Every Leg of the Trip, in One App
How Elevate built MotorMouth, a family travel app that tracks every leg of a journey in real time. Drives, flights, layovers, and connecting drives, all in one place, across phone, web, and voice.
MotorMouth set out to fix one of the most fragmented experiences in modern life: keeping a family connected through a multi-leg journey. Drive to the airport, fly across the country, land, get a ride home. Each step lives in a different app, with no shared view. MotorMouth ties every leg together as a single trip, visible to the whole family in real time, across phone, web, and voice.
An app that finally tracks the whole journey
Family travel had become a stitched-together mess of apps. Google Maps for the drive to the airport, the airline app for the flight, a text thread for “we landed,” another rideshare app for the drive home. Anyone tracking a family member’s progress had to bounce across four or five tools and still miss half the picture.
The MotorMouth founders had a clear thesis: a trip isn’t one mode, it’s a chain. The right product would model the journey as multi-leg, multi-modal, and surface the whole thing in one place. They came to Elevate to build a product that treats a drive-flight-flight-drive as a single trackable journey for the whole family.
What We Brought to This Project
MotorMouth needed a partner who could build the full product end-to-end. That meant a journey data model flexible enough to chain drives and flights together, live integrations with flight data and vehicle APIs, native iOS and Android apps where the experience feels primary, and an Alexa skill sophisticated enough to answer “where is everyone right now?” by voice.
Elevate’s US-based engineering team owned the build. We designed around the multi-modal thesis, integrated the data sources that make real-time tracking work, and shipped a product the founders are now positioning to travel and automotive acquirers.
Why nobody had stitched it together
An end-to-end view of a family journey has obvious demand. The reason it didn’t exist already was that every adjacent player had a structural reason not to build it. Google Maps stops at the airport curb. Airline apps only track the flight. Family locator apps don’t model journeys at all. Connecting them into one view requires data, integrations, and a UI no single incumbent had any reason to ship. MotorMouth needed all of it built from scratch.
No existing app modeled a trip as a chain of legs
Google Maps does drives. Airline apps do flights. Family locators do people. None of them stitched it together into a single trip the whole family could check. The trip data model itself had to be invented.
Vehicle APIs vary wildly across brands
Tesla has its own constantly-changing API, while most other manufacturers run through SmartCar at a per-vehicle cost. Every integration came with its own auth flow, rate limits, and reliability profile to manage.
A voice skill sophisticated enough to be useful
“Alexa, where is Mom?” is easy to say and hard to ship. The skill needed to handle people, vehicles, trips, multi-leg journeys, and more than 30 vehicle commands with natural phrasing and instant feedback.
True feature parity across four platforms
iOS and Android apps had to behave identically, the web interface had to add capability rather than just mirror the phone, and the voice skill had to feel native rather than like a wrapper around a mobile app.
Real-time data from very different sources
Flight status from FlightAware. Drive ETAs from mapping APIs. Vehicle location from Tesla and SmartCar. Security wait times from airport feeds. Every source has its own auth, rate limits, and update cadence to reconcile.
The Core Problem
The market needed a product the incumbents structurally couldn’t ship, which meant building everything from scratch.
Trip Coverage
Where each app stops, and where MotorMouth keeps going.
The journey engine, and everything around it
Elevate built MotorMouth around a unified data model that treats a multi-leg journey as a single object. Every interface (phone, web, voice) pulls from the same backend, so a trip created on the laptop shows up instantly on a kid’s phone or in an Alexa query from the kitchen.
Multi-Leg Trip Engine
The core of the product. A trip is a chain of legs (drive, flight, layover, flight, drive) tracked as one object with one status. Create it once and the whole family sees it.
Live Flight + Drive Status
Real-time flight data (gate, security wait, estimated departure, arrival) and live drive ETAs roll up into one trip view. No more bouncing between four apps to see where a family member actually is.
Voice Trip Queries
“Alexa, trip update.” One sentence returns the active leg, ETA, gate changes, and security wait. Most useful when you’re cooking dinner and someone’s flying home.
Family-Aware Tracking
Every trip is attached to a family member. The map view shows everyone on one screen with status (driving, in flight, walking, home), so no one has to ask “where is she now?”
Connected Vehicles in the Loop
Tesla direct and SmartCar for 36+ brands. The vehicle becomes the GPS source for the drive legs, with control surface (unlock, climate, secure) for the start and end of a trip.
Phone, Web, and Voice in Sync
Create a trip on the laptop, watch it from the phone, ask Alexa for updates. All three interfaces draw from the same trip model in real time.
Built for every screen from the ground up
Elevate’s architecture treated cross-platform as the requirement, not the afterthought. A shared backend handles auth, family graph, vehicle state, and trip logic. Every client, iOS, Android, web, and Alexa, hits the same APIs and gets the same data, so a trip created on the web shows up immediately in the Alexa skill.
Vehicle integrations are abstracted behind a single internal interface, so adding a new brand (or switching out SmartCar for a direct integration on high-volume vehicles) doesn’t touch product code. The Alexa skill itself is engineered around utterance patterns that handle natural phrasing, so users aren’t trapped in rigid command syntax.
A category-defining product, market-ready out of the gate
The MotorMouth product Elevate built is already what the founders set out to make: the only software that combines family location, vehicle control, trip monitoring, and voice in one place. Technology-wise, it’s positioned as an acquisition target for travel, automotive, and hardware companies.
iOS, Android, web, Alexa
via Tesla + SmartCar APIs
vehicles, trips, and home
First all-in-one product in the category
No competitor combines family location, vehicle control, trip monitoring, and voice across this many platforms. The structural gap that protected MotorMouth from incumbents now protects the moat.
True cross-platform parity from launch
Phone, web, and Alexa all draw from the same backend. A trip created on the laptop is instantly available by voice. No double-entry, no sync gaps.
Voice skill exceeded category norms
30+ commands across people, vehicles, trips, and home. Natural phrasing handled gracefully. Most car-brand Alexa skills don’t approach this level of sophistication.
Ready for hardware partner expansion
The clean internal API layer means new partners (Tile, AirTag, Jiobit, dog collar trackers, elder trackers) can plug in without product-code changes. Phase-two growth is unblocked.
“What was supposed to be impossible for a single team is shipping today as one cross-platform product that no incumbent can match.”
A market-ready product, positioned for what’s next
MotorMouth is technology-ready: shipping product, validated architecture, multi-platform footprint, and a voice skill that does what its closest competitors can’t. The cross-platform thesis the founders started with is now a working product that travel companies, car companies, and hardware manufacturers all have reason to look at.
Elevate continues to support MotorMouth as the team explores hardware partnerships, additional vehicle brand integrations, and scaling for the install bases of Alexa, Tesla, and the family-tracking market. The work is delivered by US-based senior engineers using AI-assisted tooling, with a team that treats the MotorMouth roadmap as their own.
