Hoplavox is an app of educational mini-games for children aged 3 to 10, in French and English. The child plays with their voice: they count, name, repeat, sing or blow, and the game moves on. A friendly frog guides every game, and everything works offline.
From 3 to 10 years old, in three stages: Tadpole from 3 to 5, Froglet from 5 to 7 and Frog from 7 to 10. The stage offered first follows the age you set, and your child can pick another one on the game map.
The home page has four short steps: who is playing (a number, never a name), the age of the child, the game language, then start. The app asks for the microphone the first time a game needs it. Then you can hand over the device.
No. There is no account, no email and no sign-up. You install the app and play.
Yes. Each child is a number, from Child 1 to Child 8, with their own age, stars and results. Brothers, sisters and cousins can each have their own progress on one phone or tablet.
No. Tadpoles play only with sounds and pictures: the frog gives every instruction out loud. Short written hints appear in the frog's bubble for older children and for the parent, but they are never needed to play.
Twelve: Ball jump, The walking man, Tug of war, The parrot, The Do-Re-Mi door, The big breath, Around the world, Syllables, Missing word stories, Balance, Patterns and the Sliding puzzle. Each one has three stages and three levels per stage. A thirteenth game, Words of the world, is planned for later.
At the end of a game, the child gets three stars from 80 % of answers right the first time, two stars from 50 %, and one star otherwise. Level 1 is always open, and two stars on a level open the next one.
Yes. In the last setup step, a parent can switch on "Unlock all levels". It is useful for an older child, or to try a game before handing it over.
They are never stuck. After two misses, the frog gives the answer and the child repeats it. After four misses or three silences, the game moves on anyway. The only exception is the tug of war, where a miss loses the turn right away, like in a real game.
Yes, in the tug of war. Two players share the same screen and answer in turn, each with their own questions, so their voices never mix. The frog announces whose turn it is. Playing on two devices is planned for later.
A few minutes. Games are short on purpose: enough to learn something and feel proud, not enough to tire a young child.
The app asks for confirmation first, with a big button to stay. If the phone rings or the app leaves the screen, the game pauses, every sound stops, and it picks up where it was when you come back.
Because the voice is how the child plays. The microphone hears the answer, the note sung or the breath, and the game reacts. Without it, the voice games cannot work.
No. The sound is understood on the device, in real time, and is never written to a file, kept or sent anywhere. Only the result is saved for the parent dashboard: the expected answer and the words the engine understood, as text.
No. It opens only while a game waits for an answer, closes while the frog speaks, and is released as soon as the game ends or the app leaves the screen.
It tries hard. For Tadpoles, the checking is tolerant: each expected word has a list of variants and close pronunciations, and the engine is told which words to expect. If a word is still not understood, the frog helps after two tries, and the child is never stuck.
The app filters the sound and only reacts to a real voice: a door, a knock or a noise without a voice is ignored. Still, a calm room works best. With two players, the tug of war asks each child in turn so their voices do not mix.
Check that the microphone permission is allowed in the device settings, that nothing covers the microphone, and that the child speaks close enough to the device in a calm room. Make sure the game language matches the language your child speaks. If a specific word keeps failing, write to us with the game and the word: we improve the recognition from real cases.
Open the device settings, find Hoplavox in the list of apps, then allow the microphone. On iPhone and iPad: Settings, Hoplavox, Microphone. On Android: Settings, Apps, Hoplavox, Permissions, Microphone.
For the Do-Re-Mi door, the app measures the pitch of the voice and compares the note name in any octave, because children often sing higher. For the big breath and the balance game, only a real breath counts: a loud sound without a note, held for a moment. A voice, a short noise or the room never count, and the balloon never pops.
None leaves the device. On the device, the app keeps the settings, a label for each child such as "Child 3 · 4 years", the stars, and the results of each answer for the parent dashboard. No name, no photo, no location, no contacts, no audio.
No. Games, voices and speech recognition are all inside the app. On Android, the released app does not even ask for internet access. You only need a connection to download it from the store.
There is no advertising of any kind, and no purchase is ever offered to the child inside the games.
No. The app has no analytics service, no advertising identifier and no third-party tracker. This website does not use any either.
The settings and the parent dashboard are protected by a parental gate, an adult check that young children cannot pass by chance.
Hoplavox is designed to meet COPPA in the United States, the GDPR in Europe and its rules for children, and the requirements of the Google Play Families program and of the Kids category of the App Store. Since no personal data leaves the device, there is nothing for us to collect or share.
In the parent dashboard, use the clear button: every result saved on the device is deleted. Uninstalling the app deletes everything. Since we never receive the data, we hold nothing about your child on our side.
Games are short, there are no notifications and no endless rewards. The screen stays on during play, but goes to sleep on its own after four minutes without activity, and the game pauses as soon as the app leaves the screen.
They are short and gentle, and the balloon finishes inflating on its own after a few tries. If a child feels dizzy, they should stop and breathe normally. For the balance game, play seated and hold the device firmly.
Counting and the names of numbers up to 100, vocabulary (colors, shapes, objects, animals, fruits, vehicles, the body, days and months), pronunciation, music notes, breath control, geography, splitting words into syllables, listening comprehension, logic and planning.
The content follows what children of each age learn at home and in preschool and primary school: numbers, everyday vocabulary, syllables, the world. Syllable counts accept the two ways schools count them, for example "pomme" in one or two syllables in French.
When the child gets it right the first time on two different days. Learning that lasts is learning that comes back.
Some games, like syllables, repeating words and breath control, practise skills that speech therapists also work on, and many families enjoy them for that. But Hoplavox is a game, not a medical or therapy tool. If you have a concern about your child's speech, please talk to a professional.
Yes, with a device per small group. Each child can have a number, and the dashboard shows their progress. Since there are no accounts and no data leaving the device, there is nothing to set up with the school. Write to us if you use it in a classroom: we love to hear how.
For each child, each language, each game and each day: the share of answers right the first time, the response time, the silences, curves over time, what is learned, what to practise next, and every single answer.
Yes, as a JSON file you can keep or share, for example with a teacher. Nothing is sent automatically: you decide what to do with it.
A small bar at the bottom of the game screen shows what the microphone hears and what was expected. It helps a parent understand why an answer was accepted or not. You can switch it off in the settings.
Yes. Tolerant checking is meant for Tadpoles and can be switched on or off by a parent in the setup steps.
Choose the child again on the home page and set the new age, from 3 to 10. On the game map, your child can also pick another stage at any time.
French and English, for both the frog's voice and the speech recognition. The English voice is British.
Yes. The app language (menus and buttons) follows the device by default, and the game language (the frog's voice and the listening) is chosen in the setup. An English-speaking parent can keep the menus in English while the child plays in French, and the reverse.
Yes. Results are kept per language, so you can follow progress in French and in English separately. Repeating words with the parrot and naming things in the walking man are good ways to practise a second language.
The Words of the world game will bring hello, thank you and other words in 10 to 20 languages, always recorded by real people who speak each language. Full games in other languages are not planned yet.
Android phones and tablets, iPhone and iPad. On phones the app stays upright; on tablets it uses the landscape view. The minimum system version is shown on the store page.
Not for now. The offline speech recognition needs the app installed on the device, so Hoplavox is offered on phones and tablets.
Because it carries its own speech recognition models, in French and in English, so it can understand your child without the internet. The exact size is shown on the store page.
No more than a calm game. The frog redraws slowly at rest, nothing animates for nothing, the microphone is closed outside answers, and everything stops when the app leaves the screen.
Yes, once installed, Hoplavox works fully offline, in airplane mode too. A quiet spot helps the microphone.
First, close the app fully and open it again, and check the microphone permission. If the problem is still there, write to hello@hoplavox.com with your device model, its system version, the game, the stage and the level. Please do not send recordings of your child.
Use the download button on this site, or scan the QR code with your phone. The link game.hoplavox.com opens the right store for your device: Google Play on Android, the App Store on iPhone and iPad.
The price is always shown on the store page before you download. Whatever it is, Hoplavox has no ads, and no purchase is ever offered to the child inside the games. Payments and refunds go through Google Play or the App Store, under their own rules.
Yes. Planned next: the tug of war on two devices, the Words of the world game, and two more thinking games, tic-tac-toe against the frog and the lily pad path. Updates come through the store, like any app.
Not for now, because the data stays on the device. A family backup between devices may come later; if it does, it will be off by default and turned on only by a parent.
Hoplavox is created by Georges Byona, through the LosingTek studio (losingtek.com), which designs and builds the app.
It joins "hopla !", the cry of joy of the frog when a child gets it right, and "vox", the Latin word for voice.
The frog's lines were produced with a professional voice tool, then checked one by one by the speech engine and processed by hand for a calm, even volume. The music notes and interface sounds are synthesized without AI. The future Words of the world will be recorded by real native speakers.
Write to hello@hoplavox.com. Many improvements to the listening come from real cases reported by parents.
