I love the themes. Great work guys!. I’m waiting for your next app :) ## Most critical reviews (10 lowest-rated) ### 1/5 — Changing to something else *2024-05-29, version 2.0.4* This does not have psi, kpa, or other pressure conversions anymore. ### 1/5 — Not useful, I can't convert 1mm to inches *2023-01-22, version 2.0.3* Ppiittuuutttooo32As ### 1/5 — Metric to imperial format is not what people use *2020-10-03, version 2.0.3* When one needs to convert from metric to imperial, one does not use decimals but rather fractions ie 594 mm = 23 3/8 inches not reported by this app as 23.38582677 inches How useless is that? ### 3/5 — Decent *2024-10-17* App is a good start compared to others. Looks good, but could have some functionality added to make things easier. Also it definitely needs pressure units. ### 3/5 — Works but could be easier *2024-04-15, version 2.0.4* Works pretty well but if you are going back and forth between 2 units you always need to choose which ones. Would be great to add the reverse button. ### 4/5 — it's got it all *2024-11-03, version 2.0.4* in a really hard to use interface. simplest improvement for this app would add a favorite conversations. having to manually navigate the drop downs all the time is a huge drag. maybe color code the different sections too. help my brain remember where to do certain tasks. ultimately searching google is just faster and easier.. ### 4/5 — It’s great! *2022-10-13, version 2.0.3* I’ve been looking for a unit calculator/converter and I found one (this)! But it doesn’t have all of the units but I love it! ### 4/5 — Great app, but PRO version got app’s ads! *2022-02-15, version 2.0.3* I think this would be nicer to have an pro version without app’s ads! Also should integrate money conversion to be complete at hundred percent! ### 4/5 — Could be easier to use *2020-12-20, version 2.0.3* Fussy to pick the kind of unit and scroll to the right to and from units each time. It would be great if recently/frequently accessed conversions were a single tap or easier to access. But it’s a useful app. ### 4/5 — ?! *2020-08-08, version 2.0.3* I T I S V E R Y C O O L !!!! YOU KNOW ?! INSANE!??’ ## Most praised reviews (10 highest-rated) ### 5/5 — Converter Application *2026-08-27, version 2.0.4* A very simple but excellent unit converter application to make convenient and easy for people traveling to see the units in their home country specifications.
