What's New in CONVERT UNITS

1.3

September 8, 2026

Ads can now be removed. • One purchase, or a monthly subscription, hides the banner — and gives its space back to the converter. • Everything else stays free: every category, unit, currency and language. • Restore a purchase any time from Settings.

Response from developer

We are genuinely sorry about this that we are removing any mature content that is being shown by google ads. We didn't realize that google ads was doing this.

Ditch the sexist banner

In most respects this looks like a good, useful unit converter. But WHY the sexist banner? Can’t you at least provide an option for getting rid of it? I’d gladly pay.
