Oggy turns your iPhone or iPad into a simple speech board. Tap a button, "I want water," "All done," "I love you" and Oggy says it out loud. That's the whole idea, and it works in seconds. Or build out entire sentences by tapping word buttons. Two modes for two separate needs. It's built for parents, caregivers, and speech-language pathologists who want something fast to set up, easy to learn, and respectful of privacy — without paying the $200+ that traditional AAC apps charge. BUILD A BOARD YOUR WAY Add up to 12 buttons in the free tier — unlock unlimited buttons and a pre-built core board with a $9.99/year subscription. Each button speaks whatever phrase you choose, with the symbol of your choice: a photo from your library, a quick camera shot, or any emoji from your keyboard. Pick a color, arrange the grid the way that makes sense, and rearrange anytime with a long-press and drag. VOICES THAT FIT YOUR FAMILY Choose from the natural voices already on your device, then fine-tune speech rate and pitch with simple sliders until the cadence feels right. Preview any voice before you set it. GENUINELY PRIVATE Everything stays on the device. No accounts, no sign-up, no cloud upload, no analytics, no ads. Buttons, photos, and settings are stored locally. Oggy never phones home — what your family says is nobody else's business. PARENTAL CONTROLS BUILT IN A PIN-protected lock keeps the settings out of small hands, so taps during real conversations never rearrange the board by accident. Unlock with Face ID or Touch ID where supported, with the PIN always available as a fallback. SIMPLE, FAIR PRICING Start free with up to 12 buttons and every core feature — all the voices, full customization, and parental controls. When you're ready for more, unlock unlimited buttons and all future features for $9.99/year. That's a fraction of what traditional AAC apps charge, and it keeps Oggy free of ads and data harvesting. BUILT BY SOMEONE WHO CARES Oggy is made and maintained by a solo developer focused on making communication tools that families can actually afford. Your subscription funds ongoing updates and new features. MORE ON THE WAY Multiple boards (one per child or context — "morning routine," "at school"), predictive next words, cloud backup to move between devices, and additional voices. Every future feature is included with your subscription. MADE FOR • Parents and caregivers of nonverbal or minimally verbal children • Speech-language pathologists and AAC specialists • Adults who use AAC for any reason • Anyone who needs a fast, simple way to say prepared phrases out loud FREE VS.
