And losing the ruler is the biggest down about this app ### 3/5 — What happened to Danish Kroner? *2026-01-18, version 3.0* I use the currency part of this app daily. Up until today, the Danish Kroner was included in the list of currencies. Are you taking out your Greenland frustrations on an app? ### 3/5 — Currency Conversion *2026-01-18, version 3.0* Conversion for Malaysian ringgit & Indonesian Rupiah are missing. ### 4/5 — Widget for conversion *2025-11-21, version 3.0* I recently did extensive traveling and the currency conversion tool was invaluable. However, many times when I went back into it, the main screen with all conversions displayed and I had to go back into currency. A feature to keep a particular conversion open or create a specific widget to access such would be really helpful. ### 4/5 — Great, but Tips are per device *2025-10-12, version 3.0* One of my favorites, but Tipping for bonus icons is per device. There’s no restore purchase option. ### 4/5 — Please add Nautical Mile to length *2025-10-11, version 3.0* We have parsec and nanometer but not nautical miles. Nautical Miles (NM) is used in piloting and we have a conversion for statute miles to nautical miles. Would be useful for flight-planning. ### 3/5 — Decent but clearly no longer maintained *2025-09-27, version 3.0* This app is fine for the most part, but has small issues that could make it better. For example, add the ability to insert commas on long numbers. For currencies, numbers should never be expressed in scientific notation. There are other small things but I have no hope of them being addressed because this is clearly an abandoned app. ### 4/5 — Incorrect Volume Conversions *2025-08-26, version 3.0* This app written in the UK apparently has 20 Imperial cups to an Imperial gallon. As a person who grew up using the Imperial measurement system I know that an Imperial gallon has 160 fl oz and 16 cups of 10 fl oz, 4 quarts, 8 pints… etc ### 4/5 — Great, but Tips are per device *2025-08-17, version 3.0* One of my favorites, but Tipping for bonus icons is per device. There’s no restore purchase option. Makes me regret the tip. ### 4/5 — Cups in dry Weight *2025-06-13, version 3.0* The only place I could find cups was in the Volume and Liquid Capacity. I was trying to convert grams of flour into cups. ### 4/5 — psi *2025-04-18, version 3.0* Absolutely love this app. Use it regularly. Just curious as to where I would find psi conversion? It’s not in Pressure where I thought it would be. Thanks. 👍🏼 ### 3/5 — Women’s shoe sizes incorrect *2025-02-24, version 3.0* 39 euro women’s shoe size is 8.5, not 7 Australian. Might want to check your conversions here. ### 4/5 — Useful, just not intuitive *2024-12-15, version 3.0* 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. ### 4/5 — Essential tool *2024-10-28, version 3.0* 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? ### 4/5 — Great app *2024-10-25, version 3.0* 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. ### 4/5 — I like this a lot *2024-09-25, version 3.0* It does what is advertised. I even gave a tip iin the tip area in settng. I do wish it had length mil and it is not the same as mm. 1 mil = 0.001 inch Thanks for the app. I hope you can add this soon. ### 4/5 — Improvement to be a great app *2024-09-22, version 3.0* 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) ## Most critical reviews (10 lowest-rated) ### 1/5 — Pro Ripoff *2025-09-02, version 3.0* 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. ### 1/5 — Rope-a-dope *2024-10-23, version 3.0* 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. ### 1/5 — Lists units but doesn’t convert them *2024-09-18, version 3.0* I should imagine that the most recent update has broken this and now it only lists unit names but doesn’t convert them. ### 1/5 — Forced donation! *2024-07-21, version 3.0* 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! ### 1/5 — Update *2024-07-13, version 3.0* V3 seems to have broken it ….. can’t close down settings ### 1/5 — Doesn’t work at all *2024-06-29, version 3.0* 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 ### 1/5 — Not working! *2024-06-02, version 3.0* App doesn’t work and is just showing a blank white screen since the latest update on my ipod touch 7th Gen. Please fix. ### 1/5 — Was great, V3 not functional *2024-05-27, version 3.0* I’ve been a user for too many years to count. Turned to this regularly and today it showed me V3 was available and now free, but it doesn’t work. What’s going on team, I’m sure there’s a s/w issue but no idea. Doubt it’s my hardware as I have the latest iPhone and update my system s/w regularly. Please fix this up so I can come back w 5⭐️ ### 1/5 — No longer converts *2024-05-09, version 3.0* The new update is not working on my iPhone 13 running 17.4.1. This has been a valuable tool that no longer works. Please fix and my rating will go back to 5 stars. ### 1/5 — Why no privacy info available? *2023-05-04, version 2.4.1* I just rechecked apps regarding privacy status. This one says no privacy info is provided by the app author. Seems kind of scary to me. Like giving some you don’t know a signed blank check and hoping it’s OK. Not worth what could happen. ## Most praised reviews (10 highest-rated) ### 5/5 — I’ve used this for years! *2026-03-25, version 3.0* Best app ever. ### 5/5 — This is so good *2026-02-17, version 3.0* I absolutely love this app. It can literally convert anything including currencies which is also up to date. God bless the developers. ### 5/5 — Great app! *2025-06-23, version 3.0* 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. ### 5/5 — EV KW/h usage conversion *2025-05-22, version 3.0* 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. ### 5/5 — Essential *2025-05-15, version 3.0* I use it almost daily, it so easy. Would be nice to have an EV option kwh/mile, kwh/100km, kwh/km, km/kwh, miles/kwh etc ### 5/5 — More Categories *2025-04-07, version 3.0* Add more categories/units like date/calendars with day, month and year pickers. Note though, that certain calendars like the Hijri calendar differ from one country to the other. For instance, one country may use a calendar, according to which, Ramadhan begins or ends one day early or late. ### 5/5 — Re-discovered this gem! *2024-12-23, version 3.0* 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. ### 5/5 — Excellent App *2024-12-13, version 3.0* 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! ### 5/5 — Please bring back ruler! *2024-10-20, version 3.0* 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. ### 5/5 — I like it but could use another liquid volume unit *2024-10-10, version 3.0* 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.
