## Unit Conversion Description
This application offers quick and easy conversion of units. 16 different unit categories are supported, like temparature, currency, distance, weight, volume, ...
In addition the app offers a calculator. You don't have to switch any more between conversion and calculation apps.
There are even two calculators included, a standard and a scientific one.
Units are sorted by frequency of usage, the units used most often show up on top of the list. No need to scroll anymore to find your favorite units.
Programmable buttons make it possible to access your favorite conversion units even faster.
All functionalities are accessible on the main screen, no need for tedious switching between sub-screens.

List of supported unit categories:
- currency (live update)
- temperature
- distance
- weight
- volume
- time
- surface
- speed
- angle
- data storage
- energy
- power
- pressure
- concentration

Features:
- simple and intuitive user interface

- units are sorted by the frequency by which you are using them. The units you are using most are shown on top. This allows much faster working.
- live update of currency conversion rates
- programmable buttons: save your favorite unit conversions on these buttons for faster working.
- swap key, for fast swap of the 2 selected units
- all settings are saved when leaving the application

Instructions:
The programmable buttons are the blue buttons at the top. Hold one down until you hear the beep and the selected units will be saved on this button. Press the button again for fast recall of this unit pair.

## Unit Conversion Reviews in Vereinigte Staaten

### ***** "Very simple"
The most reliable go to unit converter ever! Love it!
-- Buller 27, 2022-09-21

### ***** "Really helpful"
This app is probably the one app I have used the longest. I have used it in so many situations. I use it in my personal life and on the job.
-- Tiger  W, 2022-02-21

### ***** "So useful"
Well, it’s definitely a must have. Ideal for folks that work with US and Imperial and KG measures. Easy to use and fun.
-- the Fact & All, 2021-05-18

### ***** "Love it"
Very intuitive and easy to use.
-- SgtMac, 2021-04-27

### ***** "We need an update to the new IOS, please!"
We need an update to the new IOS please
-- JOseDurand, 2020-12-31

### ***** "Convenient"
Handy
-- DeepblueKat, 2020-05-17

### *---- "Useless calculator function. Don’t bother."
This is one of the few converter that offers a built in calculator. Unfortunately, it’s useless if you want to manipulate the value on the right in the calculator.
-- vferdman, 2019-12-22

### *---- "If it costs money, it should be complete."
Seriously... no cubic inches, feet, or yards????
I haven’t checked the other conversions, but what are they missing? Refund my money please
-- Myyellowlab, 2019-07-24

### ***** "I Like it!"
I have a few other conversation apps, but I always end up using this one. It works & I use it often for a lot of different things. It’s never let me down. Accept for having to choose a nickname for writing this review..., several names I wanted were already used. This is nuts. I’m beginning to think there is a flaw in the software.
-- 7/9/19, 2019-07-10

### ***** "Great app"
Really useful!
-- abacero, 2018-11-11

### **--- "Perfect app that was ruined"
The old version of this was perfect; I used it all the time, daily.  Now they've added ads that keep getting in the way, and pop up too frequently.  I would pay for an ad-free version, but they don't  offer one.  And the ads keep getting longer, something that discourages me from using it to quickly double-check a measurement.
-- TuxedoCartman, 2017-07-04

### *---- "No memory of last position, one way conversion"
I have the no-ad purchased version. 

The app has no memory of your last conversion when exiting and reentering the app, so for example if you frequently convert from Sing dollars to Euro you have to find and select the currencies in the list every time to re enter the app. 

It only converts left to right. There's no reverse conversion. So to go the other way you have to search and select the reverse conversion. 

The default decimal precision seems a bit much (to the millionth!). 

Other than those show stopper issues, it does conversions well.
-- eflo200, 2017-06-08

### *---- "Full of pop up useless ads"
They're forcing us out of the free version by putting too many annoying pop-up ads from K. Kardashian, Wishbone, etc. constantly. Unable to start conversions until you close the ads. The app has peaked & isn't making money. USELESS & ANNOYING. $.99 version will probably do this soon.
-- Eclectic & Co., 2016-09-24

### ***** "$.99 version"
To all of you frustrated with the free version of this app, it's time to pay $.99 for the add free version. The free version has been rendered useless by the adds invasion. Out of frustration I deleted the app. I have not seen any adds in the paid version so far.
-- Renewable Energy Guru, 2016-08-28

### ***** "Easy to use"
Simple and intuitive. I don't mind the ads and to be honest I don't even notice them. I don't have many apps on my phone but the ones I do have are indispensible. Great app, please don't change a thing.
-- 145CA, 2016-07-07

### ****- "Good To Have Available"
It's quick & easy & accurate. The ads are a waste of time.
-- Just Plain Old, 2016-06-10

### ***** "Very useful!"
That app is easy to use and very, very useful!
-- AtalantaAsh, 2016-04-28

### ***** "Love this app!"
Easy to use and has every possible unit of anything you'd ever want to measure and then some!
-- Binky T. Wonderdog, 2016-04-11

### ***** "Nice"
I use this app more than any other.  And it is the best I have ever seen. Only thing I wish was that the currency conversion would remain visible when not connected to wifi
-- Vurtone, 2016-03-30

### ****- "Awesome but ads are too much!"
I absolutely love this app but the ads are too bothersome right now. At the beginning the ads were tolerable-a banner at the bottom, but recently the video and audio ads I have to suffer through before using the app have become too much! Get rid of the ad barrier and I'll give it 5 stars!
-- Edosan70, 2016-02-28
