I have an iphone max 13pro. ### 3/5 — It works *2025-12-19, version 2.1.1* It works ### 4/5 — Simple & Nice ! *2025-09-21* Yes it’s simple , easy and nice. If only they given on the main screen an option to select say 4 of our frequently used units instead of going to the unit selection screen searching and figuring out the units….well it would’ve been awesome ! ### 4/5 — What happened? *2025-08-08, version 2.0.9* Yesterday it quit updating currency exchange rates. It keeps telling me to check my Internet connection, but nothing is wrong with my Internet connection. I have both data and Wi-Fi at my house. I have the pro version and I'd like for the currency to be able to be updated. ### 5/5 — Hola *2025-04-15, version 2.0.9* Excelente!! ### 2/5 — No Support *2025-04-03, version 2.0.9* I paid the $2.99 to unlock the Pro version on my iPhone. Then I downloaded the app to my iPad, and the app was wanting me to pay another $2.99 to unlock the Pro version. I tried contacting the developer support but without success. First, I was redirected to an unsecured website. Since I use a strong VPN, I took a risk and connected to the website. Then the button to contact support caused the website to freeze. The Pro version seems to work ok on my iPhone. ### 5/5 — Inquiry *2025-03-08, version 2.0.8* I bought the app and it didn’t appear or operate. What should I do now? ### 3/5 — Excellent. Easy to Use Features *2025-02-02, version 2.0.8* For converting many metric to US standards or in reverse THIS iS THE APP. With so many apps, it’s hard to know which ones are good. and in reverse- This offers so many options for area or temperature or whatever you need - quickly and easily. ### 5/5 — Unit converter pro *2025-01-12, version 2.0.8* Excelente! ### 5/5 — Been using this app for years! *2025-01-07, version 2.0.8* I cannot recommend it enough simple design easy to use.

No customization features ### 1/5 — Absolute Scam *2025-10-12, version 2.0.9* This App is not working properly. There are many values that are not converted. It seems it only converts range of values. GIVE MY MONEY BACK! ### 1/5 — 0 stars *2025-10-04, version 2.0.9* I tried using the app and the only screen I can see is to leave a review.
