Latest release

What’s New

Version 4.0.0 Dec 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!

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
