Hear how you really sound. Fenno is a private voice mirror. Talk for a minute โ about your day, a meeting you just had, or a talk you're rehearsing โ and Fenno shows you how you actually spoke: your pace, your pauses, your filler words, your energy. Then it helps you notice how those patterns change over time. No forms. No mood emojis. You just talk. Analysis runs on your iPhone. Fenno never uploads your recordings โ no cloud processing, no accounts, no ads, no one reading your transcripts. โ WHAT FENNO MEASURES โ โข Speaking pace โ words per minute, and how steady it is โข Filler words โ the "um"s, "like"s and "you know"s you didn't notice โข Pauses โ how often and how long you stop โข Energy & pitch โ how loud and how varied your voice was โข Voice & Words โ your tone and your words, side by side โข Your normal โ after a few recordings, Fenno compares you with yourself, not with strangers โข Weekly Mirror โ a short look back at your week If a recording doesn't contain enough clear speech, Fenno tells you so instead of guessing. โ WHY PEOPLE USE FENNO โ โข A 60-second voice journal that's easier than writing โข Rehearsing a presentation, interview or hard conversation โข Cutting filler words and slowing down when nervous โข Noticing how their voice changes across days, places and people โ BUILT FOR PRIVACY โ Recordings are stored on your device and protected by iOS encryption. Transcription and analysis happen on-device. You can delete a single recording or everything, anytime. Your voice is not training data. โ FENNO PRO โ Free includes two recordings per day and weekly summaries. Fenno Pro unlocks unlimited recordings, goal tracking, Energy & People lenses (beta), Voice & Words, two-speaker split (beta), smart reminders and detailed weekly reports. โข Monthly: $4.99 (3-day free trial) โข Yearly: $29.99 (7-day free trial, save ~50%) โข Lifetime: $79.99 (one-time) Subscriptions auto-renew unless canceled at least 24 hours before the end of the current period.
