercisers to people who already lift. No sensor required; connect one if you have it.

How it works

Tell us about you

Diabetes type, medication, health conditions, goals, schedule and where you train. Takes about two minutes.

Check before you move

Enter or sync your glucose. DiaFitus says if it's safe to start, if you need a snack first, or if you should wait.

Train with guidance

Follow your plan with steps, tips, sets, reps and a rest timer on your phone, or start from your Apple Watch.

See what happened

Your glucose before, during and after each workout, plus meals and insulin, on one chart. Learn your own patterns.

Personal plan

A plan that starts with you, not a generic template

Answer a few questions and DiaFitus builds your weekly plan and switches on the right safety checks. Take insulin or a sulfonylurea? It knows lows are a bigger risk and checks more carefully. Have neuropathy or retinopathy? It steers you away from exercises that need extra care.

  • Diabetes type and medication: insulin, sulfonylureas, metformin, GLP-1, SGLT2 or lifestyle only
  • Health conditions: neuropathy, retinopathy, heart, blood pressure, kidney, joints
  • Your life: home, gym or outdoors, 1-7 days a week, 15-60 minutes a session
  • Swap any exercise you don't like, or build your own programs

Safer workouts

A glucose check before every workout

Before you start, DiaFitus asks for your glucose (or reads it from your sensor) and gives plain-language guidance based on your medication: go ahead, have a snack first, or wait and treat a low. During the workout, you track sets, reps, weight and rest in one tap.

  • Pre-workout advice that adapts to your medication and level
  • Hypo support: the 15-15 rule and snack ideas built in
  • Ketone reminder when glucose is high
  • Delayed-low reminder two hours later if you're at risk
  • Workout player with last time's sets, personal bests, notes and live heart rate from Apple Watch

Glucose in context

Finally see what exercise does to your glucose

Your glucose chart shows workouts, meals and insulin as markers, so cause and effect is obvious. Tap any workout to see your glucose from one hour before to four hours after, including the lowest point and a delayed-low warning.

  • Glucose before, during and 60 minutes after your workouts
  • Time in range, average and time low for a day, week or 90 days
  • Estimated A1C (GMI) and average glucose drop per workout
  • Strength progress by muscle group and a weekly 150-minute goal

Charts use your CGM, Apple Health and manual entries. The A1C figure is an estimate, not a lab result.

AI food scanner

Point, scan, know your carbs

Take a photo of your plate or a nutrition label. The AI estimates carbs (excluding fibre), fibre, protein, fat and calories for each food, with a short tip about its effect on blood sugar. You check and adjust every portion before saving, so you stay in control.

  • Meal photos and nutrition labels, or type it in manually
  • Editable portions: change the grams and nutrition rescales
  • Log insulin with the meal and see your glucose response, for example "105 → peak 139 in 2 h"
  • Saved to Apple Health as carbs, calories, protein, fat and fibre

AI estimates can be wrong. Always check them before dosing insulin.

Works with the sensors and apps you already use

No new hardware. Connect your glucose sensor, Apple Health, Apple Watch and Strava, or just log manually.

  • FreeStyle Libre via LibreLinkUp and Dexcom via Dexcom Share, live every 5 minutes while the app is open
  • Apple Health reads glucose (including CGMs that write to Health), steps, activity, weight and heart rate, and saves your workouts, meals and logs
  • Apple Watch app to start and control workouts with live heart rate
  • Strava to post a workout with its muscle map or route
  • Glucose alerts with your own low and high limits

DiaFitus is not affiliated with Abbott, Dexcom, Apple or Strava. Keep the urgent alarms in your CGM app switched on.

Safety first

Built to support your care team, not replace it

DiaFitus gives general fitness and nutrition guidance. It does not diagnose, treat or prevent any condition, and it never tells you how much insulin or medication to take.

  • Talk to your doctor or diabetes team before starting a new exercise program
  • Keep the urgent low/high alarms in your Libre or Dexcom app switched on
  • AI food estimates and glucose charts are aids, not medical measurements
  • In an emergency, call your local emergency number

Private by design

Diabetes data is deeply personal. We collect only what the app needs, we never sell it, we never use it for advertising and we have no tracking SDKs. CGM logins stay in your iPhone's Keychain. You can delete your account and everything in it from inside the app.

Why DiaFitus

What makes it different

Cause and effect, visible

Simple enough to use daily

Streaks that forgive a missed day, 17 badges, personal bests, gentle reminders and a Sunday recap keep you going without pressure.

Phone and wrist

Start workouts on Apple Watch, see live heart rate and have everything saved to Apple Health.

A human coach, optionally

Sign in to receive coach messages, personal programs and short weekly check-ins. You choose whether to share your training profile.

Works offline

All starter content is bundled in the app, so workouts and recipes work in the gym basement or on a trail.
