Filtroscope permet de tracer des circuits de filtres électroniques et d'en obtenir automatiquement : • la fonction de transfert (expression littérale), • le diagramme de Bode (gain et phase), • la réponse en amplitude, • une visualisation à l'oscilloscope des signaux d'entrée et de sortie. Idéal pour les étudiants en CPGE et en Licence, et pour les enseignants de physique. 100 % hors-ligne, sans publicité, sans collecte de données : tous les calculs s'effectuent sur votre appareil.

Verdict
The clearest difference is in-app purchases: Filtroscope at none against Impedance Calculators's 1. Filtroscope also leads on ads (none vs shown) and update cadence (daily vs every 21 months). On price, device support and iOS requirement there is nothing between them.
