LabTimer is a count-up and alarming count-down multi-timer. ***NEWS*** LabTimerPhD is now available. It has all the same functionality as LabTimer. If you like LabTimer, please consider picking up LabTimerPhD! I'll use the suggestions on LabTimerPhD for future changes. All updates will be applied to both applications. ***NEWS*** The look and feel of LabTimer is designed to emulate that of standard lab timers, providing quick access to count-down timers and repeat runs. LabTimer is not just good for the lab, though - it is also convenient for cooking, medication timing, working out, and child timeouts. LabTimer has the following features: - Four timers, individually configurable as count-up or alarming count-down - Large display and buttons - Display in Hours : Minutes : Seconds (limit above 1000 hours) - Customizable text labels for each timer - 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-down timers each: - Display the projected finish time - Alarm for one minute - After the alarm, display the time elapsed since finish in red - Repeat the last count-down by: -- pressing clear while the timer is paused -- pressing start/stop twice after the timer has finished The iPhone currently prevents background processes, so LabTimer cannot alarm if the application is not running. However, 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 LabTimer, and we hope you will too. LabTimer is free and will remain free. I've created LabTimerPhD, a pay app with identical features, if you'd like to contribute to future development. I haven't seen anyone else doing this and it seems like an interesting way of handling donations. :) Please let me know what you think and how LabTimer can be improved, either via a review or the e-mail address on the website. Thanks for looking!

Boiling an egg, timing a presentation, or starting your next Pomodoro – Disco Timer is a universal countdown clock for all sorts of tasks. Setting the timer duration is based on 60-minute circle of traditional analog watches – you just wind it up with a single rotary gesture. Then tap the display to run, pause, or reset the timer. Large, high-contrast representation of the remaining time makes it glanceable from quite a distance. And an option to disable the Auto-Lock can keep the device awake while the timer is running. This comes in very handy when keeping an eye on the progress is as important as the finishing time itself. The face of the timer can be customized by choosing from a variety of color combinations (Premium feature). And for the completion alert – you can select from a dozen great-sounding tones, all of which are crafted exclusively for Codulis apps. Give Disco Timer a try, and let us know what you think!

Verdict

The call

The clearest difference is rating: Disco Timer at 4.7 against LabTimer's 4.0. Disco Timer also leads on update cadence (every 5 months vs every 11 months). LabTimer's advantage is in-app purchases (none vs 1) and iOS requirement (10.0 vs 15.4). On price, review sentiment, ratings volume and ads there is nothing between them.
