How to Use

Priority List

Select Agents and W-Engines from the active banners to add them to your priority list. You can drag and drop items in the list to reorder them (tap and hold on mobile).
The planner strictly follow this order.

Resources

Specify your current available pulls and your expected income. A rough estimate for F2P players is about 100 pulls per month, which is 75 pulls per banner. This assumes you complete everything and includes Residual Signals.
You calculate yours. Income Overview in the Official HoYoLab app can help.

Pity & Guarantee

Enter your current pity count for both Agents and W-Engines, and toggle the Guaranteed checkbox if your last pull was not from the featured banner.
These settings are separate for S-Ranks and A-Ranks.

Safety Floor

Safety floors to change the confidence level of the planner.
This is the primary way to get a good overview of your chances.

• p50 Median: Half the time you'll spend more, half the time less. This is a good baseline luck level.
• p60 Safe: Adds a small buffer over median, this is a realistic default.
• p75 Very safe: You have a 75% chance to achieve your target. You can do it!
• p90 No surprises: Absolutely no way to miss this.
• EV Expected Value: The average cost if you could pull infinite times.

Luck Controls

These adjust the planner's assumption of luck.
This is the secondary way to control the probabilities.
It's fine to just leave this at Realistic.

• Best: Assumes you win every 50/50 and 75/25.
• Realistic: Uses standard probabilities (50% for Agents, 75% for W-Engines).
• Worst: Assumes you lose every 50/50 and 75/25.
