Engineering Modes - Case Studies and Practical Uses

Public beta

App Store availability will be defined soon.

Engineering modes turn your phone into a practical motion and vibration analysis tool.

These tools are meant for users who need more than a speed display or a map.

Who this is for

They are most useful when the question is practical, human, and tied to a real decision.

For city, road, and maintenance users

Use engineering modes when you need more than a subjective impression of road quality.

Does this road section need repair, or does it only feel bad subjectively?
Which lane, street, or district gives the roughest ride and the lowest comfort?
Did resurfacing actually improve road quality enough to justify the work?

For creators, dashcam users, and mount testers

Use engineering modes when usable footage matters more than how solid a mount feels by hand.

Is this camera or phone mount good enough for usable footage, or is it still amplifying shake?
Did adding damping improve the setup, or just make it feel softer while performing worse?

For workshop, maker, and machine users

Use engineering modes when vibration affects quality, durability, or confidence in a setup.

Should I improve my 3D printer table, feet, or support to reduce resonance, improve machine stability, and put less stress on the printer over time?
Is this bench, shelf, or support stable enough to keep using?

For custom vehicle builders and tuners

Use engineering modes when you need to understand whether a build change introduced or reduced a vibration problem.

Is my custom car build transmitting a resonance or vibration problem that I can measure and fix?
Did a hardware or mounting change reduce vibration enough to keep, document, or report?

This section collects practical case studies and decision-focused workflows that show what these modes are for and why they matter.

Pick the right tool

Use the mode that matches the question you are trying to answer.

Your question	Best tool	Why
Which complete setup or run feels better overall?	Motion Quality	Scores full sessions so you can compare whole runs, mounts, or surfaces
Is this recording setup smoother and more stable?	Camera Rig	Focuses Motion Quality on recording stability and mount behavior
Which route, lane, or surface is rougher?	Road Survey	Focuses Motion Quality on harshness, bumps, and road quality
What vibration frequency is causing the problem?	Resonance Scan	Finds dominant vibration behavior and resonance peaks
Did a hardware or damping change reduce the vibration source itself?	Resonance Scan	Lets you compare repeated setups and operating conditions directly

What engineering modes are good for

These modes are especially useful when visual judgment is not enough or when you need a cleaner before-and-after comparison.

testing phone mounts, dashcam mounts, and camera rigs
comparing before-and-after damping changes
checking whether a bracket, arm, or support is flexing
comparing route sections, lanes, and surface quality
documenting workshop or field tests with saved sessions and reports
turning trial and error into a repeatable test workflow

Motion Quality vs Resonance Scan

The two tools are related, but they solve different problems.

Motion Quality

Use Motion Quality when the result you care about is the overall quality of a complete run.

It is the better first tool when you want to compare:

one mount against another
one route section against another
one setup before and after a change
one lane or surface against another

Start here if your practical question is:

Which option performs better in real use?

Resonance Scan

Use Resonance Scan when the result you care about is the vibration behavior itself.

It is the better tool when you want to know:

where the strongest repeating vibration sits
whether the vibration got weaker after a change
which axis is carrying the strongest response
whether the system is resonating at a problematic frequency

Start here if your practical question is:

What is actually causing the vibration problem?

road comfort comparison, resurfacing validation, and route-quality documentation
dashcam, phone-mount, and camera-rig testing
cabin, dashboard, bracket, and mounting-point vibration diagnosis
printer, bench, shelf, and support vibration testing
before-and-after validation of damping, bracing, isolation, or relocation changes

Case studies

These pages show how engineering modes solve practical problems rather than only describing the interface.

Good first workflows

If you are new to engineering modes, start with one of these:

I want to improve a camera or phone mount

Use Camera Rig to compare the complete setup before and after a mount change.
If the rig is still unstable, use Resonance Scan to find the dominant vibration behavior.
Apply one targeted mechanical change.
Re-test and compare again.

I want to compare roads, lanes, or route sections

Use Road Survey on repeated runs.
Keep speed and route conditions as similar as practical.
Compare the saved sessions and report the difference.

I want to diagnose a vibration source directly

Use Resonance Scan .
Capture a clean baseline.
Change one variable only.
Compare resonance strength, dominant frequency, and axis response.

Why this section matters

Most users understand a speedometer app immediately. Engineering modes need one extra step: users must see the problem they can solve with them.

That is the purpose of this section.

It connects the mode to the decision:

what to test
why to test it
what result to look for
what change to make next
