Vielen Dank für deine 5 Sterne! Freundliche Grüße ### 2/5 — Платно *2024-02-03* Почему платно???? **Developer response:** Здравствуйте, 3538ученик7б! Приложение бесплатное. Реклама удалена, а возможность покупки больше недоступна. С уважением ### 5/5 — Sehr gut *2023-01-04* Sehr gut **Developer response:** Vielen Dank! ### 5/5 — Funktioniert Super! *2021-02-09* Ich habe es jetzt bei einer einzelnen Aufgabe ausprobiert und muss sagen es funktioniert perfekt. Jedoch muss man beachten dass man wenn man die Formel eingetippt hat, auch auf den Bestätigungshacken drücken muss und nicht direkt auf Ergebniss. **Developer response:** Hallo! Vielen Dank für das positive Feedback und den Hinweis. Wir werden nach Lösungen suchen, dass wir unser UI in Zukunft noch intuitiver gestalten werden. ### 1/5 — Probleme.... *2020-09-16* Hallo, die App wirkt auf dem Ersten Blick ja echt super, nur auf meinem Handy (IPhone 11) funktionieren nur die Zahlen, keine Buchstaben, ist das richtig? Ich würde ja glatt die Pro Version kaufen aber ohne Buchstaben bringt mich das nicht weiter.... **Developer response:** Hallo, vielen Dank für Ihre Rückmeldung. In unserem Testing konnten wir das Problem leider nicht nachstellen. In der App sind die Buchstaben fest definiert. Links wird ein "x" und rechts ein "y" hinzugefügt, wenn Sie auf die Taste "x/y" klicken. Diese Möglichkeit ist in allen 3 Rechenoperationen (+; -; +-) gegeben. Um eine mögliche Verwechslung der Funktionen vorzubeugen: Die "/" Taste ermöglicht die Rechnung mit Brüchen. Um ein Beispiel zu sehen, wo alle Möglichkeiten dieser App demonstriert werden, klicken Sie bitte links oben auf die 3 Striche, so dass das Menü erscheint. Dort ist unter "Verlauf" ein Beispiel vorgegeben, wo ein Buchstabe, ein Bruch und eine negative Zahl enthalten sind. Da Sie wahrscheinlich schon mehrere Rechnungen vorgenommen haben, könnte das Beispiel weiter heruntergerutscht sein. Freundliche Grüße ### 1/5 — Dreck *2020-04-29* Dreck **Developer response:** Hallo! Bei Dreck musst du putzen! Schade, dass dir diese App nicht zusagt. Bei Vorschlägen, Wünschen oder Anregungen schreibe uns doch gern an dev@gslstudios.com. Freundliche Grüße ### 5/5 — Besser ist das *2019-11-18* Pipipi **Developer response:** Pipi! Vielen Dank für die 5 Sterne! Freundliche Grüße ### 1/5 — Terrible *2018-05-01* Terrible terrible **Developer response:** Dear customer, so far we did not receive any described problems or negative feedback. It would be a pleasure to improve the content by your user impression. We would like to know what exactly is "Terrible terrible" at this app. This app totally fits into German standards and the way how this topic is tought here. Maybe some misunderstandings or mismatching happened.

By the way - I run many apps with different math topics. If you like this one: Check them out as well! I always do my best to keep a high standard on my apps. If something does not meet the expectations, do not hesitate to contact me. ### 3.1.3 — 2026-06-06 There were some major fixes and adjustments for a more stable behaviour of the solution storage and loading. Therefore some database changes were made in the background. There are no performance losses and the functionality does not change. The background tasks are only done once within milliseconds. Following behaviour may occur (only temporary): - stored calculations have to be tapped twice to load fully - the order of the stored solutions may change If there are some losses of solutions do not hesitate to contact me and tell me the number of lost solutions + affected app. I will find a solution for this.
