Thanks! I used this app for android https://play.google.com/store/apps/details?id=com.kiss.countit, but any app that allows you to track with an opportunity to export the data should work just fine.
I then extracted the data to CSV and then did some processing on it.
I was thinking more in terms of counters with buttons.
I found something called Counter, but it really lacks polish. No dark mode, no widgets for individual counters, very limited statistics, etc.
But it's better than nothing, so I'll use that until something better comes along.
I used this app on my phone.

I used it as a widget and set it up with a counter for each type of significant object that I wanted to count (Neutron Stars, Earth-likes, terraformables, etc) plus an extra counter for each honk.
I still used a spreadsheet to calculate expected payout on return based on how many of each type I scanned - but that's because I was only in it for the money and the Elite rank.
I made sure my calculations were conservative to avoid disappointment and ended up with about 40m more than I'd expected.
If you are just asking for a simple counter app that has a widget, 'Counter' is a decent app. Not very pretty but it does have a widget feature. I'm sure you could find something else if you don't love that one.

I just used this app and would create a new counter for every oven, and tap the + every time I sucked down some delicious vapor :-)
I've never used it, but this app simply called "counter" looks like it might work
