Description by Anas Abubakar Written by the developer, not by AppBrain. Click to read.

Design RC, RL, and RLC filters (2nd–7th order) with Butterworth & Chebyshev alignments, passive crossovers, RLC band-pass/reject, and Twin-T notch—enter specs to instantly get component values and quick Bode insights in a clean, offline-friendly, dark-mode UI for lab, classroom, and audio/embedded work.

What you can design:
-RC & RL filters: low-pass / high-pass, 2nd–7th order
-RLC filters: band-pass & band-reject (notch)
-Butterworth: maximally flat magnitude
-Chebyshev: ripple-tuned sharpness
-Twin-T notch: precise mains or tone suppression
-Passive crossovers: 2-way/3-way starter calculations

Built for engineers, hobbyist and students, it turns specs into trustworthy parts fast—so you can prototype smarter, learn by tweaking, and move from idea to BOM with confidence.
