Fizz pulls data directly. You don't type anything in. It syncs, analyses, and surfaces what matters.
Fizz correlated 6 weeks of Whoop recovery data with supplement compliance logs. On days I took Mg Threonate 2 hours before bed, RHR averaged 45 bpm. Without it: 52 bpm. Correlation coefficient: 0.87. I would never have connected those two datasets manually. Fizz cross-referenced them automatically.
After ingesting 35 days of daily thought entries, Fizz ran /emerge and surfaced a repeating pattern. Days 1-5: deep focus. Days 6-9: social energy spike. Days 10-12: creative peak. Days 13-14: withdrawal. It now tells me what day I’m on and recommends what type of work to schedule. I stopped fighting the cycle and started using it.
Fizz ingested 4,392 bank transactions across 7 years from NatWest. The headline: £239k in, £228k out. 4.8% savings rate. Income has been spiking since 2025, but spending tracks it almost 1:1. The earning power is there. The retention isn’t. That single insight reframed my entire financial strategy. No budgeting app told me that. Fizz did, from raw transaction data.
“I built Fizz because no product does what I need. I track my macros, sleep stages, resting heart rate, every minute of work, 47 people in my network, supplement timing, testosterone protocol, and 7 years of bank transactions. Before Fizz, that data lived in 6 different apps that never talked to each other. Now it's one system. And it talks back.”
