The Best AI Calorie Tracker for Runners in 2026
Runners have a problem most calorie apps ignore: your needs change every day. A rest day might need 2,200 kcal. A 20 km long run pushes the same body to 3,400 kcal. Setting a static daily goal in MyFitnessPal and "logging exercise" doesn't solve it — your goal still shows 2,200 while you stare at a depleted fridge.
What "training-aware" actually means
Vyka reads your workouts from Apple Health the moment they finish. If you ran 12 km this morning and burned 720 kcal, your daily target moves to ~2,920 kcal. Vyka also tells you how to spend those kcal: prioritize carbs to refill glycogen, hit your protein target, don't ignore fat.
Daily plan for a typical training week
- Monday rest: maintenance kcal, normal macros
- Tuesday intervals: +400 kcal, carb-skewed pre and post
- Wednesday easy 10k: +500 kcal
- Thursday lift: +250 kcal, protein push
- Friday rest: maintenance
- Saturday tempo: +450 kcal
- Sunday long run: +900 kcal, carb-heavy day
You don't compute any of this. Vyka does, then shows three rings: calories, protein, training adherence.
Photo logging on race-day morning
Race-morning oatmeal + banana + coffee at 5 a.m., one hand on the spoon. Photograph it. AI scan gives you 480 kcal / 12 g protein / 88 g carbs / 6 g fat in three seconds. Or use voice: "oatmeal with a banana and black coffee."
Weekly AI analysis
Sunday night Vyka summarizes your week: did your fueling match your training load, where did you under-eat, what to adjust for next week. This is the part MyFitnessPal and Cal AI don't do.
Why not just use Strava + a generic calorie app?
You can. You'll spend 10 minutes a day stitching them together. Or your calorie target stays static and you guess. Vyka removes the stitching.
