Ping-Pong App Switcher Lock

Add a lock to ⌘-Tab so blind switching while coding stops getting hijacked

Problem

Heavy agent users keep one eye on the coding agent and the other on docs in the browser; the highest-frequency gesture is a blind ⌘-Tab tap. But chat apps like WeChat keep jumping into the switch chain and breaking focus. These pains are small, unglamorous, and happen daily.

Solution

A macOS menu-bar utility that pins frequently paired windows into a controlled switching ring; ping-pong mode bounces only between two targets and temporarily excludes other apps from the ⌘-Tab sequence, with one-key pause, hotkey summon, and auto-profile switching based on the focused app.

Users

Indie developers using AI coding agents, solo engineers running multi-platform products, and knowledge workers who need long deep-focus stretches

MVP

Two-window ping-pong switch lock; configurable excluded-app list; menu-bar toggle and global hotkey; switch history with one-click jump-back

Revenue

One-time purchase after a 14-day trial, priced at $10–20; multi-seat licenses for small teams

Why now

Coding agents keep engineers staring at terminals, sharply raising window-switch frequency; system-level keyboard tools are well-understood and one person can ship a stable build in weeks.
