Free, no account

Small tools that
just work.

No sign-in, no ads, no interstitial before the thing you came for. Each one does its job completely and then gets out of the way.

✦ Measure time

Counting down, counting up, or counting the days.

Online timer

Every common countdown length, with an alarm and a visual ring.

Stopwatch

Laps, splits and hundredths, accurate through a sleeping laptop.

Countdown to a date

Days, hours and minutes until anything, shareable as a link.

✦ Protect attention

For one person, or for a room that has to stop together.

Pomodoro timer

Work, break, repeat — with the rounds counted for you.

Shared timer

One countdown a whole room watches, with a pause everybody sees.

✦ Decide things

For when the hard part is choosing rather than timing.

Random picker

Pick a name, split into teams, or settle it with a spin.

Meeting cost calculator

What that hour costs, counting up while it runs.

Priority matrix

Sort what matters from what is merely loud, then keep the result.

✦ The catch

There isn’t one, exactly.

But there is a limit, and it is the same limit on every tool here.

Each of these measures or sorts something and then forgets it. The stopwatch does not know what you timed. The Pomodoro counts four rounds and cannot say what they went into. The matrix sorts your week and has no idea whether you did any of it. That is fine — a tool that does one thing completely is worth more than an app that does six things badly, and these are free for as long as they are useful to you.

EvyOS is the same tools with a memory: goals, projects, tasks, habits and skills, with the sessions logged against the work they belonged to. If the forgetting has never bothered you, you genuinely do not need it.

✦ Questions

The free tools, answered.

Yes. No account, no card, no download and no ads on any of them. Nothing is behind a sign-in and nothing is a trial.
Because it is the honest version of a demo. Each of these does one useful thing completely, and each one stops at the same place: it measures or sorts something and then forgets it. If that limit never bothers you, the tool is yours for free forever. If it does, that is exactly what the app is for.
Yes, all of them, in any mobile browser. The timers and the countdown also ask to keep the screen awake while they run.
Almost nothing. The picker and the calculators keep everything in the page and lose it when you close the tab. The priority matrix saves in your own browser and never leaves your device. Only the shared timer keeps anything on a server, and that is a length, an optional label and no identity at all.

Use them forever, free.
Or keep what they measure.

One system for the goals, projects, tasks, habits and skills the tools are in service of.
