Vertical calculator for niches

Create specialized calculators for overlooked professions (e.g., welders, arborists). Top paid apps show demand for domain-specific math tools.

Why now

Generic calculators dominate stores—professionals pay for tailored utilities.

Who for
Trade professionals
Business model
Paid app + IAPs
Effort
A few weeks

Tradespeople often need quick calculations (material estimates, load limits) but resort to paper or spreadsheets. A calculator app with unit conversions and formulas for one vertical could command premium pricing.

First version: Single niche with 10 key formulas and offline access. Expand via in-app purchases for additional domains.

Risk: Narrow audience limits virality.
