Es gibt sie doch. Es steht in der App man soll ein Video ansehen um die volle Funktionalität freizuschalten. Nach dem Video kommt noch die Anzeige zu dem Video und die geht nicht mehr weg. ### 1/5 — Frozen in time. *2025-08-04, version 1.7.4* The currency exchange rates are frozen in the past, refreshing multiple times doesn’t do anything. ### 5/5 — 挺好 *2025-02-09, version 1.7.4* 用着不错 ### 5/5 — 好用，简洁无广 *2025-01-20, version 1.7.4* 还有圣诞皮肤，很可爱。 功能也特别全面 ### 5/5 — great *2024-07-19, version 1.7.4* i can do everything with this app, it's perfect to my use ### 5/5 — A melhor calculadora *2024-03-24, version 1.7.4* Recomendo a todos! ### 1/5 — Paling jelek! Very very BAD! Terrible! *2024-03-09, version 1.7.4* Aplikasi yang mengerikan! Saya sudah muak dengan tarian panjang yang melibatkan rolet, sampai-sampai saya kehilangan keinginan untuk mencoba dan menghapusnya. Aplikasi menjijikkan. Siapa yang membutuhkannya dengan berlangganan? Dan tidak ada Indonesia dan rusia bahasa! ### 5/5 — 超好用很多功能👌 *2024-01-15, version 1.7.4* 雖然每次點進去都會跳廣告頁面 但是只少可以秒按掉不用等秒數 最常拿來換算幣值 ### 1/5 — Calculator is a total scam why? *2023-12-16* Too many Ads and scam you on getting another of their apps. Every time you press a number or a function, ads pops up. This is ridiculous. ### 1/5 — it’s only a Game Ad.. not a calculator *2023-12-14, version 1.7.4* Just looking for a scientific calculator app with no ads … all u get with this is a silly game ## Frequently asked questions about FP Scientific&Basic Calculator ### What does FP Scientific&Basic Calculator do?
