It is the first app I’ve ever built, and at the risk of sounding cheesy - it still holds a special place in my heart. Even though it was never a significant moneymaker, I’ve kept it updated throughout the years. And I’m happy to say that it has attained over 95.000 downloads to date. If you enjoy using the app, please consider buying the full version. Thank you. - Lukas Petr, author of Quadratic Master

No tricks, no guessing. Factor quadratic equations using a parametric method – fully and clearly understandable. HOW IT WORKS Enter the coefficients a, b and c of the equation ax² + bx + c. The factorization is derived step by step in a systematic way. You can share results at any time. YOUR PERSONAL DATA We don’t need it. Only anonymized data is collected, for example: - which features are used - how many solutions are generated This helps us improve. No conclusions can be drawn about you. COSTS Everything can be used for free. 24/7 access to your solutions. All solution steps are always shown completely. If you use the app more intensively, various purchase options are available. EXTRAS - Feedback for incorrect inputs - Manage your own solutions - Introduction to the app CONTACT Questions and feedback via Discord or directly in the app review.

Verdict
The clearest difference is rating: Quadratic Master at 4.6 against Parametric Factorization's 2.9. Quadratic Master also leads on review sentiment (74% vs 40%) and ratings volume (333 vs 8). Parametric Factorization's advantage is update cadence (fortnightly vs every 5 months) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
