SpliTTime

Calculate the time to split your cells. A small, focused iOS tool for people who actually work at a bench.

SpliTTime

Every cell culture protocol comes down to the same question at the end of the day: when do I need to come back? You know your current confluency, the split ratio you want, and roughly how fast this line doubles. SpliTTime turns those into the exact hour, so the timing is settled in seconds and a long day never has to end with math done by hand.

SpliTTime does that one calculation, correctly, in about four seconds. Enter confluency now, the split ratio you are aiming for, and the doubling time of your line. It returns the hour to come back.

One calculation, done right

Confluency, split ratio, doubling time in. Time to split out. No menus to hunt through.

Works offline, on-device

No account, no network call, no data leaves your phone. Tissue-culture rooms have terrible signal anyway.

Built by someone who did this

Written by an MD-PhD who spent years in a genomics lab passing cells. The defaults are the ones you actually want.

Why a whole app for one equation

Because it is the calculation you run the most, at the end of the longest days, where the timing matters most. An overgrown flask is a lost week. A split done six hours early is a lost passage. SpliTTime keeps that timing exact so the science stays on schedule.

The lab’s position on small tools is simple: they should stay small. SpliTTime has no account system, no social feed, no subscription, and no notifications begging for your attention. It does one thing and disappears. That is the whole product philosophy, and it is the same one behind MoleMixr.

Privacy

SpliTTime performs all of its arithmetic on your device. It collects no personal data, requires no account, and transmits nothing. Read the SpliTTime privacy policy for the full statement.
