What can you do with a 30 second timer?
- Plank, wall sit and hollow holds. Thirty seconds is a common target for core holds; build up from 15 seconds if you need to.
- Static stretches. Holding each stretch for about 30 seconds sits at the top of the 10 to 30 second range that general fitness guidance suggests.
- Interval training. Thirty seconds on, thirty seconds off is a friendly way to start HIIT. The interval timer has a ready-made HIIT 30/30 preset.
- Brushing your teeth. Dentists recommend brushing for two minutes; spend 30 seconds on each quarter of your mouth.
- Hand-washing. Health agencies recommend scrubbing for at least 20 seconds; a 30-second timer covers the scrub and the rinse.
- Elevator pitches. Practice saying who you are and what you do in 30 seconds or less.
How do I use a 30 second timer for brushing teeth?
The American Dental Association recommends brushing twice a day for two minutes. Splitting the mouth into four quarters makes those two minutes easy to get right:
| Round | Area |
|---|---|
| 1 | Upper right, outer and inner surfaces |
| 2 | Upper left |
| 3 | Lower left |
| 4 | Lower right |
Turn on Repeat and the timer chimes every 30 seconds to tell you when to move on; pause it after the fourth chime. Kids in particular find a moving countdown easier to follow than a promise to "keep going a bit longer". Prefer one continuous countdown? Use the 2 minute timer.
Tips for using a 30 second timer
- Choose a gentle sound like Chime for the bathroom, or Digital in a gym.
- Press R to reset between sets without touching the screen with sweaty hands, or tap the big Reset button.
- Use Focus mode for a countdown you can read from a yoga mat.
- Need 45 seconds or a minute? Type
45sor tap 1 min.
How many 30-second rounds fit in a minute?
30 seconds is 0.5 of a minute, so 2 rounds fit in one minute and 120 in an hour.

| Seconds | 30 |
| Minutes | 0.5 |
| Hours | 0.0083 |
| Back to back in one hour | 120 |
