What makes HabitHelm different
A daily target that fits the day you had
Training days count
After a long ride you need more fuel than on a rest day. HabitHelm adds part of your training energy to your calorie target and raises carbs on hard days.
Hydration by sweat rate
Your fluid target rises with training and heat. For outdoor sessions from Strava, HabitHelm factors in the weather, and your own sweat tests make the advice personal.
Numbers you can follow
No black box: the diary shows exactly how today’s target was built. Every assumption can be adjusted or replaced with targets of your own.
How it works
Three steps to a target that fits
No spreadsheets, no formulas. HabitHelm does the maths, you eat and train.
Set your profile and goal
Height, weight, age and what you’re after: losing fat, building muscle, maintaining or cycling performance. That gives you a baseline.
Connect Strava or Withings
Workouts and activity flow in automatically. Without a connection HabitHelm works just the same, only without the training credit.
Log your food
Search or scan a barcode, pick a portion, done. The diary shows what’s left in real time, including protein, carbs and water.
A diary that keeps up with you
Find foods by searching Open Food Facts or scan a barcode with your phone’s camera, right in the browser. Recipes, water and custom entries go into the same diary.
- Barcode scanner in the browser, no app to install
- Nutri-Score, NOVA group and allergens on product pages
- 3 meals or 7 time slots, to match how you eat
More fuel on training days
Your baseline comes from the Mifflin-St Jeor equation and your goal. Activity from Strava or Withings is added conservatively: 40 to 60 percent of the recorded energy, capped at 500 kcal a day.
- Carbs in five steps from 3 to 10 g per kg of body weight
- Protein at 1.6 to 1.8 g per kg, depending on your goal
- Everything adjustable, or replace it with fixed targets
Micronutrients at a glance
HabitHelm compares your intake with the reference values of the German Nutrition Society (DGE), matched to your age and sex. You’ll see whether iron, magnesium or vitamin D tend to run low.
Who it’s for

Frequently asked questions
Is HabitHelm free?
Yes. During early access every feature is free and no payment details are needed. The diary, barcode scanner, training-based targets and integrations stay in the free plan afterwards too. Details are on the pricing page.
Do I need a sports watch?
No. Without a connection HabitHelm works from your profile and goal. With Strava or Withings, your training energy is added automatically.
Does HabitHelm work with Garmin?
Yes, through Strava: if Garmin Connect uploads your activities to Strava, HabitHelm picks them up from there. Garmin workouts can’t be imported directly yet. More on the Garmin page.
Is there an app?
HabitHelm runs as a web app in the browser on phones, tablets and computers, and the barcode scanner uses your phone’s camera. An iPhone app is in the works.
