Now I get very annoying ads. ### 4/5 — HV *2026-08-01, version 1.6* Works great with many options ### 4/5 — Good *2026-04-22, version 1.6* Has adds- but amazing otherwise ### 2/5 — Not a fan *2026-03-30, version 1.6* Great calculator. Hate the ads and the model to turn them off temporarily. Just let me pay for it for NO ADS! ### 2/5 — Ads *2025-12-06, version 1.5.6* Was great at the beginning. I bought it so shouldn’t be any ads. Even so they use to stay in a top ribbon but now they are intrusive and can make it unusable unless your in airplane mode. ### 4/5 — Great design, but missing standard scientific buttons *2025-09-15, version 1.5.6* While I like the overall design of the calculator, it seems to be missing 3, of what seem to be standard, scientific calculator buttons, the cubed root and the custom root function button, as well as a 1/x button. I find it odd for such a capable and stylish calculator app (I hate Apple’s bland calculator design) to not include them when most other apps do. ### 5/5 — Great Calc I ever had *2025-07-24, version 1.5.6* This app is fantastic because it not only displays “0,” but also “00” and “000.” This feature is particularly useful when using a calculator as an accounting tool in a country with high inflation rates. Thank you. ### 5/5 — One Calc *2025-07-16, version 1.5.6* Very easy to use ### 5/5 — Inflation rate *2025-06-21, version 1.5.5* Please add SIP, SWP and inflation rate in finance section of it so that we can find the rupee value in future Rest all is very nice ### 5/5 — Great *2025-06-02, version 1.5.5* Easy to use for us old seniors. ### 5/5 — Excellent app! Many handy extras! *2025-03-27, version 1.5.5* Does everything one would need/expect from a regular calculator + many other calculation tools to use for work or just play around with…Excellent app that I would highly recommend! ## Most critical reviews (10 lowest-rated) ### 1/5 — Feedback *2026-07-25, version 1.6* The calculator is great but I HATE the gambling and betting adds! Terrible and difficult to refuse or reject! They are the worst and must be removed! Imagine a child using this app and being tempted to gamble!! Grrr ### 1/5 — User *2026-06-22, version 1.6* Got a fake screenshot that filled my screen with fake your phone is infected that had a click this link which leads to scammers trying to steal passwords for money etc ### 1/5 — 有广告 *2026-04-23, version 1.6* 充钱解锁无广告 ### 1/5 — Failed to sleep *2026-01-12, version 1.6* Left app and it failed to sleep, and ran the iPad completely flat. Removing it immediately.👎 ### 1/5 — Adds *2025-12-21, version 1.5.6* To many adds came up virus warnings Very annoying. ### 1/5 — Beware Virus Warning *2025-12-18, version 1.5.6* This app had a scam advertisement that told me I had 17 viruses on my iPhone! It’s one thing to have annoying adverts, but it is another to try and scam people into buying virus removal software by telling them they already have viruses. Needless to say I’ve deleted the app and will never use it again! ### 1/5 — Advertises Scams *2025-10-28, version 1.5.6* Do not download. It uses ads that direct scam websites. ### 1/5 — Pub *2025-09-28, version 1.5.6* Aléa us pub Even of you Pau ### 1/5 — Has ads. *2025-04-02, version 1.5.5* There are ads that come in between the usage.
