## What is Circular Cone PRO?

The best app to calculate all quantities of a circular cone. You must enter some quantities like the radius and a height. The algorithm searches the formulas of the missing quantities, shows them and calculates the results.

The length of the decimal place can be changed. The algorithm shows when rounding or wrong values lead to an opposition.

Decimals and fractions are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared.

[ Contents ]
- all important quantities for the circular cone
- formulas for all important quantities of a circular cone
- infographic to illustrate the topic
- search bar to find the desired quantity
- history function to save the input
- detailed solution
- positive numbers, decimals and fractions are supported
- no ads!

[ Usage ]
- there are fields for entering values using a special keyboard
- press the check mark button at the bottom right to start the calculation
- if values are missing, all fields will be marked orange
- if the values are wrong (e.g. negative lengths), the affected field will be highlighted red
- if a value is no number, it is highlighted in red
- the entries in the history can be deleted or sorted
- if you select an entry in the history, it will be automatically loaded for the calculation
- the whole history can be deleted by pressing a button
- solutions can be shared

[ Math conditions ]
- each value must be greater than zero
- angle α, γ must be less than 90°
- angle ζ must be less than 180°
- angle Ф must be less than 360°


## Version history (last 5 releases)

### 2.2.3 — 2026-08-14

The latest release 'Least common multiple' is linked in the menu section now.

Minor performance and UI fixes.

### 2.2.2 — 2026-08-04

- the status bar on top is integrated into the current app design
- the app flow was improved (pop-up information was balanced)

### 2.2.1 — 2026-07-17

Maintenance update. Improving performance.

### 2.2.0 — 2026-06-19

Bringing all apps to the same security standard. Critical storage behaviour for solutions has been fixed.

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.

### 2.1.10 — 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.

Kind regards, Alex (the Dev)
