Read full description

Scientific Timer helps researchers keep complex experiments on schedule. It breaks multi-step protocols into timer-tasks, so every incubation, wash and spin gets its own timer, in order, and you always know what comes next. Tired of juggling kitchen timers across the bench, or losing track of which tube went in the centrifuge when? Start from a curated protocol or build your own, then run as many timer-tasks in parallel as your experiments need. FEATURES PROTOCOLS AS TIMER-TASKS Each step of a protocol becomes a timer-task with its name, duration and position. Start, pause and reset each one on its own, and see its progress at a glance. CURATED PROTOCOLS, READY TO RUN 12 protocols with 211 timer-tasks, already set up: 10x Chromium Single Cell 3' Gene Expression v4 and 5' Gene Expression v3, 10x Xenium In Situ Gene Expression, ScaleBio Single Cell RNA Sequencing v1.1, Twist Library Preparation EF 2.0, Beckman Coulter SPRIselect left-side and double-sided size selection, Qiagen QIAamp DNA Micro, Qiagen RNeasy Midi/Maxi, NEB Ligation, immunofluorescence on frozen sections and trypsinization. Choose the ones you use when you first open the app, and change your selection later in Settings. YOUR OWN PROTOCOLS Create protocols and timer-tasks of your own, up to 24 hours each, as a countdown timer or a stopwatch. Put steps in the order you run them and mark your favorites. RUN MANY AT ONCE Run as many timer-tasks in parallel as you need, across several protocols. Timers keep counting while the app is closed, and a timer that passes its target keeps going, shown with a "+", so you know exactly how far over it is. QUIET NOTIFICATIONS A subtle notification on your iPhone tells you when a timer-task is done, instead of another alarm ringing across the lab. SEARCH Find a protocol by name in your library, or a timer-task by name within a protocol. BACK UP AND SHARE Export the protocols you created to a file, and import them again on another iPhone or share them with your lab. ACCESSIBLE TO EVERYONE Works with VoiceOver and Voice Control, adapts to the largest text sizes, supports Dark Mode, respects Reduce Motion, and does not rely on colour alone. PRIVATE BY DESIGN Scientific Timer collects no data. No account, no sign-in, no analytics, no tracking, no third-party SDKs. Your protocols and timers stay on your iPhone. LANGUAGES The app and its curated protocols in English, French, Spanish and Simplified Chinese. REQUIREMENTS iPhone with iOS 18 or later.
