## What is LabCountimer?

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
- Completion notifications (works in the background)
- 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.

The free tier shows ads via Google AdMob. The ad SDK may process device-level data per Google's policies. The Pro tier shows no ads and makes no ad requests.

■ Disclaimer
For research, education, and lab workflow timing only. Not intended for medical, clinical, diagnostic, therapeutic, drug-dosing, or regulated laboratory use.
