HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (23 new ratings a month on average since launch): about $100 a month per new rating a month. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★Oct 14, 2026

So far enjoying the app's actual functions but the AI slop writing is really jarring and a big turn-off that makes me feel annoyed and slightly infantilized. It's not a lot of text, really wish they would replace it with something human-authored.

★★★★★Oct 9, 2026

Strong LLM vibes in the design, the prose, the features. I understand the devs have to make money, but be aware that all the interesting Duolingo-esque personal trainer elements are behind a paywall. Unless you're willing to shell out 10 bucks a month all you're getting out of this app is a bunch of links to YouTube videos and some voice analysis tools that you can find in a dozen other places.

★★★★★Oct 8, 2026

misleading. could not use any features without paying.

★★★★★Oct 4, 2026

If you don't offer masculinization yet, why put it in your app description? Nowhere does it say COMING SOON or whatever. I feel like I've been catfished.

★★★★★Oct 2, 2026

Ive just completed my first day using it. So far I like how the lessons are planned out and the exercises feel helpful but not intimidating. One thing I would like to see is when adjusting your voice goal, to be able to use a recorded voice clip and see how that goal changes how your voice sounds while you adjust it. There is an option in the studio to do this, but it doesn't seem like it changes the goal

Store description

Your voice can change. The hard part is knowing whether it is working. Juni is a voice training app for voice feminization and voice masculinization. It listens while you practise, shows you your pitch, resonance and weight live, and writes next week's plan from what it actually heard. TEN MINUTES A DAY Each day is one short lesson: warm up, learn one thing, practise it, done. No endless exercise menus to assemble yourself. You show up, Juni decides what today is for. A COACH THAT KNOWS YOUR VOICE Every week you read the same short passage, and Juni compares it with every week before. You get a report in plain words, a before and after you can hear, and next week's plan built from your voice, not a generic course. SEE WHAT YOU CANNOT HEAR YET The Studio is a set of live instruments: pitch, resonance, weight, melody, a spectrogram, a recorder. Early on your ear cannot tell what changed. The meters can, and that is what keeps you going. EVERY VIDEO WORTH WATCHING Learn collects the community's most trusted free lessons, in order, with notes on what to take from each. Linked and credited, never copied. IT NEVER LEAVES YOUR PHONE No account, no sign-up, no analytics. Your recordings and measurements stay on your device. The only thing that ever leaves it is the receipt Google issues if you subscribe. TRY IT FREE The Studio instruments, your voice report, and every video and reading in Learn are free. Juni Plus opens your daily practice, the weekly coach, every exercise and three more Studio tools, with a 3 day free trial on the yearly plan. Whether you are trans, nonbinary, or simply want a voice that feels like yours, Juni meets you where you are and shows you what is changing.
