Frequently asked questions
Everything you need to know about how GAYA works.
How accurate is GAYA's calorie tracking?
GAYA achieves high accuracy by combining two verification steps: your photo is analyzed to identify every food item, then each ingredient is cross-referenced against 7M+ verified foods spanning FatSecret, Open Food Facts, and USDA databases. Calories are always computed mathematically using the 4-4-9 Atwater rule rather than estimated β so results are internally consistent.
How does the voice coach work?
GAYA's voice coach enables live voice conversations with less than 500ms latency. Before each session, the coach reviews your actual food log, macro breakdown, and progress toward your goals. You can speak with your coach at any time β ask questions, log meals verbally, or request a daily recap.
Is GAYA available on Android?
GAYA is currently available on iOS only.
