I'm the builder behind Turnrow, and I wanted to share why we made this. University extension offices have done incredible work on agricultural math: gestation averages by breed, amortization schedules, grain bin volumes and more, but it almost always lives in a PDF or an Excel file that doesn't work on a phone with one hand in a calving barn at midnight. We kept running into the same thing: a rancher trying to figure out when his Angus heifer is due shouldn't have to download a spreadsheet. A farmer comparing two land loans before a banker meeting shouldn't have to create an account to do basic math. So I built Turnrow. Every calculator is: Free (no bait-and-switch, no trial) No account required - you get your answer and go Phone-first Fast - results come instantly Right now we have tools for cattle gestation, farm loan payments, grain bin volume, goat & sheep gestation, stocking rate, crop breakeven, moisture shrink, fertilizer rate, and more. We're based in Oklahoma and building more tools based on farmer requests. I would love feedback from the PH community - especially if you're in ag, know someone who is, or just appreciate tools that respect your time and don't demand a login. I'm happy to answer any questions below!
