Functions:

1. Mathematical formula editing. Export format: LaTeX, Image.

2. Mathematical formula library:
- You can create several formula libraries at the same time, and each formula library can be exported and imported separately;
- Under each formula library, there can be many categories, and under each category, there can be many groups. Under each group, formulas can be created and edited
- Example 1: High School Mathematics Formula Library > Classification 1: Set, Classification 2: Geometry, Classification 3: Algebra
- Example 2: Junior High School Mathematics Formula Library>Classification 1: Rational Numbers, Classification 2: Trigonometric Functions, Classification 3: Geometry

3. Mathematical style:
- Due to font limitations, the mathematical formulas currently provided may have some pixel spacing flaws, and each style may also have several mathematical characters that are not supported. Please use them as appropriate.
- We will continue to optimize mathematical styles, which is what we are concerned about.

4. Custom keyboard:
-The frequency of mathematical symbols used varies at each stage, from elementary school, middle school, high school to university; The frequency of symbols used for sets, limits, matrices, functions, and each knowledge range is also different. So if you use it for a long time or frequently, it is strongly recommended to create a suitable input symbol keyboard for yourself, which is more efficient and saves more time than a universal keyboard.

Purchase:

1. This is a paid software and is provided for free download in the hope that users will know what features this software has and whether it is useful before purchasing.

2. As the payment methods for iOS and macOS were not unified when this software was first released, xFormula (iOS) and xFormula (macOS) need to be paid separately.
The advantage of separate payment is pricing splitting, which means that if you only have a mobile device and don't have a Mac, you can save on the purchase cost of the Mac. If merged, the pricing will also be the sum of the current two pricing.

3. Up to now, the software is provided with a buyout system, one-time purchase, lifetime use.
