It’s easy to use and very intuitive. It works perfectly, and I couldn’t be more happy with it. ### 5/5 — What a great easy app *2023-03-15* This is just a great, easy access app just when you need it. Free and does exactly what it should do. ### 5/5 — Great *2023-02-10* Great basic free calculator without all the ads. ### 5/5 — Big improvement *2022-12-14* Much better than the default calculator on my IPhone. Space bar is nice. Very clear and easy to use. So far, no ads. ### 5/5 — Génial *2022-10-14* Merci beaucoup aux développeurs, simple et surtout SANS publicités, je ne peux que recommander. ### 5/5 — La calculette avec la touche magique pour revenir en arrière ! *2021-11-01* Cette app a ce qu’il manque à l’app par défaut de l’iPhone. Quand on fait une faute de frappe on peut revenir en arrière grâce à cette calculette alors que dans l’appli par défaut ça efface tous nos calculs. Je rajouterai que le design est au top, minimaliste et sobre. ### 5/5 — 5 étoiles *2021-05-19* Simple et sans pub. Je recommande ### 5/5 — Enfin *2021-04-17* Simple et efficace sans pub. ### 5/5 — Parfaite *2021-02-28* Bonjour, Voilà enfin une calculatrice parfaite sans pub, sans populaire, sans truc qui bloque pendant que je m’en sert. C’est important pour moi, car je m’en sert pendant que je forme sur la licence radioamateur. Là, je place côte à côte la calculatrice et l’application de travail ou même l’application de stream et nous pouvons travailler direct. Continuez comme ça. Merci ### 5/5 — Excellent Calculator *2021-02-23* What an excellent calculator for the iPad Pro, I do all my calculations on it - Easy to use and brilliant 🌟 Kevin Barr kevinbarr.co.uk ### 5/5 — Superbe *2021-02-01* Très facile d’utilisation. L’affichage des opérations est intéressante en donnant la possibilité de corriger . Je recommande cette application. ### 5/5 — Evet *2021-02-01* Merci ### 5/5 — Super *2021-01-07* Très bien mais il y a pas la version blanc (le fond blanc). Je ne savais pas qu’une calculatrice prend que 410 ko! ### 5/5 — Une calculatrice sans pub *2020-11-07* Rien a dire de plus que dans le titre ! Elle devrait être en première choix et pas toute ces calculatrices avec de la pub ! Merci au déve 🍻! ## Most critical reviews (10 lowest-rated) ### 1/5 — Really? *2020-04-26* Doesn’t rotate and no scientific calculator... at least it has no ads... **Developer response:** Rotation has been fixed. Note: it is not a scientific calculator, juste a simple ad free calculator. ### 2/5 — Pink and green, really? *2021-01-11* Deleting app from my devices because the new color scheme in the last update is too obnoxious for me to view. I’m confident I can find a different app with a more mainstream presentation. Cheers. **Developer response:** Fixed.  New color scheme pink & green has been removed on Jan 13, 2021, version 2.1.1  Sorry about that. ### 3/5 — Not an iPad app *2019-01-09* Good basic clean and ad free calculator but is an iPhone app and does not support landscape mode. **Developer response:** Fixed. Landscape mode and iPad are now supported in the latest update. Thank you for your review. ### 4/5 — Good *2022-07-11* Wish it showed running total At least doesn’t stop mid-calc to throw in advertisements ### 4/5 — No ads *2022-01-18* Great simple app with no ads. Only problem is that is is missing a few features that could be useful, like an exponent option. ### 4/5 — Very basic - but completely free of garbage! *2021-05-27* It's a tiny app with simplistic functionality, but the clear interface comes without any of the common, irritating advertising rubbish which nobody ever reads anyway, making it very easy use. ### 4/5 — Pros & cons *2021-02-12* Pros: - no ads - no data collection - easy on battery life during extensive use - backspace - simple go-to calculator - easy to spot on the Home Screen Cons: - it has abruptly closed on me twice while starting it ### 4/5 — Calculette sobre *2019-08-08* App très simple et sombre la flèche retour et un plus que les autres non pas ### 4/5 — Calculator *2019-02-18* It would have been five stars if it would turn when you turn your iPad. I have to turn my iPad around to use it. **Developer response:** Thank you for your kind words. Rotation has been fixed on iPad. ### 4/5 — Overall good *2017-01-24* Love this calculator. Easy to use with backspace button. But missing press button sound. Hope to see it to the next version. **Developer response:** Thank you for your message. There will be an update with a press button sound this summer :) ## Most praised reviews (10 highest-rated) ### 5/5 — Clear & Easy to Read *2025-07-08* Thank you, Nice ### 5/5 — Simple *2025-05-08, version 2.1.6* Easy to use, very useful, better calculator with much less memory usage than iPhone or android pre-installed apps. ### 5/5 — Parfaite pour moi *2025-04-28* J’apprécie l’espacement des touches qui m’évite les fautes de frappe. ### 5/5 — X-pert for games *2024-12-18, version 2.1.6* I like Calc-right because it’s not just like a game.Better.Because it helps me no math and when there is a math component in school for my kids it would make it easier to understand.not like the other kids.and it will make it easier for kids games like todo math.and also it is ad Free.it also has a storage which you did a long time ago.for an example,on Mar the first calculation you did was 471+416=887.that’s why I like it. ### 5/5 — Avis calculatrice *2024-11-29* Elle est parfaite.
