Functions:

1. Mathematical formula editing.

2. Import & Export
- LaTeX (Pages, Keynote)
- MathML (Pages, Keynote)
- UnicodeMath (Word)
- Image
- SVG: If the .svg file is exported by xFormula, then it could be imported and edit again.

3. Image recognition 
- Setup large model API to recognize the math formula in the image.
- The recognition of mathematical formulas in large models is getting better and better, but due to the large number of LaTeX commands for mathematical formulas, there may be some situations where the same symbol is different for different commands. xFormula cannot support all LaTeX commands yet, so there may be some exceptions. However, we will continue to optimize and be compatible with more commands in future versions

4. 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

5. 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.

6. 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.

7. Keyboard Extension
- Could be directly used in the form of a keyboard in other text editing software
- Due to the system's restrictions on keyboard Extension, there may be some abnormal situations. After installing the keyboard, if it cannot appear in the keyboard list, please restart the device and try again
- Although currently compatible with iOS 15, it is recommended to use new devices as old devices may experience loading failures due to memory limitations and other issues

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. If you plan to use this software for a long time and consider upgrading more features in the future, it is recommended to purchase the Professional Edition.

### 5/5 — Honestly the only good formula app I can find

*2026-08-19*

Really intuitive to use and perfect for taking notes. Just don’t try highlighting things that don’t make sense to highlight.

### 2/5 — Not Free

*2025-07-12*

This app is free to download but if you actually want to use it, you have to pay a minimum of a $7 subscription, utterly useless otherwise. In the “free” version you can only type less than 10 characters. Do better.

### 4/5 — 使いやすい！

*2025-04-28*

勉強にもなります
でも有料とかあるから
☆4にしておきます。

### 5/5 — Exelent

*2025-03-01*

Honest app ever.

**Developer response:** Thank you for your appreciation of xFormula! :-)

### 5/5 — Great! Needs minor tweaks.

*2025-02-25*

Can you please add the ability to hide/minimize the keyboard?

请允许隐藏或最小化键盘！

**Developer response:** This will be done in future versions. Thank you for your feedback!

### 1/5 — 환불받고싶어요

*2025-02-17*

실수로 잘못 결제했어요

**Developer response:** You could Google AppStore refunds, and there will be a detailed refund process. Both purchase and refund are handled by Apple.
AppStore 환불을 Google에서 확인할 수 있습니다. 자세한 환불 절차가 있을 것입니다.구매와 환불은 모두 Apple에서 처리합니다.

### 5/5 — Request for discount

*2025-01-30*

Please put a discount on your app :)
It would be great to have Pro features with 75% for example 🫠🫣

### 5/5 — Great! Needs minor tweaks.

*2024-10-03*

Can you please add the ability to hide/minimize the keyboard? Ability to draw geometric figures would take it to a next level!

### 3/5 — Boo to the “plans”

*2024-10-02*

I really liked this app and thought it was a good buy, and I guess it’s not my fault for not fully looking at each plan but why is it set up that you can only use u dear 10 characters for the $5 plan. For the $9 plan is it just the app and not the keyboard? That’s just wild to me because what math/scientific equation is under 10 characters?

**Developer response:** $5 & $9 plan have no characters limit. Only Experience mode has 10 characters limit. Maybe the In App Purchase Product Description is not clear, Thank you for your more suggestion about description. :-)

### 5/5 — I love this equation editor

*2024-09-25*

Helped me a lot! Much improved with the new export options!
