Tools built for
Developers.
UntangleTools is a growing suite of free, precision-grade tools designed to remove friction from your workflow — whether you're converting units, picking fonts, visualising algorithms or tracking exchange rates.
One home for tools
you actually need
We're not building a single app. We're building a platform where every tool is first-class, free, and obsessively well-designed.
Unit Converter
Instant, SI-standard conversion across length, mass, temperature, volume, area and time — with more categories shipping soon.
Currency Converter
Live exchange rates for every global currency and cryptocurrency, updated in real time with historical trend charts.
Font Preview Studio
See any Google Font inside realistic UI templates — navbar, card, hero, body copy — before you ship a single line of CSS.
The best tool is the one that gets out of your way.
We started UntangleTools because every existing tool was either cluttered with ads, hidden behind a paywall, or just ugly. We think that's wrong. Utility software should be a joy to use.
Our principles
Precision First
Every tool we ship is grounded in authoritative standards — SI, BIPM, NIST, ISO. Correctness is non-negotiable.
Zero Friction
No sign-ups. No paywalls. No ads. Open the page, get the answer, move on. Your time is the product we respect.
Design as Function
Beautiful interfaces reduce cognitive load. We believe clarity and aesthetics are the same thing.
Universal Access
Tools that only work for some people don't work at all. Everything we build is free, global and accessible.
