chronometer

[kunst]

I am looking for a chronometer that counts days for my keyholder to know when my last orgasm occurred without having to look at the calendar every day and count the days. I have searched in Amazon but found nothing, only chronometers that count seconds and minutes.
Any idea?

I'm using a home-made speadsheet on drive.google.com.

There are a couple apps I noticed

For iOS, there's the Last Time app. It has an access-control PIN feature. I've been using it for a long time. You can record and track multiple arbitrary events, and add your own notes for each instance. There's a similar app for Android by a different developer.

There is Time Since Widget for Droid, Free one that just tracks one event or you can pay or more details.

On my phone I use Event Counter app for Android phones. Does multiple events with either a count up or count down feature and it's free. Displays Days, Hours, Minutes, no seconds
