Balance at a glance
Calories in vs. out vs. your personalized target — one hero number, with a clear deficit / balanced / surplus read. No spreadsheets, no guessing.

Are you balanced against your goal?
Most trackers dump numbers on you. cal-lowrisk answers one question first — is your day in deficit, balanced, or surplus — then shows the macros behind it.
R&D
cal-lowrisk is in active development. We're building the backend, mobile app, and admin tooling now — this page previews the product and the team, not a live app (yet).
One question,
answered clearly.
cal-lowrisk folds a calorie tracker and a workout tracker into one goal-aware picture — day, week, and month.
Macros that make sense
Protein, carbs, and fat broken out and colour-coded — what made up the day, not just the total.
A target built for you
Your daily goal from your body data (Mifflin–St Jeor → TDEE), adjusted for lose / maintain / gain.
Local-first food
A catalog oriented toward Indonesian meals and household serving sizes — logging feels native, not translated.
Three steps. That's the whole loop.
-
01
Set your goal
Pick lose, maintain, or gain. Add weight, height, age, sex, activity — we do the math.
-
02
Log meals & workouts
A few taps per entry. Catalog foods, custom foods, and workouts with burn estimates.
-
03
See your balance
Daily, weekly, monthly — net calories vs. your target, with the macro story behind it.
Callium
A small team building practical, privacy-respecting health tools. cal-lowrisk is our first product — a modern, enterprise-grade stack built end to end: Go backend, Flutter app, Next.js admin, on PostgreSQL.
- Privacy by design — your logs are yours; admins only ever see aggregates.
- Built in the open, documented as we go.
- Not medical advice — a self-tracking tool, by design.
