Can you vibecode this?

Yes

Two native apps (Swift for Mac, Windows) with display color filtering and backlight control — all pure code, no licences, no catalogue, no human delivery. The core loop ships; multi-monitor and DDC/CI polish adds time but nothing stops a first paying customer.

Why it works

Value proposition
Eliminates blue light and PWM flicker that other filters leave behind.
Problem

Audience
Mac and Windows users sensitive to bright or flickering screens, including night workers.
Business model
One-time $39 payment for up to 3 computers, lifetime updates, custom team pricing for 5 or more seats.

Why people pay Tap Zap

Tap Zap has paying customers, published spectrometer measurements and a named refund and affiliate program already in place. A fresh copy starts with none of that trust or track record.

Product complexity
Low
Two sliders, three presets and a backlight-lock toggle are standard native app controls.
Data
Low
No outside data or content is needed; the product works entirely on the local display.
Integrations & infrastructure
Low
License validation and payment are handled through standard third-party APIs.
Human operations
Low
A solo founder runs the business with no staff beyond priority email support for teams.
Regulation / hardware
Low
Screen-filter software carries no licences, approvals or compliance requirements.
