MosquitoShield:Repellent,Guard

Mosquito Shield turns your phone into a mosquito defence kit: an ultrasonic repellent, a sound-based detector, a personal bite diary, and prevention guidance you can act on tonight.

🔊 ULTRASONIC REPELLENT

Emit a continuous 8–22 kHz tone with a single tap. Pick the Low, Mid or High preset, or tune any frequency you like with the slider. The tone keeps running with the screen off, shows an ongoing notification with a Stop button, and pauses automatically for phone calls. Set an auto-off timer so it never runs down your battery overnight.

🎧 MOSQUITO DETECTOR

Point your microphone at the buzz. The detector listens for the 300–800 Hz wingbeat signature mosquitoes produce and reports live confidence plus the dominant frequency it hears — along with a genus hint (Anopheles, Culex, Aedes) and the diseases each can carry. It all runs on your device.

📊 DETECTION HISTORY

Every listening session is saved. See how many windows were analysed, how many came back positive, what happened in the last 24 hours, and which genus turned up most often.

🩹 BITE DIARY

Log bites as they happen and watch your daily and weekly totals build up. Export the whole diary to CSV and share it with anyone — handy if you are tracking a reaction or talking to a doctor.

✅ DAILY PROTECTION CHECKLIST

A short list of the things that genuinely work, scored each day and reset every morning.

⏲️ REAPPLY REMINDER

Repellent wears off. Start a timer when you put it on and get a nudge when it is time to reapply.

🔔 DAWN & DUSK REMINDERS

Aedes and Anopheles bite hardest around sunrise and sunset. Optional nudges at 6 AM and 6 PM.

📚 PREVENTION & DISEASE GUIDES

Offline guidance on removing standing water, bed nets, EPA-approved repellents and window screens — plus what to know about dengue, malaria, Zika, chikungunya, West Nile and Japanese encephalitis.

📣 SIGHTING LOG

Record adult mosquitoes, breeding sites and bites with an optional area note and a photo. Saved on your device today; sharing with other people and the hotspot map are coming in a future update.

🔒 PRIVACY FIRST

Mosquito Shield asks for no location permission at all. Your detections, bites and reports never leave your phone.

⭐ PRO

Pro unlocks the 22 kHz Max preset, the 1-hour auto-off timer, your full 24-hour detection history, and bite diary CSV export. Unlock every Pro feature free by watching a short ad, or buy a plan to remove ads for good.

⚠️ AN HONEST NOTE ON ULTRASONIC REPELLING

Peer-reviewed studies have not found ultrasonic apps to reliably repel mosquitoes, and most phone speakers roll off above roughly 18 kHz. We say so inside the app too. Use the repellent alongside measures that are proven to work — nets, EPA-approved repellents and removing standing water — all covered in the Learn tab.

Mosquito Shield is not a medical device. It does not diagnose, treat or prevent disease.
