Free Online Tools

Free Online Tools brings the freeonlinetools.au toolkit to Android in a faster, app-first experience. Browse 100+ free calculators, converters, and utilities from a native home screen, then open any tool in-app without jumping out to a separate browser.

WHAT YOU GET
A practical everyday toolkit for home, work, study, and projects. Search the full catalogue, star favourites, and jump straight back into recent tools. Categories are organised so you can find the right utility quickly instead of digging through bookmarks.

EVERYDAY CALCULATORS
Loan and mortgage helpers, percentage and tip style maths, unit-friendly everyday numbers, and other common calculators you reach for when a quick answer matters. Useful before appointments, purchases, renovations, and planning conversations.

MATHS AND NUMBERS
Mathematical calculators for students, tutors, and anyone who needs clean, focused number tools without signing up or installing a separate app for each job.

ENGINEERING AND TECHNICAL
Electrical and engineering utilities for trades, students, and DIY technical work. Keep reference-style calculators close when you are on site, at a desk, or checking figures on the go.

CONVERTERS: IMAGE, AUDIO, AND MORE
Convert and transform common files and values with image and audio utilities, plus other conversion tools from the freeonlinetools.au collection. Open the tool you need, run the job, and move on.

DEVELOPER AND PRODUCTIVITY UTILITIES
Handy developer-oriented helpers and general productivity utilities for formatting, checking, converting, and everyday technical tasks. Built for quick use, not account-heavy workflows.

GAMING HELPERS
Gaming tools and helpers when you want a simple utility alongside play, theorycrafting, or setup checks, without turning the whole app into a game store.

KIDS AND FAMILY
Family-friendly tools for shared devices and household use. Practical utilities parents, carers, and older kids can open quickly for school, home, and everyday questions.

OUTDOORS, NATURE, AND MISCELLANEOUS
Outdoor and nature helpers plus a broad miscellaneous set for the odd jobs that do not fit a neat category. If you have used freeonlinetools.au on the web, the same toolkit spirit is here in a mobile-friendly shell.

BUILT FOR MOBILE USE
• Native home screen with search, categories, favourites, and recents

WHO IT IS FOR
Home users, students, trades and engineering learners, developers, parents, and anyone who wants a pocket toolkit of calculators and converters without installing dozens of single-purpose apps.
