iPhone
Don't just measure noise — keep records. Auto-timestamped sessions, weekly pattern heatmaps, and PDF reports to hand over. Light on ads. One-time purchase.
Footsteps upstairs, loud neighbors, nearby construction. This app turns "it's too loud" into timestamped, numeric records.
Every session is automatically timestamped and cannot be edited afterward. Your records build into a day-of-week × hour heatmap, so patterns like "every night around 11 PM" become obvious at a glance. Select a period and export a PDF report you can hand straight to your property manager or landlord.
