Food logging that feels like texting
TrueCal uses ChatGPT to understand what you ate, estimate portions, and calculate nutrition instantly. Less friction means you actually stay consistent.
The problem with traditional trackers
Searching databases, scanning barcodes, and guessing portions leads to burnout. When logging feels like a chore, consistency drops and results stall.

Use normal language, typos, or quick voice notes. TrueCal understands the intent.
AI expands the context
TrueCal matches ingredients, typical portions, and cooking methods automatically.
Review and refine
Make quick edits if needed. TrueCal keeps the nutrition math updated.

Why it actually works
