I found it to be nearly useless **Developer response:** This app is free to use with having ads in the app, to remove there is an option to upgrade and get 8 more apps in the same price and help keep us building apps. Everybody want's everything for free, but don't think how developer who does it should live on free stuff. Store doesn't give anything for free even with by watching ads. Can't imagine how to live then if nobody pays you or watch ads. But looks like it is hard to make somebody happy without giving everything for free. Nowadays is how it is... ### 1/5 — Menu change *2023-10-07* Very difficult to change anything **Developer response:** One tap to search from main screen and one tap to get values from favorites sounds difficult. Either it was different app, or … ### 1/5 — No way to pay *2023-09-07* I just want to remove the ads. There’s an “Almighty” version that you can’t actually buy. The only accessible IAP is a $6/month subscription for a nine-app suite. Take a hike. Let me just subscribe, even yearly, to just this one app, as the App Store listing indicates. Without that, I’m taking my biz elsewhere. EDIT: Wow, what a rude response from the developer. Note that the App Store does indicate that there used to be an “Almighty” version, which in the leftover inactive UI in the app seemed to indicate it’s exactly what I want, and I’m happy to pay yearly for it - again, as the actual IAP listing shows used to exist. But the only way to pay in the current version is for a suite of all the apps, and only by month. No currency converter is worth $6/ month when I don’t have any use for the rest of the suite - that’s a ridiculous price. To be clear: your own app, and the App Store listing for the app, indicates there is IAP for me to pay yearly for this one app. You updated your app to remove this, selling only the monthly suite subscription, but left the UI and IAP listing for the now nonexistent version in place. You should probably get your act together. More than happy to take my money elsewhere. **Developer response:** Google about InApps and how AppStore works on side of the developer. And then learn about being obligate to provide you anything. We're not in a slave state to make what only you want. Grown ups don't like, they go further, others whine and blame others in your own problems and not being on time to buy when the proposition was available. It might be very miserable life to live like that. My condolences to you. Most funny part you never intended to buy, as if you would, you would already did that. Good luck! ### 3/5 — Exchange rate *2023-06-04* Displayed exchange rate is not current, it’s close but certainly of by 3-4 dollars. **Developer response:** Hi, Can you contact us at support@invoodoo.com as we update our currencies every 20 minutes. Would be great to see your problem. What currencies you've used to test? Thank you. ### 4/5 — I only downloaded because the dev snaps on complainers *2023-11-16* Seems like an ok app to me to me though. Hilarious! 😂 **Developer response:** Thanks for funny comment. As you can see a lot of people like it or even love it. But who likes it last time son’t write review. And somebody who didn’t spend a penny so entitled to write his opinion. Tolerance is good, when it makes sense. Too much of tolerance is really bad. If there is really a problem contact us, help improve, we’re open. But giving 1 star for spending 30 seconds in app. Why?! ### 5/5 — Just in time utility *2024-12-09* When a currency conversion is what you need, Convertium has your solution ### 5/5 — Money *2024-02-08* Money ### 5/5 — Easy to use *2024-02-01* Easy to use ### 5/5 — Sup bruh! *2023-09-06* Btuhhhhhj ### 5/5 — Solod app! *2023-03-26* I love that I can do conversions offline. Another thing is that the custom rate is available to save if needed. A solid app for sure. ## Most praised reviews (3 highest-rated) ### 5/5 — Just what you need *2023-03-10, version 1.0.1* Do what you need and more 👌🏻 ### 5/5 — Best and simple converter *2023-03-04* Everything you need! ### 5/5 — Simple and Easy *2023-03-04* Most quickest way to do any conversion.
