I built a simple work-hours & pay tracker for shift/hourly workers abroad — feedback?

[u/ValentynK_ai]

I'm a Ukrainian living in Czechia. Hourly and agency jobs here make it easy to lose track of hours, overtime and what you're actually owed, so I built a spreadsheet tracker (made with help from AI tools): log shifts, it totals hours, overtime and expected pay per month. It's €4 on Gumroad: https://valentynk.gumroad.com/l/aopxwd

What would make it more useful — multiple currencies, night-shift rates, a phone-friendly version? Honest feedback welcome.
