SymboCalc vs Ping_Pro

SymboCalc is a symbolic calculator that gives you exact answers, not just decimals. Factor a polynomial, solve an equation for a variable, differentiate, integrate, invert a matrix, then plot the result... all in one app, all on your device. EXACT BY DEFAULT Results stay exact: 1/3 is 1/3, not 0.3333. Radicals, fractions and complex numbers are kept symbolic and typeset as real mathematics, with stacked fractions, proper radicals and matrix brackets. Tap any answer to switch it to a decimal, and tap again to switch back. ALGEBRA Expand, factor, simplify, collect, partial fractions, proper fractions, common denominators, polynomial division and GCD, trigonometric expansion and collection. CALCULUS Derivatives to any order, indefinite and definite integrals, limits including one-sided limits and limits at infinity, Taylor series, summations and products in closed form, arc length, numeric derivatives and integrals, and differential equations with initial conditions. EQUATIONS Solve exactly or numerically, over the reals or the complex numbers. Systems of equations, polynomial roots, and a dedicated numeric solver where you fill in what you know and solve for the rest. MATRICES AND VECTORS Determinants, inverses, rank, RREF, eigenvalues and eigenvectors, characteristic polynomials, LU and QR, null space, dot and cross products — with symbolic entries, not just numbers. GRAPHING Functions, implicit equations, inequalities, parametric curves, polar curves, sequences, differential equations with slope fields, and rotatable 3D surfaces. Pan and pinch, trace, and find zeros, minima, maxima, inflection points, intersections, tangents and areas. Logarithmic axes and sliders for free parameters are built in. STATISTICS One- and two-variable statistics, ten regression models from linear to logistic and sinusoidal, and the normal, t, chi-square, F, binomial and Poisson distributions. MORE Unit conversion with dimensional analysis and physical constants. Base and bitwise arithmetic in hex and binary. Time-value-of-money and cash-flow functions. A programming language with loops and conditionals. Tables of values. Saved worksheets you can export as PDF. BUILT FOR TYPING MATHS One keypad, no modes. A strip of operations sits above it — solve, factor, expand, d/dx, integral — and the full function browser is one tap away, with an example you can run for every function. The letter keyboard is there when you need a name, and gone when you do not. PRIVATE BY DESIGN SymboCalc collects nothing and makes no network requests. There is no account, no tracking and no advertising. Your work stays on your device.

PingPro keeps your school day in view without digging through a PDF timetable between classes. Now and Next, at a glance Open PingPro to see your current class and what's coming up next — subject, teacher, room, and how much time is left — the moment you need it. A heads-up before every bell PingPro notifies you a few minutes before each class ends, so you're never caught packing up late. Choose your own lead time, from 1 to 30 minutes. Built for how real school schedules actually work Handles two-week rotating timetables (Week 1 / Week 2) automatically — or switch to single-week mode if your school doesn't rotate. Automatically shows the next school day's schedule after hours or on weekends, and understands breaks as real parts of the day, not just gaps. Import your timetable in seconds Scan a screenshot or PDF of your school portal timetable — PingPro reads it on your device and builds your schedule for you, with a chance to check it first. You can also import a CSV and export it back out any time. Right on your Home Screen Add the PingPro widget to your Home Screen for an always-visible look at what's now and what's next, with a live countdown, no need to even open the app. Light and Dark Follow your device's appearance, or choose Light or Dark inside the app. Also on your Mac The same Now/Next view lives quietly in your Mac's menu bar, so your schedule follows you between devices. Private by design Your timetable never leaves your device. Every notification is scheduled locally — there's no account, no server, no internet connection required. Requirements: iOS 17 or later.
