SignalProof vs Nafnti

SignalProof is a tone generator for repeatable speaker, room, headphone, and sound meter checks. Generate controlled signals, follow practical workflows, and save the setup so you can run the same check again. Use it when random music, videos, and undocumented tone tools make results difficult to compare. WHAT YOU CAN GENERATE - 1 kHz and custom sine tones - Pink, white, and brown noise - Linear and logarithmic frequency sweeps - Left, right, or stereo output - Conservative dBFS level control - Timed or continuous playback BUILT FOR PRACTICAL AUDIO CHECKS SignalProof helps you: - Compare speaker channels with pink noise - Run quick sound meter sanity checks - Find room resonances with sweeps - Repeat window, door, and isolation checks - Save test-session notes and reference readings - Export a local PDF report for follow-up LOCAL-FIRST BY DESIGN Your sessions, notes, presets, and reports stay on your device. SignalProof requires no account and includes no ads, analytics SDK, cloud sync, or AI service. FREE CORE, OPTIONAL LIFETIME PRO SignalProof is free to download. The free experience includes the core tone, noise, and sweep generator, starter workflows, local test sessions, basic sharing, and one custom preset. An optional one-time, non-consumable SignalProof Pro purchase unlocks four advanced guided workflows, burst and intermittent playback patterns with configurable timing, and unlimited custom presets. SignalProof Pro is a lifetime unlock, not a subscription. The purchase price is shown in the app using your App Store storefront. SAFETY AND LIMITS SignalProof generates digital audio signals. It does not guarantee a specific acoustic dBSPL output from an iPhone speaker, Bluetooth speaker, or external system. Actual sound pressure depends on device volume, speaker hardware, distance, room conditions, and measurement setup. It is not a certified sound calibrator, medical hearing test, or lab-grade acoustic measurement tool. Start with low volume, raise levels gradually, and protect your hearing.
