A build optimizer and companion app for gacha-RPGs. Scan your gear, calculate damage, and find your best loadout — for Wuthering Waves and Genshin Impact, with more games on the way.
FrequencyManager is an independent fan-made project and is not affiliated with, endorsed by, or sponsored by Kuro Games, HoYoverse, or any other game developer/publisher. Wuthering Waves, Genshin Impact, and all related assets are trademarks of their respective owners.
FrequencyManager is a free desktop companion app for gacha-RPG players who want to get the most out of their characters' builds. Instead of manually theorycrafting stats in a spreadsheet, you tell the app what you own (characters, weapons, gear) and what you're trying to maximize, and it does the math — including searching through every gear combination you own to find the best one.
The app itself ships with no game data built in — Wuthering Waves (echoes) and Genshin Impact (artifacts) are official downloadable game packages, installed the same way any community-made game is (see Installing a game below). Every installed game shares the same calculator, optimizer, and inventory tools — switch between them any time from Settings.
Grab the latest installer from the Releases page:
- Download
FrequencyManager-Setup-<version>.exe. - Run it — no admin rights required, per-user install.
- Launch FrequencyManager from the Desktop or Start Menu shortcut.
- On first launch you'll see a "No game installed yet" screen — download a game package (Wuthering Waves and/or Genshin Impact, also on the Releases page) and drop it into the folder the app shows you, then restart. See Installing a game below for the full steps.
The app checks for new versions automatically and will prompt you to update when one is available. Windows only for now.

| Screen | What it's for |
|---|---|
| Dashboard | A quick overview of your build workspace — recent calculations and scans at a glance. |
| Calculator | Pick a character, set what you want to maximize (or hit a minimum threshold for), and either see live stats for your currently-equipped gear or run the Optimizer to search every combination of gear you own for the best build. Supports crit modes, elemental reactions (Genshin), a Set Bonus picker, and Party Setup for team-wide buffs. |
| Scanner | Point your hotkey at an in-game gear screen and FrequencyManager reads the stats off the screenshot (OCR) and adds it to your inventory — no manual typing. You can also scan a previously saved screenshot, or batch-import several at once. Currently supported: Wuthering Waves echoes only (see below). |
| Inventory | Manage everything you own: characters, weapons, and gear. Add, edit, equip, and unequip pieces; filter and sort your gear by stat, set, rarity, or cost; get warned before double-equipping a piece another character is already using. |
| Rotation | Build and save a damage rotation — a sequence of skills/attacks — against your actual party, to see total damage over a fight instead of just a single hit. |
| Settings | Switch the active game, tune calculator/optimizer behavior (like how many CPU threads the optimizer uses), configure the scan hotkey, manage app/game updates, back up or clear your data, and toggle individual feature modules on or off. |
OCR scanning currently supports Wuthering Waves echoes only (Genshin artifacts and any other game/gear type aren't wired up yet — add them to your inventory manually via Inventory → Add). To get a clean scan, line up the in-game Echo screen like this before pressing the scan hotkey:
Character → Echo → select a set → click into an echo → Scan
That's the individual echo's detail view — name, cost, main stat, and sub-stats all visible on one screen, which is what the scanner reads.
Requires the game running fullscreen at 1920×1080. The scanner crops fixed regions of the screen calibrated against that resolution — a different resolution, windowed mode, or a different display scale will crop the wrong area and produce a bad or empty scan.
Game data (character kits, weapons, sets) is hand-curated and cross-checked against multiple community sources, not scraped automatically — coverage and accuracy vary by game as that work continues:
- Wuthering Waves — ~95% accurate (full-roster re-audit against 2+ independent sources completed 2026-07-17).
- Genshin Impact — still in progress.
- OCR scan support — unchanged, Wuthering Waves echoes only (see above).

FrequencyManager ships with no game data built in — every game, including the official Wuthering Waves and Genshin Impact packages, is installed the same way:
- Download a game package (a
.zip) from the Releases page — official packages are published there, and anyone can package and share their own. - Extract it into:
(the app creates this folder automatically; if nothing is installed yet, it shows a "No game installed yet" screen pointing here).
%APPDATA%\frequency-manager\game-modules\ - Restart FrequencyManager — the game now appears in Settings → Game.
Once you have two or more games installed, switching between them from Settings → Game takes effect immediately, no restart needed. Your data for each game (characters, gear, loadouts, rotations) is kept separate.
See docs/GAME_MODULES.md for the full format guide, including how to author your own game package.
FrequencyManager checks for updates automatically on launch:
- App updates download and install in the background; you'll get a prompt to restart when one is ready.
- Game data updates (new characters, weapons, balance changes) are checked independently, so the app itself doesn't need a new release just to catch up with a game patch.
You can also trigger a manual check any time from Settings → Updates.
Per-game character/roster data progress and what's planned next now live in ROADMAP.md — short version: Wuthering Waves' full roster just went through a fresh accuracy re-audit (~95%), Genshin Impact is getting the same treatment next, and Rotation Builder is still being refined as a rotation-testing tool.

This is my first public project as a junior developer, built and maintained in my spare time. If you run into bugs, rough edges, or have suggestions, please open an issue — feedback is genuinely welcome and helps me improve both the app and myself as a developer.
