If this sounds like your week
The stack matters the moment the timer is always running.
“non Electron focus apps for PC” often leads to Electron by default, which is a lot of process overhead for a countdown. TimeFence is local-first, zero telemetry, and built in Rust with Tauri so the HUD does not feel like a second browser living in your task manager. The overlay path is about performance, not about collecting usage graphs.
Where tooling usually breaks
A cloud sign-in to tell time is a design failure dressed as a business model.
The honest reason people search “non Electron focus apps for PC” is that most “apps” are distribution stacks pretending to be tools. A Windows overlay timer should be small, local, and auditable. That is the bar TimeFence is built for: Rust + Tauri, not a second Chromium install with a “productivity” skin.

Telemetry: off
Account required: no (it's a local Windows app)
Runtime: Tauri (native shell) + Rust
Job: a visible HUD, not a growth funnel
