Pull & Investment Advisor
Tick what you own and at what amp tier. The advisor tells you who to pull, who to amp, and which wingman to grab for your goal.
Every S-tier pilot performs well once amplified to their breakpoints — differences exist but are often small. Recommendations weigh crowdsourced mode scores (0-10) against your goal, roster, and active banners. They're opinionated and not a final verdict; a pilot you enjoy investing in will outperform a "better" one you don't.

How to get battle logs (Android only)
Battle logs are currently only available on Android. They are stored at /sdcard/Android/data/com.vizta.wefly/files/dragon2019/Flog/.
Due to Android scoped storage restrictions (Android 11+), regular apps and browsers cannot access this path. There are a few ways to extract the files:
Option 1: ADB (recommended)
Use ADB (Android Debug Bridge) over USB or WiFi to pull the files to your computer:
adb pull /sdcard/Android/data/com.vizta.wefly/files/dragon2019/Flog/ ./logs/
See the ADB setup guide for instructions on enabling ADB and connecting to your device.
Option 2: Shizuku + file manager (no PC needed)
Shizuku lets normal apps access restricted paths using ADB privileges — no root required. Pair it with a compatible file manager like Solid Explorer, FV File Manager, MiXplorer, X-Plore, or Total Commander to browse and copy the files directly on your phone. See the full list of Shizuku-compatible file managers.
Option 3: Rooted device
If your device is rooted, any root-enabled file manager (e.g. Solid Explorer with root access) can browse /sdcard/Android/data/ directly.
Once you have the .battlelog files, drag & drop them below to analyze. Files are processed entirely in your browser — nothing is uploaded or sent anywhere.
