Would be helpful to enable alpha sorting at a minimum. Would be even more helpful to have a manual ordering option. ### 4/5 — Unités manquantes *2025-08-21* Très bonne app. En revanche pourquoi les unités centilitres et centigrammes ne sont pas présentes dans la liste du convertisseur ?! À corriger. ### 4/5 — Great. One Star Off for 1 Reason *2025-08-16* I like this app. I purchased the lifetime license to remove the ads. It is superior to the stock calculator in most ways. My only request is for the developer to add a swap button on the currency calculator so we can easily swap between currencies for example USD > DOP and the swap button to quickly switch to DOP > USD ### 4/5 — A really good app but... *2025-02-28, version 1.5.3* I think the underline is unnecessary on every button,hope they can be removed in future ### 4/5 — Pretty good but… *2025-01-20, version 1.5.2* Could be better if it had percent increase or decrease calculation. That would make it worth 5 stars for me. ### 3/5 — Fair *2024-12-15, version 1.5.2* Ok but not great ### 4/5 — Great all round with one fault *2024-11-15, version 1.5.2* Well laid out. Really good colour schemes and we'll thought out functions. Only downside is when open will keep iPhone screen fully awake so if you forget to close the app page thee screen remains on ### 2/5 — Les pubs malgré l’achat *2024-08-24* Rien à dire sur la ou plutôt les fonctions de la calculatrice. Très complète. Par contre, que des écrans de pub s’intercalent dans une phase de calculs alors que j’ai acheté la version sans pub. C’est nul !!! **Developer response:** l'application payante est une application différente. elle s'appelle OneCalc+ sur votre téléphone. veuillez vérifier que vous utilisez la bonne application. ### 4/5 — Great calculator that does most with one big flaw *2024-05-24* This is a really good calculator. It looks good and has many functions not expected. It would be great if there was a widget but it's biggest drawback is it never goes to sleep and will keep the screen on until closed. Looks like no updates for some time ### 4/5 — Themes please *2024-04-26, version 1.4.7* All is good. But can add more themes? Or custom theme for users to set. Thanks ### 3/5 — Great Calculator… but…. *2024-03-02* Lot’s of functions - easy to use abd nice features such as the history of calculations. I do have a couple of reservations: the systematic underlying of every number and symbol on the calculator is very annoying abd distracting but it cannot be removed. So the minus sign, for example, looks like an equal sign because it is underlined. The other reservation us the lack of choice of a “skin”. It shouldn’t be hard to add a few. ### 5/5 — Square roots *2024-01-29, version 1.4.7* Can’t find the square root button, where is it please? ### 4/5 — Works very well and has one issue. *2024-01-28* Everything is working fine except the currency converter which is not getting the latest exchange rates. ### 5/5 — Super smooth *2023-12-12* A very convenient interface. No fuss and absolutely worth the money. Although unable to share the purchase with family i wonder why ### 5/5 — Easy to Use *2023-11-24* This is definitely the best digital calculator I’ve ever used. It displays step-by-step calculations, which are saved until you’re ready to delete them. And there are more features available than this old guy will ever need or use, but they’re out of the way until you need them. The buttons are large enough to fit my fat fingers, and the calculator is nice looking. You can use this calculator for free, if you don’t mind watching a short video or two. But, for less than the price of a cup of coffee, you can get the paid version. While I didn’t mind the videos, I paid the small purchase price, because it’s obvious that a lot went into the development this little gem. Give this great little calculator a test drive. I’m sure you’re going to be happy with it. ### 4/5 — Good but,.. Some items missing *2023-11-15, version 1.4.7* Widgets are missing 😖 a calculator and items in "favorite" should have widgets! Also it would be nice to have other spot prices like oil, gold metal etc (instead of only currencies). Common developer,.. Look at calzy, clevCalc and other dinosaurs 😅 ## Most critical reviews (10 lowest-rated) ### 1/5 — Complicated *2024-07-30, version 1.5.2* Complicated, I keep going back to my free one! ### 1/5 — No realiza operaciones complejas correctamente *2024-03-16, version 1.4.7* Resuelve las operaciones complejas en el orden en el que estas están escritas, sin respetar ni los paréntesis ni la jerarquía de las operaciones. Por ejemplo 6:2(1+2) le da 9 i no 1 como debería. Una estafa. ### 1/5 — There should be more background colours for dark mode. *2024-02-26, version 1.4.7* There should be more background colours for dark mode. The recent one is okay but its too dull and the colours are not too good. Different colours for dark mode are needed. Thank you, Your Customer. ### 1/5 — Charged for Ad Free Version but still receiving ads *2024-02-15* Paid for Ad free version and still receiving ads??? **Developer response:** The paid app is called OneCalc+. Please check that you are using the correct app. ### 1/5 — Paid but still get ads *2023-05-31* I paid for add free use but I still have adds pop up after. Please investigate and fix. Thanks **Developer response:** The name of paid version is OneCalc+ on the phone. Please check that you are using the correct app. ### 1/5 — 계산식 수정기능이 없네요. *2022-08-21, version 1.4.0* I cannot paste the calculation in the clipboard. You need to check your app. ### 1/5 — App Icon *2022-03-23, version 1.3.8* I paid money for the full app please remove that ugly star from the middle of the app icon. It looks ridiculous. Maybe add a few extra icon theme options so my Home Screen doesn’t look stupid Thanks ### 1/5 — Purchased this app… still has adds *2021-07-31* Purchased this app… still has adds **Developer response:** The icon on the paid version has a yellow star on it so as to distinguish it from the free version. Please check that you are using the correct version. ### 1/5 — Don’t use its fraud calculator *2020-11-15* I bought it but still ad appears **Developer response:** Please check that you are using the correct version. The icons of both free and paid version looks similar. The paid version has a yellow star on the icon. ### 1/5 — No value for money *2020-10-21, version 1.3.2* Even after purchasing shows ad soo annoying ## Most praised reviews (10 highest-rated) ### 5/5 — Best calculator *2026-06-10* UPDATE: I really wish there was a pause in clearing the history. Like a button to confirm. I hit it on accident a couple times and had to redo a large amount of transactions. the Great product. I bought the ad free one, but apparently it does not erase the ad one when installed. I had two and kept seeing ads. Finally figured it out and deleted the ad one. Weird way to build it. ### 5/5 — Best calculator *2026-03-30* Great product. I bought the ad free one, but apparently it does not erase the ad one when installed. I had two and kept seeing ads. Finally figured it out and deleted the ad one. Weird way to build it. ### 5/5 — Very useful *2026-03-14* Great easy to use calculator. With lots of bonus calculations you get included. No brainer don’t have to remember formulas, you get the answer you need with just inputting values. I like its simplicity and any highly recommend for quick one offs. Soulver is also good for more involved tallies with persistence ### 5/5 — No Ads, No Tracking *2025-09-18* Great calculator. Modestly priced paid app. This app is what I would have expected as a default app on my iPhone. Sadly, Apple failed me there. But this app is great. No ads. No tracking. (Again, talking about the paid version.) Just a good calculator app. Highly recommend. ### 5/5 — Très bonne appli *2025-08-12* Très utile ### 5/5 — Personal Fav *2025-07-14* I’ve downloaded a lot of calculators over the years but this one seems to have everything I could want. The vast array of unit conversions is really nice. One function that pleases me is the ability to calculate very large numbers - into the billions - a place where others calculators toss out error codes. ### 5/5 — Absolutely a great calculator. *2025-01-09* I’m going on 4 years using this calculator. The extra functionality for figuring temperatures, distance, etc makes it a an exceptionally useful app. ### 5/5 — Love this calculator *2024-09-01, version 1.5.2* All in one calculator is my favorite. ### 5/5 — Best calculator you could ask for *2024-07-03* Easy to use and very helpful with so many different ways to use it. Whoever figured this thing out should be commended. ### 5/5 — Thank you! *2024-03-15* Spent a long time looking for an app this good. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
