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.

Verdict

The call

Bug Identifier's advantage is ads (none vs shown) and update cadence (every 2 months vs every 19 months). On price, device support and iOS requirement there is nothing between them.
