LabTimerPhD is a count-up and alarming count-down multi-timer.

Before purchasing, please install LabTimer to see the functionality of LapTimerPhD for free. If you like what you see, please come back and purchase LabTimerPhD!

The look and feel of LabTimerPhD is designed to emulate that of standard lab timers, providing quick access to count-down timers and repeat runs. LabTimerPhD is not just good for the lab, though - it is also convenient for cooking, medication timing, working out, and child timeouts.

LabTimerPhD has the following features:
- Four timers on iPod and iPhone; sixteen timers on iPad
- Individual timers are configurable as count-up or alarming count-down
- Customizable text labels for each timer
- Background notifications (iOS4 and newer)
- Large display and buttons
- Display in Hours : Minutes : Seconds (limit above 1000 hours)
- Hour/minute/second buttons can be held to increment time
- Small icons describing the state of all timers
- Disables iPod sleep, keeping your timer running and visible
- Designed to satisfy the lab needs of my molecular biologist wife

Count-up timers have a lap button, allowing users to display a lap time without pausing the running timer.

Count-down timers each:
- Display the projected finish time
- Alarm for one minute
- Silence all alarms by touching the currently displayed time
- After the alarm, display the time elapsed since finish in red
- Repeat the last count-down by:
-- pressing reset while the timer is paused
-- pressing reset after the timer has finished

LabTimerPhD will schedule notifications for any running alarm timers and the screen can be locked while the timers are running. The alarm also plays over and does not interrupt any playing music. While this will finally let you keep your noise-isolating headphones on during long incubations, please remember to experiment responsibly.

There are many timers and stopwatches on the App Store, but they did not fulfill my (or my wife's) needs. We're now using LabTimerPhD, and we hope you will too.

LabTimerPhD has the same functionality as LabTimer. LabTimerPhD gives a way for those who have used LabTimer to support development of this and other applications. The reviews for LabTimerPhD will direct development for both versions.

Please let me know what you think and how LabTimerPhD can be improved, either via a review or the e-mail address on the website.

Thanks for looking!

Clean and simple and works great


This is definitely a five-star app. It is really easy to use and very versatile. I've had the free version for a couple of years and had to upgrade. It's the least I can do to thank the app makers. This app is so straightforward and efficient I wish they would put their talents to making more apps.

By the way I don't work in a lab. I use this when I'm cooking in the kitchen and grilling and have 4 or 5 things going on at once. It's great to be able to label each timer.

Thank you.

Been using for years


I work in a research lab and have been using LabTimer free version almost every day for years. It works exactly as described and I highly recommend it. I just realized LabTimerPhD was being sold (exactly the same as the free version) and figured I’d go ahead and purchase it since it has been well worth the 3 bucks over the years.

Long time, happy user.


I've been using LabTimer, almost daily, since ~2009 to keep track of gels, PCRs, digests, etc. Simple, dependable, awesome.

I'd never even considered looking for another timer and I only noticed the existence of LabTimerPhD when I went looking for a support email address to suggest a feature (and I purchased it).

Try it and then buy it.
