Units FAQ
Is Units free?
Yes, Units is completely free and it doesn't have any in-app purchases or subscriptions.
Is Units legit?
🤔 The Units app's quality is mixed. Some users are satisfied, while others report issues. Consider reading individual reviews for more context.
"units" used to be a nice litte free utility, but "version 2.0" became useless junk. Nasty Ad always shown on bottom, unnecessary features (who converts electric inductance or air dencity in daily life?) and hopelessly unstable. Just to switch units (not even typing a single digit!) several times makes it crash on my iPhone3. Yes, iPhone3 is pretty old, damn slow and memory-restricted platform. So I had two choices; upgrade to iPhone4 to continue to use units 2.0 or uninstall it. I just uninstalled. Farewell units, you were a good application but not anymore.
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.
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!
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?
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.
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.
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.
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.
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)
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!
