Conversion Calculator Units reviews
4.7 out of 5, based on 7,397 reviews.
What people like
- Very easy and intuitive to use
- Perfect for daily metric conversions
- Combines conversion with simple math
- Great for travelers and expats
What they complain about
- Ads interrupt you constantly
- Ads still show after paying
- Hard to switch between units
- App crashes or rotates wrong
Very User Friendly
This is a great conversation app. You can access the measurements you want by side swiping and then create a list of favorites (your preferred conversions ) for future use by tapping the + icon. So happy I got this.
Confusing
Can’t change from volume to distance or anything. Stuck on volume conversions.
Great and easy
Great but whish it could be multi language, French at least But still great asset
There are ads
There are ads interspersed with the units of measurement which makes it very hard to scan quickly and interpret what you’re looking at. Also everything is in alphabetical order; you seem to be able to move some things around but I couldn’t change the initial order of Area, Energy Consumption, Length, which makes using this app involve a lot more scrolling than necessary. Deleting it for something else. Also the UI design is just ugly.
Great, but…
An excellent app, sadly captured by the in-your-face imperative of relentless and difficult to delete advertising. I’ll find another one that doesn’t try to sell me stuff I don’t need, and just does what I need.
More useful than I ever thought use it all the time and it is teaching me how to convert from metric
Great app
Take your ads and shove it
Adds you can’t pause or skip on a unit converter no freaking thank you
Yes!
Too bad the US isn’t WORLDLY! It’s the easiest way to keep up with the measurements of others. Now, if we all could value peace and show equality of all. This app helps us American dummies get with the rest of the world.
Great App..
A bit of confused GUI and still like features input/output copy/pate etc. would have added. A lot to grow.!
Ability to Add and Cheap for the paid version
Love the unit conversion and the ability to do simple math while converting at the same time. Only app I found that can do this seamlessly. Very affordable and love the features!
False description
This app lists “in app purchases “ but promptly takes $10.99 from Apple when you download it!! Talk about false advertising!!
Amazing I hope they keep
Great app I recommend to buy ad free to help them keep tip top. As this is most app’s eventual failure. I am willing to donate a nominal amount each year to keep at its best. Developer suggest to add a yearly 1.99 donate button. help keep at the top. keep up the good work
Needs pressure category
The title says it all.
Miles & kilometers?
It’s a great app except when it comes to length it doesn’t allow miles in kilometers. What’s that about? It ruins the entire app otherwise I would give it a Ford easy
Was good, now totally crippled by ads
I can’t even change the units any more. Uninstalling and moving on
Mr. lee
I love your app.
Klunky but works
I keep forgetting how to switch between different measurements. You have to swipe left on the top units header to get to different types of measurements.
Great App
I love it! It’s such a helpful app and I use it so much just for little simple convertions. Why? Because I was born in Mexico and now live in the USA and I’m constantly converting from metric to standard in weight, temperature and length values.
Grumpy crumpet
Awful. Prev app much simpler. I don’t like this
Handy app
Can’t believe how much I use this app on a day to day basis. And it’s even better when you remove the adds. 10 out of 10
Manquant
Superbe interface! Cependant, il manque une catégorie important: pression (pressure). Corrigez svp
One of my favorite apps
This app is awesome. For someone like me that moved to a new country with different types of measures, is the best app ever. Super easy to use. Love it and recommend a lot.
Like
Great app without ad
Ads are annoying
The only thing I don’t like is the ads. And I think it’s missing a pressure conversion: psi to bar or Kpa
No forces
No convertion for convertion
Awesome app
Awesome app for apple
Trop compliqué à utiliser pour conversion de température
Laryque
Needs a pressure category...
p.s.i., p.s.f., in. water, in. Hg, mm Hg, kPa, hPa, atm., bar Otherwise, useful.
I use this all the time
I use this all the time for work and on vacation. Trying to learn the metric system. This is a great tool. Even paid to remove the advertisements!
No portrait mode
When I rotate my iPad to portrait mode the app stays in landscape mode. Worse still, it can flip upside down, usually when I close an ad too soon, and it refuses to right itself without restarting. Uninstalled.
Pretty good, it's free, but one request
It'll be really useful if in the lengths category you could make it Feet and inches instead of them being separate.
Review
Simply the best
Difficult to operate
Difficult/impossible to change conversation functions. Help page not helpful.
Really Nice
I have tried quite a few Unit Converters and this is one of the best. It doesn't have reams and reams of categories but that's good - it probably has all the ones any normal person might need and so it helps to keep things simple. It's execution is rather good - intuitive and therefore easy to get to grips with. Unless you're a Rocket Scientist or Nuclear Physicist, then this will probably do you very well.
This thing is great
I am constantly doing nautical miles to meters and knots to meters per second in programming as well as gallons to liters and this is super handy. And it’s quick
Disappointed
Downloaded this yesterday and paid to remove the ads. Opened it this morning and they’re all still there. Will give it 24 hours to see if they’ve gone and will post another review Payment taken through App Store but still seeing ads. No response from developer. Not impressed
Ottima
Ottima e completa!!!
