PocketCAS is a graphing calculator for iPhone and iPad. It graphs your functions, finds derivatives and works with exact fractions and roots. Everything runs on your device, so it works without internet or an account. An in-app purchase unlocks PocketCAS Pro, with steps, integrals and the solver. Graphs - 2D plots of functions, implicit equations, polar and parametric curves and vector fields, two functions per plot. PocketCAS marks zeros, extrema and intersections. In full screen, tap a mark to read its coordinates. - 3D surfaces with soft light and shading. Drag to turn them, pinch to zoom. Derivatives - Under each function, a suggestion shows its derivative, already worked out, and a small plot sits beside the result. Tap one to add it to your document. - Exact derivatives of products, quotients, roots and chains, written the way your textbook writes them. Exact results - Arithmetic with exact fractions and roots, trigonometric, exponential and logarithmic functions. - Matrices: determinants, inverses and products. - Your own functions, with conditions and recursion. - Common units and physical constants. Reads like your textbook - Results look the way they do in a textbook: fractions, roots, powers and matrices. - A math keyboard with every function in reach, and a hint shows what goes between the brackets. Made for daily work - Documents keep your calculations and plots together, and iCloud syncs them between your devices. - Export and print plots, entries or whole documents (with a watermark). - Help built in: the function reference explains every function with examples, and tutorials get you started. Unlock PocketCAS Pro One purchase in the app unlocks everything in PocketCAS Pro, without a subscription: calculation steps that name the rule behind each step, integrals, limits, series and sums, equation and system solving, factoring and simplifying, eigenvalues, differential equations, scripts, plots with more than two functions, imports of documents and CSV data, larger matrices in the editor, exports without a watermark, and suggestions with zeros, extrema and integrals. Family Sharing is included, and Restore Purchases is in the main menu. Until you unlock it, the function reference marks the functions of Pro with a PRO badge. PocketCAS Pro is also sold as its own app; you need only one. Questions or ideas? Write to us at https://pocketcas.com/support.

Use this limit derivative calculator app to calculate derivative of a function perfectly. Differentiation involves the changing rate of a function with respect to a certain variable. Subject to a simple-to-use differentiation calculator to differentiate a function properly. Example: Suppose if a car is running at a particular velocity with respect to the time and suddenly it changes. This change is acceleration and acts as the derivative of the velocity function by means of time. Our online derivative finder immediately resolves such instant changes and displays results on your screen. Geometrical Interpretation Of Derivative: In geometry, the differentiation refers to the slope of a line. This particular line lies on the tangent of the curve. You can easily enter a function of the line in this derivatives calculator. How To Calculate Derivative Of Complex Functions: This d/dx calculator provides you with an edge of determining the variations in the complicated functions by means of no time. Infact, you can also calculate derivative step by step at any certain point with the help of the online derivatives calculator app. How calculus derivative calculator works? Enter the function in the menu bar Select the4 variable with respect to which you want to determine the derivative of the given function Select the number of repetitions upto level 5 Tap the calculate button Features Of Online Differential Calculator: User-Friendly Interface Advanced keyboard for entering trigonometric and logarithmic functions Available online as well as offline 100% Absolute Results Free Downloadable PDF File of final results with detailed steps involved Step-By-Step Calculations Easy to use So grab this free derivative calculator and determine the deviations of simpler or even complex functions immediately.

Verdict
The clearest difference is monetization model: PocketCAS at free against Derivative Calculator Solver's free with in-app purchases. PocketCAS also leads on rating (4.6 vs 4.3) and ratings volume (204 vs 12). Derivative Calculator Solver's advantage is iOS requirement (15.6 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PocketCAS sells 1 one-off in-app purchase and Derivative Calculator Solver sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
PocketCAS holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: PocketCAS has 204 ratings behind it against 12, so its average is the more settled of the two.
PocketCAS ships an update every 3 months, Derivative Calculator Solver every 7 months. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
