Companion control apps
Phone apps that set up a product, show status and give the owner a clear control surface after purchase.
Mobulous is a mobile app development company that builds the phone side of physical products: pairing, device state, field support and the schedule work that sits around certification. We do not sell sensor kits or claim protocol stacks as shipped products. 700+ apps delivered, 12+ years.
Hardware app development here means the companion application on the phone, not the circuit board. A mobile app development services team owns screens, pairing flows, state and support tools. Radio choices, chipsets and certification programmes are decisions your hardware side still has to make.
Connected-device proof and lab R&D sit below, shared with our IoT app development company page: Syrotech camera control as shipped work, then Rokid glasses and AI fitness sync as prototypes.
Phone apps that set up a product, show status and give the owner a clear control surface after purchase.
First-run flows that claim a unit, confirm identity and recover when pairing fails. Support tickets cluster here more than anywhere else.
Honest status when the phone and the device disagree, including offline and last-known values.
Registration, diagnostics and support surfaces for units already in homes and warehouses.
Consumer and operator apps for physical products that stay useful after the unboxing video ends.
When the product is worn on the body, health data and platform constraints are covered on our wearable app development company page. Hardware control still starts with pairing and state.
Software for a hardware product does not ship when the software is ready. Trace what it waits on. This is a schedule picture, not a provisioning or OTA engineering brief. Those topics live on the IoT app development page.
Simulators do not reproduce real radio behaviour, and a phone cannot pair with a device that does not exist yet.
Firmware usually runs on a different schedule and often at a different company. The app waits on that train whether or not your mobile backlog is empty.
If the accessory connects to an iPhone over Bluetooth classic or Lightning, Apple's programme is a commercial application with real lead time. It can gate launch before any code path matters. Treat it as a decision and a calendar item, not as a badge we claim to have already cleared for you.
Required to use the Bluetooth name and logo. Qualification is a programme choice with its own queue, separate from app store review.
Rules differ by market and decide where you can sell. Software readiness does not move those dates.
Measured in months in most hardware businesses. It does not compress because the app build is finished.
Each revision the factory ships is a revision the app has to keep supporting, including older units already in the field.
Early builds often have a handful of boards. Store-quality confidence waits on volume you can put in real hands.
Buyers, seasons and channel slots land on the calendar from outside the engineering room.
On a hardware project, the app team is rarely the critical path, and a schedule that assumes otherwise will be wrong. The useful question at scoping is not how long the app takes. It is what the app is blocked by and when those blockers unblock.
Pairing failures create more support tickets than almost any other surface in hardware companion apps. Radio technology is a product decision: Bluetooth Low Energy, classic Bluetooth, Wi-Fi, or another transport each changes range, power and permission prompts. We scope the app against the choice you lock. We do not sell a kit or claim a preferred stack as shipped expertise.
Clear steps, timeout handling and recovery when the phone never sees the device. Users abandon products that fail here.
Background limits on iOS and Android differ. The app has to say what it can and cannot do when the OS suspends radio work.
Bluetooth and local-network permission prompts change with platform releases. Upgrades break flows that used to work. Plan for that in support copy and release testing.
Getting a device onto a network from a phone is a common companion-app job. Credential entry, failure states and retries belong in scope before UI polish. Deep provisioning architecture is covered under IoT app development.
Phones and devices drift. One side updates while the other is offline. Battery on the device side limits how often state can refresh. The app has to show last-known values, conflict rules and what the user should do next without inventing certainty the radio cannot prove.
Firmware update mechanics and OTA rollback design belong with connected-device engineering on the IoT app development company page. Here the schedule question stays separate: update programmes and certification still sit on the critical path even when the mobile screens are finished.
Decide which side wins when timestamps disagree, and say so in the UI.
Device-side battery limits how chatty the link can be. Aggressive polling looks fine in demos and fails in the field.
OS rules restrict silent reconnect. Design for foreground truth and honest deferred sync.
Hardware revisions keep shipping after the first store release. Older units stay in homes. The app has to keep talking to both. When the product line ends, the app still needs a clear story for owners who refuse to throw the device away.
New boards, new sensor layouts and changed identifiers all land as app compatibility work. Plan version detection early.
Field inventory rarely upgrades in lockstep. A release that only works on the newest SKU creates support debt overnight.
When manufacturing stops, decide what the app still offers: read-only history, limited control, or a sunset notice with a date.
QR, MAC, model and serial registration reduce ticket noise. See the Syrotech camera-control card below for shipped connected-device proof, also covered on our IoT app development company page.
One strong connected-device client example beats a carousel of unrelated apps. Syrotech is genuine IoT work: camera provisioning, live control, and multi-device management through a mobile interface built for the client’s internal use. Lab prototypes (Rokid glasses and in-development fitness sync) sit in the next section and are not cited as shipped client proof.
Camera management app for Syrotech’s internal use. Operators add and configure multiple cameras through the app, then control feeds live, including switching cameras on and off from the mobile interface. The work centres on provisioning, live control, and multi-device management for a single operator account.
Active exploration beyond the Syrotech client card above. Status is stated on every card. None of this is an established IoT service line or shipped case study.
Mobulous is prototyping an app that pairs with Rokid smart glasses, captures images from the device, and runs custom face-recognition code against those frames. The work covers pairing over the device SDK and session lifecycle, pulling stills or frames from the glasses, then choosing where recognition runs: on-device for lower data exposure and tighter hardware limits, or server-side for heavier models with added latency and transfer risk. Each path has different privacy and latency trade-offs. This is internal R&D, not a client delivery, and not a smart-glasses service line.

An AI fitness platform in development that syncs workout and body metrics through Apple Health and Google Fit, then uses that stream to generate training plans. Barcode scanning supports food and product logging into the same product surface. A multi-role admin layer covers coaches, operators, and end users without collapsing those permissions into one account type. The health sync path is being built and tested in this prototype; it is not cited as a shipped client case study on this page.

Custom hardware app development for teams that already own a device roadmap. Primary work is mobile app development for hardware devices: companion UX, integration surfaces and field tools. Protocol names below are client decisions, not a catalogue of kits we sell.
iOS and Android apps that onboard, control and support a physical product through its life with the customer.
App-side work that talks to your hardware team's APIs, identifiers and status model. Stack choices stay yours.
Consumer and operator experiences for products that stay online after install day.
Clear commands, confirmations and failure states when a tap on the phone should change something in the real world.
When the product is a connected device fleet, provisioning and firmware paths are scoped with our IoT app development company practice. This page stays on companion behaviour and schedule.
Body-worn products share pairing concerns and add health-platform rules. See wearable app development for that vertical.
No week counts and no published prices on this page. Scope sets both after free discovery.
Functional discovery covers the product and users. Technical discovery covers platforms, device dependencies and delivery risks. Mutual NDA before detailed discussion.
Prototype availability, firmware owner, certification path and unit supply for testing are written down before UI commitments. App work waits on those gates whether or not anyone likes it.
Discovery becomes a scope document you keep. Proposal and agreement follow that artifact.
Simulators help early UI. They do not prove radio behaviour. Limits of each environment are stated in the plan.
Confidence rises with boards you can hold. Store submission waits on that evidence, not only on pixel review.
App Store and Play listing, policy and permission copy for hardware-related APIs.
Source code and IP transfer to the client on delivery. Four months free post-launch support is standard in every contract.

There is no single best vendor for every product. Prefer a partner that maps prototype supply, firmware ownership and certification before UI work, transfers source code and IP on delivery, and states post-launch support in the contract. Ratings such as 4.7/5 on Clutch (103 reviews) are context, not a substitute for those terms.
Mobulous builds companion and control apps for physical products: pairing, device state, field support and store submission. Radio stacks, MFi and factory schedules remain hardware-side programmes. Connected-device provisioning detail is covered on our IoT page.
Look for teams that separate app work from firmware ownership, write dependency gates into scope, and have shipped device registration or companion flows you can inspect. Ask what happens when phone and device state disagree before you compare design decks.
Scope determines cost. Free discovery produces a scope document before any proposal. This page does not publish price bands. Certification, unit supply and firmware readiness often dominate calendar cost more than screen count.
No. We build the mobile application side. Bluetooth, BLE, Wi-Fi, Zigbee, Matter, Thread, MQTT and chipset choices are decisions for your hardware programme. We do not sell sensor kits or claim those protocols as a delivered product line.
Commercial terms live in the agreement after scope. Discovery calls are free. This page does not publish milestone percentages, deposits or payment portals. Ask for the draft agreement once scope is written.
Early enough to map dependencies, late enough that a prototype or clear firmware owner exists. A schedule that assumes the app is the critical path is usually wrong once factories and certification offices are on the calendar.
Bring the device plan, the firmware owner and the certification path you already know. 700+ apps delivered, 500+ clients, 12+ years, 4.7/5 on Clutch (103 reviews). Mutual NDA before detailed discussion. Source code and IP transfer on delivery. Four months free post-launch support, standard in every contract.
