Fryda vs SymboliX

Fryda is a place for all your products' important information. Receipts, warranty and more - that otherwise would be scattered around in your pockets, wallet, home and email inbox. Now you can easily add products after your done shopping and store them in one digital place where you know you'll always have them – whenever and wherever. No more are the days of searching for boring papers or info you wish you had about your valuable products. When you want to resell and pass on info, make an insurance claim, repair products, buy accessories, recycle parts or return a product - any info you would need, can be found a button press away in the Fryda app. We're constantly updating Fryda, with new features and more connected businesses, so you can have a worry-free and sustainable post-shopping experience. Welcome to a 'frydfull' life! HOW IT STARTED We were tired of having our receipts spread out everywhere, nowhere to be found when you actually needed them. After playing with ideas to solve this we realised we often wanted more information from our receipts and the stuff we own – like warranty, product info and even more. We want to connect people with the places that we buy our products from – that offer reparations, spare parts, accessories and other direct help specific to you and your product. In this way we can also create a more sustainable and conscious product loop. To solve this we are creating interactive receipts – or "digital product cards" as we call them – to keep track of all of our stuff as easily as possible. That's where the idea of Fryda started – a place dedicated to your valuable products and all important information connected to them. During ownership, recycling or resale. Fryda – A worry-free post-shopping experience.

SymboliX — the symbolic calculator that explains itself Type a problem and get an exact symbolic answer, typeset like a textbook. Every result is a card: differentiate it, integrate it, plot it, or open the step-by-step solution with one tap. COMPUTE • Derivatives, indefinite and definite integrals, limits, series • Equations and systems, with numeric roots when there is no closed form • Simplify, expand, factor (and prime-factorize integers) • Matrices: determinant, inverse, eigenvalues • Differential equations (desolve) SEE IT • Results that are functions plot themselves: definite integrals show their area, solved equations mark their roots • Full-screen graphing with pan, pinch-to-zoom and live updates as you type PROGRAM • An Xcas-style language: functions, local variables, for / while / repeat loops, recursion, lists, print output • Example programs: Fibonacci, primes, Newton's method, the Collatz sequence, matrices • Variables carry across cards; reset them any time STEPS AND THE AI TUTOR • Step-by-step solutions are free for everyone • Want to know why each step works? Unlock the AI tutor once: it explains the reasoning, the common traps and how to check the answer (100 walkthroughs a month; a one-time purchase, not a subscription) ALSO • Notebooks to keep your work • Computing, plotting and programming work offline and are free forever • English and Simplified Chinese
