Horizontal Accelerometer is a free utility for measuring real-time horizontal acceleration and lateral G-force on iOS and iPadOS devices.
The App DNA
What makes this app unique?
It removes the need for expensive, dedicated hardware when measuring acceleration for educational physics experiments or driving performance monitoring.
For Automobile drivers interested in monitoring driving dynamics and engineering students studying equations of motion.
What does it look like?
Key features
Visual and auditory alerts trigger when acceleration values exceed user-defined thresholds for Red and Yellow zones.
Toggles a software filter to ignore impact vibrations and noise during measurement.
Saves and recalls specific device orientation and calibration settings for consistent measurement across different mounting surfaces.
How much does it cost?
The app is distributed as a free utility with no visible in-app purchases or subscription tiers.
Velocity
Dormant developmentperformanceShow more...
Horizontal Accelerometer has been inactive for 262 days, falling well outside the threshold for active development. The only release in the observed window was a minor update focused on performance and bug fixes. There is no evidence of new features or ongoing support, characterizing the app as a zombie project.

Competitive landscape for Horizontal Accelerometer
How's the Utilities market?
Horizontal Accelerometer occupies a niche, non-commercial position in the Utilities category. The lack of updates for 262 days signals a maintenance-only posture that prevents it from competing with active, sensor-integrated automotive diagnostics.

The Analyst's Read
Key takeaways for Horizontal Accelerometer
Where is it heading?
The automotive utility market is consolidating around apps that provide automated, sensor-integrated data logging. Horizontal Accelerometer's manual, static design leaves it exposed to obsolescence as users migrate to tools that require less calibration and offer deeper vehicle-data integration.
- The 262-day update gap indicates the app is in maintenance mode, which prevents it from adopting modern sensor-fusion capabilities found in rival diagnostic tools.
The SWOT
- Customizable color-zone thresholds enable personalized driving-performance tracking
- Integration with vehicle-specific mounting hardware could establish a specialized distribution channel

Read the full takeBottom line
Horizontal Accelerometer serves a narrow educational niche, but the lack of active development and monetization makes it a sunset candidate. Reallocating resources away from this static utility would allow focus on higher-yield projects.
