Latest release on GitHub

Cobblemon Catch Rate Display is open source. Its newest release on GitHub is v2.12.3, published on Sep 20, 2026.

Fixed

  • Timer Ball, Beast Ball, Moon Ball, and Love Ball now calculate correctly on Cobblemon 1.8.1+, while staying accurate for 1.8.0 and earlier. Cobblemon fixed all four of these in 1.8.1: Timer Ball's formula gained a missing +1 base term, Beast Ball's non-Ultra-Beast penalty (previously a no-op due to commented-out code) now really applies at 0.1×, Moon Ball's gate now checks actual time-of-day instead of a world's total elapsed ticks (previously permanently "open" past the first in-game day), and Love Ball no longer requires a species match just to get the base 2.5× opposite-gender bonus. This mod now detects the running Cobblemon version at runtime and calculates each ball using whichever ruleset is actually loaded, so players on either side of the 1.8.1 boundary see accurate odds.

Description from the author on Modrinth

Cobblemon Catch Rate Display

Wondering whether that Ultra Ball is worth throwing? This shows the catch chance Cobblemon will use before you commit.

In battle, hold a Poké Ball to bring up the HUD. It accounts for the target’s current HP and status, the ball in your hand, turn count, and any special ball rules. Heavy Balls, Timer Balls, Net Balls, and the rest will show what is affecting their odds.

Hold G to compare balls. You’ll see how each one performs against the Pokémon you’re fighting, with the strongest options at the top. Outside battle, point at a wild Pokémon while holding a ball to check it there too.

Use K to hide the HUD. You can move it around the screen or change its colors in config/catchrate-display.json. The mod includes translations for 28 languages.

It runs entirely on your client using data Cobblemon already syncs to you, so servers do not need to install anything.
