Chimelark: live timers for Google Slides™

Type <<5:00->> on a slide, start the slideshow, and it becomes a live countdown that rings at zero. Decks that already use these tags keep working.

What it does

• Countdowns, stopwatches, clocks and dates from tags like <<5:00->>, <<0:00+>>, <<time>> and <<longdate>>.
• Go to the next slide at zero with <<3:00-+>>, keep a timer running across slides with ~, start paused with $.
• Tags in the speaker notes: students see the timer in a corner, never the tag.
• Keys: Y pauses and resumes, R resets. Extended time runs every countdown 1.25×, 1.5× or 2× as long, for testing accommodations.
• Pro: several timers on one slide, fonts, colors and highlights, more sounds or your own, progress bars and pomodoro cycles.

How it works

1. Add Chimelark to Chrome, Edge or Firefox.
2. In Google Slides, type a tag on a slide or in its speaker notes.
3. Click Slideshow. The tag turns into a timer.

The free Chimelark add-on for Google Slides can insert tags for you and check every tag in a deck.

Free and Pro

Free covers one running timer per slide, unlimited clocks and dates, every tag, the keys and extended time, with no time limit. Chimelark Pro is $9, paid once. There's no subscription.

Private by design

Chimelark runs only on Google Slides pages. It doesn't ask for your browsing history, your tabs, your email address or a sign-in, and it has no servers: your slides never leave your computer. The only outside request is checking a Pro license key with Gumroad, and only after you activate one. Read the privacy policy and terms.
