Trans voice training for iPhone
See your voice. Practice on your own terms.
Resona shows your pitch and resonance in real time, guides you through a structured 12-week path for voice feminization or masculinization, and keeps voice analysis on your iPhone.
Free to start · iPhone with iOS 17 or later · No account needed
Analysis on your iPhone
Your voice is measured on the device. No account, no ads and no third-party trackers.
Pay once, only if you want more
Live measurement and Week 1 are free. Pro is a single purchase, not a subscription.
Describes sound, not people
No gender scores and no verdicts. You choose the targets and the direction.
Vocal care built in
Warm-ups, rest nudges and gentle limits help you practice without pushing.
See your voice
Live feedback on the parts of your voice you can learn to shape
Pitch is only part of the picture. Resona also follows resonance — how the space above your vocal folds colors the sound — along with clarity, vocal weight, range and melody.
Real-time pitch
A smooth pitch trace in hertz and note names, drawn against a target band you choose. A balance meter shows how much of the last 30 seconds sat below, in or above your band.
Resonance brightness
A 0 (dark) to 1 (bright) meter based on the shape of your vocal tract. Switching vowels alone barely moves it; your lips, larynx and tongue position do.
Clarity (CPP)
How strongly a repeating voice pattern shows in the signal. Useful for comparing the same passage under similar conditions — not a clinical score.
Vocal weight
A Lighter ↔ Fuller reading in the voice report, compared with your own earlier reports of the same passage.
Vocal range
Two gentle glides map your comfortable lowest and highest notes. Comfort is the boundary that matters.
Melody & intonation
Pitch movement in semitones shows how much your speech rises and falls. With Pro, the Intonation studio works on rises, falls and key-word peaks.
Numbers describe sound, not people. Voices overlap widely, and there is no single right sound.
Learn step by step
Two 12-week paths at a pace that suits you
Separate feminization and masculinization courses, each with 60 short lessons. Every lesson pairs a clear explanation with guided exercises, live feedback and a moment to reflect.
Feminization path
Pitch, brightness, melody and a lighter vocal weight — from gentle foundations to everyday conversation.
Masculinization path
Pitch without pressing, roomy resonance and a full, easy tone — built step by step into connected speech.
Custom goal
Set your own pitch and brightness bands. The lessons follow your bands, and you choose how much brightness, melody and weight fits you.
Three stages

Use your voice on your own terms
5 lessons a week · most take 10–14 minutes · a stage review every four weeks
Week 1 is free in every path: five complete lessons, with no time limit.
Repeat lessons, take rest days and choose your pace. Week numbers organize the learning; they aren't a deadline or a promise of results.
Practice with purpose
Tools for focused, everyday practice
Short guided drills, real-life lines and ten Practice lab tools help you take a skill from a single hum into the conversations you actually have.
Drill library
Focused exercises for breath, glides, pitch steps, resonance and ear training, tuned to your target bands. A starter set is free.
Practice lab: ten tools
Free: recording readiness, practice intervals, an everyday voice log and a lesson review queue. Pro: teleprompter, blind listening, recording loops, phrase ladders, recording collections and one-cue experiments.
Warm-up & cool-down
Guided 3-, 4- or 6-minute warm-ups with hums, lip trills and glides, plus a cool-down to ease your voice back after practice.
Everyday phrases & prompts
Real-life lines for phone calls, work, social situations and introductions, your own phrases, and conversation prompts to answer without a script.
Reading coach
Read your own texts with live feedback and an optional pace guide.
Pitch & resonance games
Match the note, follow a moving line, hold resonance in your band and light up the notes you reach in the range explorer.
Hear yourself change
Track progress against your own baseline
Your ears are the best judge. Resona keeps your recordings and your numbers side by side, so you can listen back and decide what helps.
Voice journal
Record entries with pitch and brightness snapshots, then compare then and now side by side. Free includes 3 recordings; Pro is unlimited.
Voice report
Read a passage or talk freely for a full snapshot: pitch distribution and range, resonance, pitch movement, clarity, vocal weight, pace and pauses.
Progress charts
Weekly trends measured from your baseline, a practice calendar and your daily voice use. No scores, no judgments. Free shows 7 days; Pro keeps everything.
Goal tracker & reports Pro
With Pro, follow your own number week by week, see journal trends and create a one-page PDF report to keep or share with a coach.
Private by design
Your voice stays yours
Privacy in Resona comes from how the app is built, not from a setting you have to find.
- Voice analysis happens on your iPhone. Recordings are kept in the app's private storage.
- No account, no advertising and no third-party trackers. Usage statistics are optional.
- Optional iCloud sync (Pro) uses your own private iCloud database, managed by Apple.
- Feedback is sent only when you choose to submit it. A recent diagnostics summary is included only if you turn it on.
- App lock, discreet notifications and a discreet app icon help keep your practice to yourself.
Vocal care first
Comfort is the boundary that matters
Good practice should feel easy. Resona builds rest and gentleness into the routine.
- A loudness bar outlines a comfortable speaking zone — guidance, not an alarm.
- A gentle rest nudge after the daily practice time you choose, plus rest days and a voice rest timer.
- Warm-ups, cool-downs, a breath pacer and a gentle recovery path with deliberately tiny exercises.
- Calm mode hides streak numbers and comparisons when numbers start to feel like pressure.
A training tool, not medical care
Resona doesn't diagnose or treat any condition. If you feel pain, strain or persistent hoarseness, stop and consider seeing an ENT doctor or a speech-language pathologist (SLP).

Does my voice leave my iPhone?
Voice analysis runs on your device. Recordings stay in the app's private storage unless you turn on iCloud sync (Pro), which uses your own private iCloud, or you choose to share a recording or attach audio to a feedback report. Resona has no account, ads or third-party trackers. Usage statistics are optional and never include your recordings or audio. Read the privacy policy.
Which languages does Resona support?
The app follows your iPhone's language. Its interface, course navigation and exercise instructions are available in English, Simplified Chinese, Traditional Chinese, Spanish and French. Lesson explanations and reading passages are in English. You can also choose a language just for Resona in the iOS Settings app, under Resona › Language.
Is Resona speech therapy or a medical device?
No. Resona is a training tool. It doesn't diagnose, treat or prevent any condition, and its readings aren't clinical measurements. You can use it alongside a voice coach or speech-language pathologist; with Pro, you can share a PDF progress report with them if you choose.
Which devices and iOS versions are supported?
Resona is an iPhone app and requires iOS 17 or later. Voice analysis runs on the device and doesn't need an internet connection; purchases, restoring purchases, iCloud sync and sending feedback do.
