LabCountimer

More than a lab timer: a timer and counter in one step. Count wash cycles, time incubations, chain them into reusable sessions — PCR, Western blot, ELISA, cell culture.

LabCountimer helps researchers manage overlapping wait times for PCR, Western blot, ELISA, cell culture, and other lab workflows. Every step can be a timer, a counter, or both — so one session captures "wash 3×, 5 min each," counting and timing together.

■ Key Features

• Run multiple timers and counters simultaneously
• Save chained sessions (reusable multi-step timer/counter workflows) as library entries

• Experiment history (Free: 7 days / Pro: no time limit)

■ Pro (one-time purchase)

• CSV export of experiment records
• Unlimited saves for your custom timers and chained sessions
• No time limit on history retention
• No ads

■ Privacy App-generated data (timers, sessions, history, settings) is stored on the device only and is not sent to external servers. No account required.
