Texas Instruments, the No. 1 recommended brand of graphing calculators in the U.S., has optimized its most powerful Computer Algebra System (CAS) math engine for an all-in-one iPad app that makes teaching and learning math more engaging, meaningful and … fun! ONE CAS APP. ALL THE MATH. Open the door to math mastery with the first-in-class iPad CAS app that delivers comprehensive graphing, data entry and analysis, statistical modeling and calculating functionality. Solve equations with algebraic precision, factor and expand variable expressions, complete the square, find antiderivatives, compute limits, find exact solutions in irrational form and more. Make math more meaningful by importing images from the iPad camera or photo library and overlaying graphs and equations on them to illustrate abstract math principles in the real world.* Visualize crucial connections by observing how equations change — in real time, on one screen — when you touch, grab and interact with shapes, graphs and objects on the screen. Graph functions, inequalities, implicit functions, conic sections, scatter plots, statistical plots and regression models, 3D graphs, parametric, polar and differential equations. Enter equations in proper math notation so math symbols and formulas on the screen are identical to those in text books and on the board. Deepen understanding by exploring hundreds of free activities for Pre-Algebra, Algebra, Geometry, Calculus, Statistics, Pre-Calculus and more from the online Math Nspired resource center. Create and store work on your iPad, and share it using your Email or Dropbox account. A COMPLETE LEARNING RESOURCE TI Education Technology is committed to success in mathematics by providing advanced learning tools that have been designed in collaboration with leading educators and researchers. TI provides world-class professional development for teachers, as well as free activities and curriculum content.

This is a math equation editor which could export the result as picture, LaTeX, MathML, UnicodeMath(Word). Include variables, binary operators, arrows, relations, brackets, underline, overline, accents, fraction, radical, large operator... Just download and have a try. ----- 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 8. Help Document ----- 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.

Verdict

The call

The clearest difference is price: xFormula at Free against TI's $29.99. xFormula also leads on update cadence (every 3 weeks vs every 6 months) and review sentiment (84% vs 65%). TI's advantage is rating (4.6 vs 3.9) and in-app purchases (none vs 4). On ads and device support there is nothing between them.

xFormula is free to download; TI costs $29.99 up front. xFormula sells 4 in-app purchases, starting at $1.99 per month. TI asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

TI holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: TI has 406 ratings behind it against 55, so its average is the more settled of the two. Written reviews complicate that: 65% of TI's written reviews are positive against 84% of xFormula's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TI ships an update every 6 months, xFormula every 3 weeks. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
