Inventory Timer
by Br1ef
Inventory Timer is a Fabric client-side mod that tracks how long a player takes to swap items, pop totems and drink potions during combat.
What it does
The mod times inventory actions so a player can see how quickly a totem, a potion or a weapon swap is completed. Its author describes it as built for one purpose: sharpening the timing of totem swaps and potion use under pressure, where a delay of a few milliseconds decides the outcome. Only the client needs it, and servers run without it, which keeps it a personal training tool rather than a gameplay change.
The mod targets the Fabric loader and works on Minecraft 1.21 and 1.21.1, with 1.0.0 for 1.21.1 as the latest file. Files were first published on 2026-03-09 and last updated on 2026-03-10. Inventory Timer is not open source and is released under All rights reserved, so its code is not available for reuse.
Key features
Inventory action timing
Measures how long each inventory action takes, so a slow swap or potion can be compared against the player's own pace.
Totem pop practice
Repeated totem swaps can be timed to build a steady reaction and reduce hesitation in fights.
Potion speed tracking
Tracks how fast potions are drunk from the hotbar, helping a player see where the delay comes from.
Focused training screen
Keeps the display on the timing itself rather than the wider game, so practice stays on a single goal.

Use cases
PvP reaction practice
A player trains totem and potion swaps in a low-pressure setting before joining a combat server.
Spotting late swaps
Timings show whether a late swap or late potion comes from the inventory action or from the reaction that starts it.
Who it’s for: Players who want to improve their inventory speed in combat, mainly in PvP, and who play on Fabric with the mod installed on their own client.

What the author says
InventoryTimer is built for one purpose: turning hesitation into instinct. It creates a focused environment where every milisecond matters, helping you sharpen totem timing and potion speed under pressure. Most players don’t lose because of aim—they lose because they’re late. Late to swap. Late to pot. Late to react.
