What's New in Unit Converter

4.0.0

December 10, 2025

Once again... long time no see! Since my last update, I've switched companies and finalized plans to move overseas. OmniConvert 4.0 includes some changes that I think everyone will be happy about. For the free users - ads are now gone! I don't think the incoming ad revenue justified the annoyance I'm sure they imposed for the average user, so I got rid of them. For the pro users, there are two new pro-only conversions (Angle + Frequency) and one new calculator (BMI). I've also made some app-wide improvements and bug fixes that should improve everyone's experience. You can also (finally) reorder your favorites!

Essential

I couldn’t have made it through med school without the medical section of the app! Everything’s super intuitive and up to date.

Great job!

I’ve been with iOS since the first iPad and can’t believe it’s taken this long to discover a free and data friendly converter app.

Everyone: check his profile and if he’s local, buy him lunch.

Best Converter App For iOS

This app blows the others out of the water. Clean, minimal, and effective design. I like the timestamp signifying when currency rates were last checked. Extremely useful during foreign travels!
