Would be Great for Time Courses If the Timers Didn’t Stop When the Lock Screen Engages


The concept of multiple programmable countdown timers is a great idea for Time Course experiments and is really handy to have. However there is a pretty serious bug in this app. When the iPhone goes into lock mode, where you need to enter your passcode to get back into the phone, the LabTimers stop. They retain the position where they were when the lock screen went on, but no longer run. This is obviously a serious problem as it can ruin an experiment. There is probably a fix to this, as the built in iPhone timer continues to run in lock mode. LabTimers is really handy as you can set and run multiple timers, but this needs to be fixed.

Need choice of continuous alarm

Steve Mac since 1989

A louder and the choice for continuous alarm is necessary. A pause button would also be great. And the ability to have the names of the beeps indicate a little bit of the sound would also be nice. Beep-5 sound is really nice! Having landscape mode for the iPad is great. 5 stars with these improvements! 27 Jan 2013

Lacks 1 crucial capability I need


Need the option to keep your assigned name timer, the same length EVERY time... i.e. Timer 1 is always 3 hrs, Timer 2 is always 8 hours, Timer 3 is always 12 hrs. etc.
When you reset the timer now, it goes to 00:00:00... the option to keep any or all the same length would save setting the length of the timers after they expire
