About SumCal

Our Mission

SumCal exists to solve the #1 problem plaguing calorie tracking apps: forgotten calories.

Research shows that people forget 30-40% of the calories they consume daily—not because they're lazy or dishonest, but because liquid calories and casual snacks genuinely slip the mind. That afternoon bubble tea. The handful of almonds at 3 PM. The cream in your morning coffee.

Traditional calorie trackers failed you. They demanded perfection: log every grape, every milliliter, every bite. That's not realistic. That's why 70% of users abandon tracking apps within 2 weeks.

The Solution: Sneaker Catcher™

We built SumCal around a revolutionary insight from behavioral psychology: the best time to catch forgotten calories is at the end of the day, when you're reflective.

At 8 PM, our Sneaker Catcher™ gently asks: "Any beverages or snacks today?" A quick 30-second visual interface lets you tap what you had. No guilt. No judgment. Just awareness.

Combined with AI-powered meal logging (Claude 3.5 Sonnet, the most accurate food recognition AI of 2025) and personalized Traditional Chinese Medicine wisdom, SumCal finally makes calorie tracking work for real humans.

Why We're Different

  • Behavioral psychology first: We design for how humans actually behave, not how we wish they would.
  • Precision where it matters: Focus accuracy on "calorie bombs" (200+ cal). Estimates are fine for low-calorie items.
  • Non-judgmental: No shame, no scolding. Just education and awareness.
  • Simplicity: Every feature passes the "3-tap test". If it's not simple, we don't ship it.

Our Values

Privacy First

We never sell your data. Ever. Your health information is encrypted, secure, and yours alone.

Evidence-Based

Every feature is backed by research in nutrition science, behavioral psychology, and AI accuracy.

Human-Centered

Technology should serve humans, not the other way around. We prioritize UX over features.

Inclusivity

Health wisdom from diverse traditions (TCM, Ayurveda, Mediterranean) for all body types and goals.

SumCal is powered by:

  • Claude 3.5 Sonnet (Anthropic): AI food recognition with ±12% calorie accuracy
  • React Native + Expo: Native mobile performance on iOS & Android
