Stuck on volume conversions. ### 1/5 — Take your ads and shove it *2025-07-13, version 1.7.2* Adds you can’t pause or skip on a unit converter no freaking thank you ### 1/5 — False description *2025-03-23, version 1.7.2* This app lists “in app purchases “ but promptly takes $10.99 from Apple when you download it!! Talk about false advertising!! ### 1/5 — Was good, now totally crippled by ads *2024-08-19, version 1.6.9* I can’t even change the units any more.

Not impressed ## Most praised reviews (10 highest-rated) ### 5/5 — Very User Friendly *2025-09-20, version 1.7.2* 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. ### 5/5 — More useful than I ever thought use it all the time and it is teaching me how to convert from metric *2025-05-17, version 1.7.2* Great app ### 5/5 — Professor *2025-03-18, version 1.7.2* Very applicable ### 5/5 — Ability to Add and Cheap for the paid version *2024-09-15, version 1.7.0* 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! ### 5/5 — Miles & kilometers? *2024-09-14, version 1.7.0* 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 ### 5/5 — Owner/Landlord *2024-05-18, version 1.6.9* Couldn’t ask for better renters. ### 5/5 — User friendly *2024-05-02, version 1.6.9* Easy to use, I figured it out with no instructions and seems reliable. It’s my “go to” conversion app 😃 ### 5/5 — Great App *2024-04-29, version 1.6.9* 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. ### 5/5 — One of my favorite apps *2024-03-28, version 1.6.8* 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. ### 5/5 — Conversion App *2023-10-10, version 1.6.5* I only used it once, but I really like this one. I used it cause a recipe had pounds and the meat I was using wasn’t kilograms so I had to convert that and it was great --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
