## Units Reviews in United States

### *---- "Pro Ripoff"
I don’t know where all the positive reviews are coming from. As anyone can tell if they scroll down, the 1-star reviews are telling the truth - the app now does not perform any calculations, it only provides a description of each measurement.  
It then deceives you into leaving a “tip” to unlock more icons, but that’s all they are - different colors of the same app icon. It doesn’t actually enable you to access the calculations. People need to flood the App Store with 1-star reviews until they fix this issue.
-- GreatControversyExplainsIt, 2025-09-02

### ****- "Great, but Tips are per device"
One of my favorites, but Tipping for bonus icons is per device.  There’s no restore purchase option.  Makes me regret the tip.
-- Eastmarch, 2025-08-17

### ***** "Great app!"
This is my go to app for quick unit conversions. I like the option to reorder the converters so I can place those I use most frequently at the top. It’s simple, does what I need, and is free. What more could you want?

The only improvement I might suggest is to offer fractional amounts for length conversions in inches. If I’m converting 8mm to inches, knowing that 5/16 is 7.9375mm and 21/64 is 8.3344mm would be useful for making things with fractional measurements used on things like drill bits. I just use a chart to do that now, so it’s certainly not a deal breaker for this great app.
-- pogopogo, 2025-06-23

### ****- "Cups in dry Weight"
The only place I could find cups was in the Volume and Liquid Capacity. I was trying to convert grams of flour into cups.
-- duffystavern, 2025-06-13

### ***** "EV KW/h usage conversion"
Hi. I like your App. Its simple and useful. 
I would like to see a conversion for EV drivers to calculate mileage per KW/hr to kwh/100km etc. 
Thanks.
-- Papispunk, 2025-05-22

### ***** "Re-discovered this gem!"
I had this app on iPhone 3Gs and then haven’t used iPhones till the 11 and only just now re-discovered it on the 15. I am so glad this app is still available! There is nothing like it when you need it.
-- Kievguy, 2024-12-23

### ****- "Useful, just not intuitive"
It’s definitely useful, no doubt about that, it just is different to find anything you need.  I suggest a search bar be added at the top to find units of measurement and take you to where you need.
-- Leah Dykema, 2024-12-15

### ***** "Excellent App"
Clean and simple unit converter app updated for the modern iphone software look. works offline, and there a hidden conversions that you can find by selecting the edit button. PLEASE ADD SEARCH FEATURE!
-- kozuci, 2024-12-13

### ****- "Essential tool"
Great app and wonderful that it’s free. Would be nice to add AWG in length and area, and add a global search by unit for when you’re not sure what category to look in. Perhaps someday this will be open for contributions on GitHub?
-- NReilingh, 2024-10-28

### ****- "Great app"
I really like this app, but there is always something missing. Would it be possible for the use to create a custom list and conversation factor.  For me that would be even more useful.
-- Bubba Billy bob Jim, 2024-10-25

### *---- "Rope-a-dope"
Used to be free but new version locked until tip.  Opens app logos but still no access and resets to pre-tip if you reload app.
-- No Ohms, 2024-10-23

### ***** "Please bring back ruler!"
Have been using this app for nearly as long as it’s been out. Primarily as a ruler. Even though it was stuck in the old sizing, really liked that function. I know it must be difficult to address all the screen sizes now, but will definitely tip when that’s restored.
-- Undfeatable, 2024-10-20

### ***** "I like it but could use another liquid volume unit"
Hello! I’m writing this from the US, where we have weird units (I know, I know). Is there any way you could add the unit “acre-feet” to your liquid volume list? I work in water resources in the Desert Southwest and we regularly use acre-feet for calculating water pumping volumes for regulatory compliance. It’s an annoying unit but it’s way we’ve got here, where we seem to actively fear the metric system. Sigh.
-- Nerd of Rocks, 2024-10-10

### ****- "Improvement to be a great app"
1.  Decimal points round off in settings
2. Allow reordering and toggle together. Bring all the enabled units and measures on top.
3. Clear all button in the keypad
4. Icons beside units
5. Additional Foot+Inches (eg: 3.5ft=3ft 6in)
6. Additional Pound+Ounce (eg: 1.5lb=1lb 8oz)
-- Vasudev H V, 2024-09-22

### ***** "Love the 3.0 update"
Thank you for the update! Looks sleek. Have been using this app since 2009 and happily will continue to do so!
-- TFarron, 2024-08-23

### *---- "Forced donation!"
The app stopped working leaving only the dictionary of terms! It forced a donation to keep using the FREE app! I donated .99 cents and the app still no longer works!
-- Eriptron, 2024-07-21

### ***** "Good for Engineering"
I’m an engineer 
I love this 
The list of options is arguably overwhelming but I appreciate them deeply and find the vast majority not only helpful, but necessary
-- Engineer looking for tools, 2024-07-19

### ***** "Thanks for the update"
Congratulation for upgrade 3.0 it’s been a pleasure to see that these application has been updated since many years. I already support this. Congrats and keep this up to date.
-- Jaime Olmo, 2024-07-04

### *---- "Doesn’t work at all"
I can’t get to the option anymore where I put in the number of the units that I want to convert!   I thought maybe it required a tip, which didn’t help it to work.  I tried deleting the app and getting it again and it still doesn’t work.  For years it had worked perfectly
-- Mom mom mom mom mom, 2024-06-29

### ***** "I love this app"
I’ve had it on my phone for as long as I can remember and it has served me well over the years. Having a converter app that works without needing an internet browser or data connection is insanely handy in all types of situations. Recent updates have only made the app even better (I’m a sucker for a good dark mode).
