Monarch SOS is a field guide for the public as well as a citizen science reporting app. It is the first monarch app developed by scientists that covers monarch identification in all life cycle stages, confusing look-alikes and numerous milkweed species (monarchs' larval host plants), frequently encountered in North America. Monarch SOS is a valuable tool for learning about monarch butterflies, threats they face and how everyone can help bring back the monarchs by making a few simple lifestyle changes. If viceroy and queen butterflies confuse you, quickly learn the differences in the "Compare" section under each butterfly. Keep up with the latest information on monarch conservation efforts and migration news by checking in daily with What's New? The feed is updated every time you open the app, so you'll always be in the loop!

Know what bit you — and whether it's dangerous. BugAlert turns your camera into a fast bug, spider and bite identifier built for one moment: when you find something and need to know if it's a threat. Snap a photo and get three ranked matches with honest confidence, a clear danger flag, and what to do next. Built around the danger question • Colour-coded danger verdict on every result: venomous, bites, stings, disease-carrier or harmless. • "What bit me?" mode narrows welts and stings to a likely culprit — mosquito, tick, flea, bedbug, spider, ant or wasp — with first-aid steps and clear red-flag guidance on when to seek care. • Pest mode helps you tell a cockroach from a carpenter ant from a termite, read the signs of an infestation, and decide DIY vs. call a pro. Accurate, honest identification • Three candidates with confidence — never a single overconfident guess. • Species info: common and scientific name, reference photos, range and season. • Voice input for the bug that got away: describe it and get likely matches. • Every scan saved to your history. Important BugAlert provides informational identification and general safety guidance only. It is not medical, veterinary or pest-control advice. For a bite or sting that worries you, or a suspected infestation, consult a qualified professional. ——— This app requires a subscription to use.
