Bug Remover: Tone Generator

Bug Remover plays a high-frequency tone through your phone's speaker. Pick a target, press Start, and the app generates the sound live — no audio files, no ads, no account.

■ Presets by target

• Insects — sweeps 9–16 kHz, so it never settles on one tone

• Dog / Cat — sweeps 13–18 kHz, above most adult hearing

• Rats — sweeps 11–19 kHz, the widest band a phone speaker can deliver

• Humans — a steady 17 kHz that teens and people in their 20s hear, but most adults do not

■ Simple controls

• Frequency and volume slide so every step is audible)
