Tell us your device, your iOS version, and what you were doing when it happened. If a lesson felt wrong or a number looked suspicious, quote it — we chase those.
Open the app, go to the paywall and tap Restore Purchases. If it still does not unlock, check that you are signed into the same Apple Account that made the purchase, then email us.
On your device: Settings → your name → Subscriptions → Neural Playground → Cancel Subscription. Cancelling at least 24 hours before the renewal date stops the next charge; you keep access until the period ends.
Not yet. Progress is stored on the device, which is also why we collect nothing about you. If this matters to you, tell us — demand decides what gets built next.
It is written for anyone curious about how AI actually works, and the explanations start from zero. Younger readers do fine with an adult nearby for the harder chapters. There is no chat, no user content, and no way for anyone to contact a user through the app.
On purpose. Every network in the app really runs on your phone, so every number you see is real rather than an animation. Small enough to be honest beats big enough to impress — and where a toy cannot do what a large model does, the lesson says so out loud.
Please tell us. Accuracy complaints go to the top of the queue, and we will name the fix in the release notes.
