Tiltometer vs SoundLevel

Tiltometer turns your iPhone or iPad into a precision inclinometer for off-road driving, overlanding, and trail riding. See your vehicle's pitch and roll in real time on animated gauges that move with your device. REAL-TIME TILT GAUGES Front and side vehicle silhouettes rotate live with your device orientation, giving you an intuitive read on pitch and roll displayed in degrees or percent grade. CUSTOMIZE YOUR RIDE Choose from 13 built-in vehicle silhouettes or upload your own photos to create a custom front and side profile that matches your exact rig. Apply a tint color and adjust opacity for the perfect look. TILT WARNINGS Set yellow and red alarm thresholds for each axis. Visual gauge overlays change color as you approach dangerous angles, and an optional audio alarm sounds when thresholds are exceeded. COMPASS & ELEVATION GPS elevation in feet or meters and compass heading with cardinal directions — magnetic or true north — are always visible at a glance. BUILT FOR THE TRAIL - Calibrate to zero on any surface - Adjustable gauge smoothing for steady readings on rough terrain - Screen stays on while the app is active - Works in portrait and landscape - No account or internet connection required

SoundLevel uses microphone amplitude to provide an approximate uncalibrated sound-level estimate in dB. Log sessions and compare how your estimates change across places and time. SoundLevel is not A-weighted, calibrated, or a certified measurement instrument. Values can vary by device, case, placement, and environment. Do not use the app for safety, occupational compliance, medical, or legal decisions. WHAT SHIPS - A large live estimate with approximate minimum, energy average, and maximum values - Descriptive level bands and familiar examples for personal comparison, not safety classification - A user-chosen threshold alert that is not a safety warning - Recorded sessions with history, search, sorting, notes, and charts - A rough guideline reference based on an 85 dB and 3 dB relationship when the estimated average is at least 85 dB - No guideline time or percentage calculated below 85 dB - Six-week summaries, week-over-week comparison, and highest logged estimates - A reference offset that shifts the displayed estimate but does not calibrate the device - A one-page PDF, CSV history, and share card with the limitations included - Local storage with no account, cloud sync, analytics, or tracking FREE VS LIFETIME The live estimate with minimum, average, maximum, level band, and reference offset is free. One lifetime purchase adds session recording, history and trends, threshold alerts, rough guideline comparisons, and PDF and CSV export. There is no subscription. SoundLevel provides approximate uncalibrated estimates only. It is not A-weighted or certified. Do not use it for safety, compliance, medical, or legal decisions.
