Pukkala: Flatulence Analyzer

Acoustic Fart Detector

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Record, study and archive your flatulence. Tag with food notes, share with a sweetheart. Twelve features, six classes, one score out of 100. Mathematically precise. Pukkala is a social network for the body's most overlooked signal: a fart. Push to record. Get a score. Drop it on the feed. Every flatulence event runs through a real on-device DSP pipeline — twelve acoustic features extracted from the raw audio (duration, peak, RMS, spectral centroid, flatness, rolloff, dominant frequency, zero-crossing rate, and a 13-coefficient MFCC vector). Each gets classified into one of six deterministic classes — silent, squeaker, trumpet, wet, compound, classic — based on distance to centroid in feature space. No black-box model, no training data, no drift. Pure analysis. THE SCORE A single number from zero to one hundred. Four weighted terms: — Duration. Normalized event length, capped at five seconds. — Intensity. Peak amplitude and RMS energy, A-weighted. — Spectral richness. Centroid, rolloff, and the first three MFCCs. — Rarity. Cosine distance from the centroid of your last hundred events. Your score is benchmarked against your own history, not a global average. THE NETWORK Anonymous if you want, public if you don't. Either way, on the record. Follow people, react to events, build streaks, climb the daily Pukkala Index. Every event is a structured artifact you can share — score, classification, AI interpretation, and the full feature vector. PUKKALA PRO Same engine, sharpened. Current paid features are shown in the in-app paywall; experiments marked "Upcoming" are not sold as available today. — Unlimited recordings and full event history. — Original audio retention and WAV download. — Food-aware AI notes using your logged meals. — AI listening notes when enabled. — Sharper map precision, Pro badge, and club hosting. $3.99/month or $39.99 lifetime. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://pukkala.com/legal/privacy PRIVACY Saved recordings and acoustic features (numbers describing the sound) are uploaded for analysis, playback, and sharing. Free-tier audio expires after 30 days; Pro keeps saved audio long-term. Location is opt-in and fuzzed before it leaves your phone unless you choose Pro exact-pin sharing. We sell nothing. Pukkala is for entertainment and personal curiosity. The Pukkala Index, classifications, and AI interpretations are not medical or diagnostic information. Don't make health decisions based on what Pukkala tells you — talk to a doctor.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Fixes a bug where the analysis screen could hang after recording on a weak connection — your score now always comes through. Sharpens status-bar visibility on light screens, smooths the feed on first load, corrects the activity event count, and tidies a few smaller rough edges.
