Two field guides for learning to recognise flowers on sight, a photo-first flashcard deck for each, and a dashboard that turns your own guesses into a real classifier report card — precision, recall, F1, AUROC, calibration, the lot.
The 25 flowers you'll meet at an English florist — how to spot each one, what it means, and when it's British-grown vs shipped in, with an interactive seasonal wheel.
37 more — the ones you actually walk past. Front gardens, hanging baskets, walls and verges, plus a safety layer for dangerous look-alikes like hemlock and giant hogweed.
The full Flashdeck app — every deck, including both flower decks above and the classifier-metrics training deck (F1, AUROC, precision/recall). Photo quizzes, hard-lookalike sessions, spaced repetition.
Your guesses, scored like a real classifier — per-deck confusion matrices, precision/recall/F1, a learning curve, AUROC, and a calibration plot for your stated probabilities. No quiz session needed, just look.
Everything here is static and runs entirely in your browser — no account, no server. Study progress and guess history live in this browser's local storage, so the dashboard reflects this device.
