User Reviews

Users praise the app for fast, reliable, easy, all-in-one metric/imperial conversions (temperature, distance, weight) and find it practical and handy. The main downside is pervasive advertising, with some reports of ads continuing after paying and occasional explicit ad content, which can disrupt usage. A paid, one-time option to remove ads is highly valued by those who purchase.

Pros

Quick and reliable conversions
Easy to use with an intuitive, all-in-one calculator for metric/imperial conversions (temperature, distance, weight)
Instantaneous results and handy for everyday use and teaching moments
Useful across multiple units and contexts (home, school, travel)
Paid, one-time option to remove ads is valued by users who purchase

Cons

Ads are intrusive and pervasive in the free version
Ads can persist even after attempting to pay or switch to ad-free, disrupting usage
Pornographic or explicit ads appear, which is unacceptable
Pop-ups and ad links sometimes lead to sketchy sites or misleading close buttons
For some users, the ad-heavy experience makes the app feel not worth it unless heavily purchased

Recent reviews

Used it for years, always quick and reliable, never a bombardment of ads, on and off so quickly after my conversion, rarely is an ad presented.

by Pe*****, 2026-05-03

Excited to try the app, and was willing to try with ads for free. However, I could even exit the ad when it finished to return to app. I closed and reopened the app, only for another ad to pop up before I could even try it out. I deleted the app immediately after.
