INTERACTIVE LABS Most study apps show you a diagram. These let you move it. Sweep an input through ReLU, sigmoid and tanh and watch the dying-ReLU flat zone appear. Step a ball down a loss curve, then push the learning rate past 1.0 and watch it diverge. Drag a query point across a k-NN decision boundary and see the vote flip. Tap "it" in a sentence and watch self-attention land on "laptop". Shrink an autoencoder bottleneck until the reconstruction blurs. Turn retrieval off in a RAG pipeline and watch a confident, wrong answer appear. Eighteen labs in total. All of them run on your device with no connection. BUILT FOR HOW PEOPLE ACTUALLY STUDY - Five-minute sessions. Choose 5, 10 or 15 questions instead of grinding through a 152-question bank you'll never finish in one sitting. - Every option explained. Most apps tell you the right answer. This one explains all of them, so a wrong guess still teaches you something. - A review queue that adapts. Missed questions come back automatically and leave once you've got them right. - Progress you can see. Daily streak, best score per certification, questions answered, and how many are still waiting for review. - Works on a plane. Every question ships inside the app. MORE THAN A QUESTION BANK The Briefing tab keeps you current between study sessions: AI Daily News, the DjamgaMind podcast playable on your lock screen, and live job listings. The Practice tab carries 16 tutorials, 10 of them full step-by-step walkthroughs you read inside the app, covering Amazon Bedrock, Azure AI Foundry, Vertex AI, prompt engineering and RAG, and the coding agents professionals use daily. NATIVE, PRIVATE AND QUIET Siri Shortcuts let you say "Practice offline" to start a session. Daily study reminders are scheduled locally by iOS. Dark mode is supported throughout. Your quiz history, streak and review queue are stored on your device and never uploaded. There is no account to create, no analytics SDK and no advertising SDK in the app. Want the full question banks and all 18 labs? AI & ML Tutor PRO is our separate paid app. Questions, or a certification you'd like added? https://machinelearningcertification.web.app
