Utility Tools
5 toolsEveryday converters and calculators for students, writers and households.
The small calculations that interrupt a day and are not worth an app: how old someone is, what a percentage of something comes to, how long a piece of writing takes to read, what a measurement is in other units.
All of them run instantly and none of them ask for anything. The word counter and unit converter in particular keep working with the network off, once the page has loaded.

How these tools work
Every one of these 5 tools runs entirely in your browser. There is no account to create, no file to upload and no daily limit, because the work happens on your own device rather than on a server — which also means there is nothing for us to log, cache or leak. Most of them keep working with the network off once the page has loaded.
