How do I start a 10 minute timer?

It is already set. Press Begin and the hourglass starts draining for 10 minutes. Nothing to install and no account.

Completely, with no sign-up and no account. Nothing you type ever leaves your device.

10 Minute Timer

Ten minutes is the classic momentum trick. Promise yourself you will stop when the sand runs out. Most people do not stop, because getting started was the barrier, not staying started.

Set for 10 minutes and ready to start. Good for a focused burst, a tidy-up, or a warm-up before a longer block.

Ten minutes as a decision, not a session

Ten minutes is enough to find out whether a task is genuinely hard or merely unfamiliar. Most things that felt impossible turn out to be tedious, and tedious is survivable. Use it as a scouting run rather than an attempt.

Best suited to anyone avoiding one specific thing.

What should I do when the ten minutes are up?

Stop, or keep going, and both are wins. If you stopped, the task is now started and smaller than it was. If you kept going, the timer did its job and you can set a longer one.

SAND. Bottom pile is graded like the top one — no light/shadow split; its colour follows the time of day. Cone lift is what separates the raised pile from the flat bed behind it.

PILE GATHERING. The sand spreads evenly first, then a pile starts small and builds. Start = when the mound begins, Ramp = how much more drain until it is the full solved cone.

Place=1, then drag the sun/moon in the sky — it edits the phase you're viewing (scrub Day time to reach it). Moon shows today's real phase.

Sand light — Mid Day

Edit phase Mid DayExposure 1.00Saturation 1.00Lit light (key) Shadow light (sky)

These edit the selected Time-of-day phase. Mid Day is the anchor (identity).

The Rim light (in Glass optics, locked) auto-scales per phase — strong at night, dim by day — so the hourglass stays the hero.
