MobileCommand
A focused iPhone and iPad command surface for the road, the trail, and the evidence left behind. MobileCommandISR brings live vehicle telemetry, useful iPhone context, and trip history together—then presents the information that matters at a glance.
Build 37 preview
iPhone + iPad
CarPlay within Apple limits
Drive
Fuel, range, efficiency, temperatures, powertrain, and electrical status
Trail
Attitude, wheel speeds, altitude, horsepower history, and trail vitals
Trips
Drive and off-road history, fill-ups, route points, details, and export
Health
Read-only emissions readiness and diagnostic trouble-code awareness
Two data streams · one resolved picture
Vehicle first. The iPhone adds the context the car cannot.
MobileCommandISR does not replace vehicle data with phone estimates. It uses each source where it is strongest, preserves provenance, and falls back conservatively when a signal is unavailable or not yet trusted.
Source, augmentation, and fallback
- Core Location altitude, position, course, and route points
- Calibrated phone motion for pitch and roll fallback
- Cross-checking and context when vehicle attitude is provisional
- Clear source labels instead of pretending every value came from the ECU
One honest display layer
- Validated vehicle data takes priority
- Trusted phone profiles can supply a safe fallback
- Raw, derived, demo, and unavailable states remain distinct
- Calibration history and confidence stay attached to the result
Designed as a three-surface system
iPhone
Compact live drive, Overland, trips, telemetry, and setup.
iPad
The full, information-dense Trail and trip command surface.
CarPlay
A simplified glanceable screen within Apple's allowed templates.
Build 37 preview
Choose the attitude view that works for you.
Choose persistent Twin Vehicle Dials or an aircraft-style Attitude Ball across the iPhone and iPad Overland views. Both use the same resolved telemetry and calibration path, so the presentation can change without changing the underlying truth.
Screenshots demonstrate current software presentation and responsive layout. Demo or simulated values are not presented as proof of an exact-vehicle signal.
The app experience
What you need during the drive—and the evidence after it.
The current development build already connects, records, calculates, and presents a substantial vehicle picture. Broader vehicle support will follow only after each signal and adapter path is proven.
Live Drive
- Fuel remaining, fuel flow, and distance to empty
- A true rolling three-minute MPG view
- Speed, RPM, odometer, and key temperatures
- Gasoline/EV share, hybrid status, and 12-volt health
Overland + Trail
- Selectable Twin Vehicle Dials or Attitude Ball
- Individual speed from all four wheels for comparison—not traction diagnosis
- Gasoline-engine horsepower history and altitude
- Glanceable trail vitals with calibrated source handling
Trips + Fuel
- Separate Drive and Off-Road trip records
- Fill-ups, history, details, and deletion controls
- GPS route points and CSV export
- Manual trip control today, with zero-touch lifecycle planned
Quiet Health
- Standard emissions readiness and diagnostic monitoring
- Confirmed, pending, and permanent trouble-code records
- Useful awareness without programming modules or clearing codes
- Health evidence retained alongside the drive context
Fuel Ahead + Widgets
- Nearby fuel searches weighted toward the current direction of travel
- Driver preferences for more relevant results
- Glanceable widgets for useful vehicle information
- Route awareness and optional live prices remain future considerations
CarPlay
- Simplified Trip and Trail summaries using legitimate Driving Task templates
- Only permitted instrument counts, layouts, and refresh behavior
- A focused glance surface—not a free-form copy of the iPad screen
- Final presentation remains subject to Apple's platform limits and review
Adapter compatibility
Built around a reliable Bluetooth OBD-II connection.
The adapter transports requests and replies. MobileCommandISR supplies the Toyota-specific requests, decoding, validation, and calculations. A marketing claim of “enhanced data” is not the same thing as working with this app.
Tested + recommended
Vgate vLinker MC+
The only adapter physically validated end to end with MobileCommandISR and the exact sixth-generation 4Runner. It has handled the app's normal targeted standard and Toyota-enhanced polling reliably. For someone buying specifically for MobileCommandISR, this is the current reference choice.
iPhone discovery name
vLinker MC-IOS
Current transport
Bluetooth Low Energy
Purchase guidance
Genuine iOS/BLE model
Scheduled for validation next
These models are already represented in the next closed field-validation group. Until that work is complete, they are not recommendations or confirmed support.
Carista EVO
Scheduled across two vehicles. Direct MobileCommandISR connectivity and sustained data behavior remain unvalidated.
OBDLink CX
A strong BLE candidate for iPhone testing, but not yet physically validated with this app and vehicle family.
Veepeak OBDCheck BLE
Queued to broaden real-world BLE coverage beyond the current vLinker reference path.
Another vLinker MC+
A second MC+ reference will provide a controlled comparison on another vehicle.
OBDLink MX+
Its Bluetooth Classic path does not match the app's current CoreBluetooth BLE transport. A BLE alternative is required unless the architecture changes.
Future validation queue
Additional models on the compatibility watch list will follow after the next scheduled group. They are future checks—not support or purchase recommendations.
Veepeak OBDCheck BLE+ / BLE+ Plus
Research-backed iOS BLE candidate awaiting direct MobileCommandISR and Toyota-platform testing.
Vgate vLinker FD+
Queued for later transport and targeted-polling comparison with the validated MC+ path.
Vgate iCar Pro BLE 4.0
A lower-priority Vgate alternative awaiting direct app, vehicle, and sustained-drive validation.
BlueDriver Pro
Included in the original intake list, but no project evidence currently establishes an open data path usable by MobileCommandISR.
FIXD Sensor
Included in the original intake list, but no project evidence currently establishes custom third-party interoperability.
Compatibility status is specific to MobileCommandISR's current iOS Bluetooth Low Energy architecture. This is a validation priority list—not a universal quality ranking of OBD-II products.
Coming next
The app will grow by proving each layer first.
Planned features focus on making the existing experience more automatic, more personal, and easier to carry across Apple devices. Exploratory ideas remain clearly separate until the underlying signals and services can be trusted.
On the product roadmap
- Broader vehicle and adapter validation using the same evidence workflow
- Zero-touch trip start and stop
- Private sync across a driver's Apple devices
- Richer trip maps, elevation review, and pause/resume
- VIN-scoped calibration and stronger per-vehicle profiles
Being explored
- An app-owned route for true route-aware Fuel Ahead results
- Optional live fuel prices if a practical provider and cost model exist
- Pause/resume, richer trip maps, elevation, and longer-term efficiency views
- Apple Watch and Live Activity glance surfaces
- Traction interpretation and combined hybrid output only if the underlying signals can be proven
Vehicle scope
Starting with the sixth-generation 4Runner. Built to expand carefully.
Current product support remains limited to the sixth-generation Toyota 4Runner. Other GA-F vehicles below are future validation targets, not announced support.
Sixth-generation Toyota 4Runner
The exact vehicle path used to validate the vLinker MC+, live drive data, trip evidence, fuel signals, and the current development build.
GA-F platform expansion targets
2022+ Tundra
2023+ Sequoia
2024+ Tacoma
2024+ Land Cruiser
2025+ 4Runner
Validation is planned across Tundra, Sequoia, Tacoma, Land Cruiser, and additional sixth-generation 4Runner configurations before broader support is announced.
Coming soon
A clearer relationship with the vehicle you already drive.
MobileCommandISR is being built to make complicated vehicle data useful at a glance— during the drive, off pavement, and long after the trip ends.
Upcoming product preview as of July 30, 2026. Build 37 screenshots use simulated telemetry. Feature, adapter, vehicle, CarPlay, pricing, and public-release plans may change as physical testing and Apple review constraints are resolved. MobileCommandISR uses read-only OBD-II/UDS requests; it does not program vehicle modules or clear codes. Toyota, Apple, CarPlay, and adapter product names are trademarks of their respective owners. No adapter manufacturer sponsors this recommendation.
