While the app is highly rated, some users might find the in-app purchase model, where specific features or ad removal are charged separately, to be less convenient or more expensive than a one-time purchase for a fully featured app.
There is a potential for the app to lack certain specialized units or conversion types that might be necessary for very niche or advanced users, which could limit its appeal to those with highly specific needs.
The requirement for Android 7.0 or higher might exclude older devices, limiting accessibility for users who cannot or prefer not to update their operating system.

Kim “Chogokin666”

Beautiful interface. Includes about every unit of measure I can think of. I switched from a unit converter that I've used for years but it was no longer compatible with my Android version. This has all that had and much more.

★★★★

Claire AuroraMagic

it's not as easy to use as the firat App converter which I can no longer find sadly. But this does the job and although I wish it defaulted to '0' so you can add the calculation you want and wish it had a favourite list to find quickly. It seems accurate and seems Very Good without any fuss nor adverts so for all that it gets a solid 8/10.

★★★

Great app for unit conversions. I bought Premium to get updated currency converter as advertised by the app itself. It doesn't work. The exchange rate is stuck to 09/12/25, like in the free version. Not worth it.

★★

Juraj Penciak

I purchased your app but I am not very happy with the currency converter. It doesn't update exchange rates. Today is November 26th but exchange rates are from November 17th.

App update not loading and requiring another app to be installed to read updated pdf file. I already have Adobe and I shouldn't be requested to install additional apps.
