About the Author — Steve
Hi, I'm Steve — the founder and main author behind WuWa Tools. I've been playing Wuthering Waves since the global launch in May 2024, and I build every calculator and write every guide on this site around one rule: if a number can't be verified against the game itself, it doesn't go on the site.
Why I built WuWa Tools
The original problem was the pity math. When I tried to plan my first guaranteed 5★, the answers I found were guesses — forum threads arguing from memory, "trust me" videos, spreadsheet screenshots with no formulas visible. Wuthering Waves publishes its actual gacha mechanics in-game, so I wrote a calculator that models the soft-pity curve properly, then kept going: echo scoring, material planning, weapon comparison. The Echo Scorer and Pull Calculator came directly from questions I had on my own account.
How I research
- Played, not scraped. Every build guide is tested on a live account before publishing. If a rotation doesn't hit the numbers the guide promises, the guide gets fixed or removed.
- Cite the source. Banner schedules come from official Kuro Games announcements; game mechanics come from in-game data and patch notes. When reliable sources disagree about a number, the guide says so instead of picking a side.
- Updated per patch. Tier lists and calculators are re-verified within 24 hours of every game update, and the date at the top of each guide reflects the last real check — not a cosmetic edit.
- No fabricated data. No invented drop rates, damage numbers, or banner dates. If something isn't confirmed yet, the guide says "unconfirmed" — even when a confident guess would get more clicks.
Background
- Founder, WuWa Tools (2026–present) — free Wuthering Waves calculators and guides in 7 languages.
- Product & digital transformation background — previously built merchant tools serving over a million small businesses at Alibaba Local Services (2019–2021), and led channel digitalization for over a million retailers at Syngenta Group (2021–2023).
The product background matters less than the playing hours, but it's why the tools exist at all: making complex systems legible is the job I've done for 18 years, and Wuthering Waves' damage math is a complex system.
