Time Precision - Every timezone you care about. One glance. Zero clutter.

Time Precision docks a slim rail to the edge of your Windows desktop and shows every timezone you've pinned, always visible, never in the way. It expands on hover and tucks back out of sight otherwise — no browser tab or phone needed. 233 cities across 11 languages, interface and label language set independently. 9 built-in themes, drag-to-reorder zones, and pinned apps for quick launch. Free, no account required.

SublimeKeys - Sell your desktop app. We handle the license keys.

Most license key tools are either roll-your-own scripts (fragile, no offline story) or enterprise DRM (overkill for a solo dev). SublimeKeys sits in between: one tiny API to generate, activate, and verify keys — device-locked, revocable, with offline verification lasting 7 days without a network call. Ships with Python and Node/Electron SDKs, a free tier, and a dashboard live in 12 languages. Already the license server behind ReelNox Studio and BackDrop_.

BackDrop_ - Ghost video overlay — watch anything while you work

I kept pausing the same anime episode to get back to work. So I built BackDrop_. It plays any local video (MP4, MKV, AVI, MOV, TS) as a transparent overlay on your full Windows desktop. Opacity from 0–100%, mouse clicks and keyboard pass through to whatever's underneath. No cloud. No account. Files stay on your drive. One-time payment. Works for anime while coding, news overlays for traders, or ambient video while studying.
