Sketchy at best. App itself is basic but useful with both a memory and history function. ### 3/5 — 背景の *2025-10-26* iPhoneの電卓が使いにくいのでこちらを選びました。 背景の色を変えることができますか？ 変えられたら星5です。 **Developer response:** [☰]ボタンを押すと電卓のテーマが変更されます ### 5/5 — Ideal *2025-02-25* I was frustrated with the latest basis iPhone calculator and wanted a nice clear calc that behaved like I expected. This does just that! ### 5/5 — Kukaj *2025-02-20, version 1.8.3* Karkulačka je tak tak ### 4/5 — 電卓専用器と同じ感覚 *2025-02-02, version 1.8.2* 電卓らしい見た目 ### 5/5 — math *2025-01-30* is super duper ### 5/5 — Prettiest thing *2025-01-21* This calculator is very pretty ### 5/5 — おう👑👑👑👑👑👑👑👑👑 *2025-01-14, version 1.8.2* おっすだや おう げんきか？ おう あいしてらや おう たげいいあぷりだや ### 5/5 — Great - except for one detail *2024-11-12* This is a great calculator but why is there a 00 button and if there is one it should be where the 0 button is. More natural…. **Developer response:** You can toggle 0 and 00 keys from the calculator menu ### 3/5 — Cal. *2024-11-05* Good ### 5/5 — 使いやすい！ *2024-11-02* 普段、日常的に使用している電卓と似ていて、違和感なく普通に使えて使いやすいです！ ## Most critical reviews (10 lowest-rated) ### 1/5 — Be careful: Porn *2026-02-02* The first advert that came up was naked women ### 1/5 — Hidden porn *2025-11-27* Beware this app has hidden pornographic pictures now in the advertising bar 😢I have been using for a while but recently these images have been appearing. I ha e now deleted the app **Developer response:** Sorry to hear. We have no control of the ads as it is provided by Google. You can report the ads by pressing the ⓘsymbol on the ads. Our team will also monitor this. ### 1/5 — キー表示にアンダーバー下線 *2025-10-30* 以前から使いやすくて助かっていましたが、いつのまにか表示がおかしくなりました。キーの文字全てにアンダーバー、下線がつきますね。とても見辛いので困ります。 **Developer response:** この動作はiPhoneのアクセシビリティ設定によるものです ### 1/5 — معكوسه *2025-08-21, version 1.9.4* معكوسه بالعكس المفروض علامة الجمع والطرح والقسمه تكون على اليمين ### 1/5 — ゴミ *2025-08-06* このゴミアプリ ### 1/5 — 広告多すぎ *2025-08-03* 広告多すぎ ### 1/5 — Payment not removed ads *2025-07-29* I have paid for ads to be removed, but i still have annoying ads. This is unacceptable. There appears to be no method of help on this. **Developer response:** The paid version has a yellow star on the icon. Please check that you are using the correct app. ### 1/5 — แก้ไข app เครื่องคิดเลข *2025-03-03, version 1.9.1* ดิฉันสามารถย้อนคืนเวอร์ชั่นก่อนหน้าที่เป็นตัวเลข Size เดิม ควรดำเนินการแก้ไขอย่างไรคะ ### 1/5 — Inappropriate Ads *2024-10-11* Hi I have been using app since a while. Please screen which ads before you put them. Using calc in front of client and its displaying inappropriate ads in between. Very disappointed and uninstalling your app. Hope you do something about it. ### 1/5 — 宣伝過多 *2024-10-10* 宣伝多過ぎてストレスです。 ## Most praised reviews (10 highest-rated) ### 5/5 — Easy to use *2026-06-20* Very easy ### 5/5 — Best one in the market, worth the money! *2026-04-07* As an accountant I definitely recommend this calculator to everyone. This has a double-zero button (along with single zero) and memory functions and bunch of themes if the standard looks boring! ### 5/5 — Simple Calculator *2026-01-01* Does exactly what the title suggests. Good for the elderly who have difficulty using modern machines. ### 5/5 — いいねー！ *2025-11-19, version 1.9.4* いつもの電卓 いいですよー ### 5/5 — 最高 *2025-11-15* 無料の計算機で一番使いやすい ### 5/5 — Thank you so much *2025-11-07, version 1.9.4* It’s really useful for business ### 5/5 — ‘▶’ issue *2025-08-15* The ‘▶’ key does not work after pressing the formula and '=' key. ### 5/5 — upgrade *2025-08-03* Following recent feedback I have now learnt that after paying you need to download the version with a yellow star icon. All fine now ### 5/5 — シンプルイズベスト *2025-06-21* アップルの純正アプリをずっと使っていましたが、アップデートでものすごく使いにくくなってしまったので探していました。 デザインもクラシックで気に入っています♪ ### 5/5 — Rakamlar çok büyüdü *2025-02-28, version 1.9.0* Severek kullanıyorum fakat son güncellemeden sonra rakamlar çok büyüdü ve küçülte bileceğim bir ayar yeri bulamadım --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
