### 4/5 — Title Name

*2024-06-16*

Please enable the option to name a formula by long pressing instead of just swiping

Thank you

### 2/5 — Trigonometriche Funktion

*2024-05-09*

Ansich gefällt mir die App. Leider funktionieren die Trigonometriche Funktionen wie sin, coş etc nicht richtig. Ergebnis ist immer 0. Ich habe es am IPhone 15 pro und Ipad pro eingegeben. Funktioniert bei beiden nicht Schade. Sonst wäre es 5 Sterne wert.

### 5/5 — Tolle Software 👍🏻

*2022-08-26*

Nutze die Software für wiederkehrende Berechnungen, bei welchen ich einzeln Parameter ändern muss/möchte. Verbesserung sehe ich noch in der fehlenden Möglichkeit mit Einheiten z.B €, kWh, m3 zu rechnen. Hier sollte der Entwickler bitte nochmals nachbessern.

**Developer response:** Herzlichen Dank für Ihre Unterstützung und Ihr Feedback!
Das ist ein toller Vorschlag, und ich werde versuchen, ihn zu verbessern.
Bis dahin empfehle ich Ihnen, die Einheiten direkt als Suffix an den Namen anzuhängen. Fügen Sie dem Namen z. B. das entsprechende "_€", "_kWh", "_m3" usw. hinzu. Auch bei komplexeren Einheitenumrechnungen kann eine neue Umrechnungsformel als Brücke zur endgültigen Formel hinzugefügt werden.

### 4/5 — 希望能支持更多运算

*2022-04-30*

希望能支持更多的诸如积分 累加 累成 矩阵 行列式的计算

### 4/5 — 拖动排列和运用

*2022-04-26*

大佬，㈠，能不能增加拖动排列计算框。全部竖着排列，浪费空间。㈡，可不可以增加引用计算框的结果。像有数计算器那样。谢谢。
