Mobile Location & Maps Integration

Location looks like a small feature until the first invoice arrives or the first user writes in about a flat battery. A delivery app showing a driver nearby, a rental service offering the closest branch, a field team alerted when a technician reaches a site: each needs the same decisions early, and each costs accuracy, battery life or API spend.

Drawing a pin is the easy part. The rest is deciding how accurate the position must be, how often the app asks, what happens when the user says no, and what the map provider charges. We build that layer for iOS and Android, with the monthly bill predictable.

What location work covers

Three jobs sit behind most location requests. Display means a map, the user's position, markers and a route between two points. Watching means a geofence around a site or a zone, with an alert when a device enters or leaves. Reporting means sending positions to a backend, so dispatch and arrival estimates have something to work from. An app may need one or all three, and each costs differently in battery and provider requests.

Who this is for

• Fleet and field service operators who need vehicle or technician positions on a map, with trip history and replay
• On-demand services such as cleaning, repair and delivery, where dispatch depends on where people are
• Rental and booking businesses where the customer picks a branch or the nearest location
• Property, travel and event products that show places and walking routes, or trigger an offer on entry to a zone

What we deliver

Maps, routes and place data

We work with Google Maps Platform, Apple MapKit, or both when an app ships on two platforms. That covers map rendering, custom markers and clustering, address search, reverse geocoding, distance matrices and route display. Anything the provider does not draw, we build ourselves.

Geofences and location-aware alerts

We register fences around the places that matter, confirm the platform boundary events on the server so one noisy reading does not produce three notifications, and route the alert in the app or to the operator on a dispatch screen. Alerts pair with the push notification layer when a message must arrive while the app is closed.

Accuracy, battery and update frequency

Accuracy is a dial with a cost on the other side. Infrequent updates at low accuracy keep a phone alive for days and suit city coverage. Polling at high accuracy every few seconds serves a live tracking screen and empties a battery in hours. We set the dial per feature: precise updates while a trip or shift is active, significant-change updates while the phone sits idle, none when the user is off shift.

Permissions, denial and degraded modes

Both platforms let a user grant approximate location, deny it, or allow it only while the app is open. We ask when the request makes sense, with a short line explaining what the feature does, instead of on first launch. When permission is denied or limited, the app falls back to a typed address, a branch picker or a saved home location, so core flows keep working.

Background location on iOS and Android

Background tracking gets apps rejected and users annoyed. iOS expects a clear use case and the right background mode, shows the user a periodic reminder while an app keeps using location, and limits how long background execution runs. Android splits location into foreground and background permission, asks for them separately, and applies battery restrictions that vary by manufacturer, so the same job can behave differently on a heavily skinned phone. We run background tracking where the product needs it, such as an active delivery, and stop it when the shift ends.

Collecting less location data

Continuous location is the most sensitive data an ordinary app holds: it shows where someone sleeps, works and visits a clinic. Our default is the least the feature can work with: precise coordinates only while a trip is active, coarse position or a city name for discovery, and no history stored on the phone or the server unless a product feature needs it. Where history is required, such as a fleet's trip replay, we agree a retention period, keep access behind roles, and document what leaves the device. We prepare the iOS privacy manifest and the Play data safety form, since both stores ask about location specifically.

Where the project starts

Three starting points change the plan.

A plain idea, where nothing exists yet. We choose the platform, scope the smallest location feature set that proves the concept, and usually ship with foreground location only. Background tracking moves to a later phase.

An existing conventional codebase, built by a team still around or long gone. We audit how the app asks for permission, where its map keys live, how often it polls and what it stores, then work inside the current architecture: upgrading an old maps SDK, throttling an update loop, or adding a map screen.

An AI/vibe-coded prototype, where features appeared faster than the location plumbing. These apps often carry a map key in the client bundle, request background permission on first launch, and fire duplicate geofence events. We keep the interface and the parts that work, then rebuild the location layer to a standard that passes store review and protects the data it collects.

How an engagement runs

Discovery covers what the features must do and who depends on them. Then we map the request volume one active user creates, so the provider cost is known before the build. The build runs in phases: map and position, then alerts and geofencing, then background tracking and dashboards if needed. Testing happens on real devices and real routes, with the screen locked and battery in low power mode.

What it costs

Location work is quoted at our flat rate of $39 per hour, or as a fixed scope once the requirements are clear. A mobile MVP with map display, a few markers and route drawing typically lands inside the mobile MVP range published on our pricing page: $4,800 to $8,500 across four to six weeks, where the rest of the app is built alongside it. Geofencing, alert delivery and a server-side event pipeline extend the build by a phase. Continuous background tracking with a fleet dashboard and trip history is closer to a product of its own.

Two variables drive the size: how often the app needs a position, and how much work happens while the phone is in a pocket. Provider fees for maps, geocoding and routing are separate and scale with usage.

Proof

Naviaddress turns long postal addresses into short digital codes, and we built its iOS and Android apps. Locations could carry route descriptions and photos, which shows we can treat a place and its metadata as the primary data model.

CBAY Rent A Car takes bookings with pick-up and return locations tied to vehicle availability, pricing and staff workflow. It covers the location input side: branch selection that has to be right because a vehicle and a payment depend on it.

TrackVision Tech is a GPS tracking and fleet management platform with live map views, alerts, trip history and route replay. It shows what we do with continuous location streams once several vehicles report at once, and how a dashboard stays readable for a fleet operator.
