Apps that ship, connect, and stay alive in the field.
Tridence designs and engineers mobile and wireless products that real users keep on their home screens. Native iOS and Android, cross-platform, progressive web apps, and connected device experiences — instrumented, observable, and built to last beyond launch day.
An app is not a deliverable. It is a relationship.
Most agencies hand off a binary, take a check, and move on. The first 90 days post-launch are when the real work begins — store reviews, crash dashboards, OS updates, A/B tests, retention loops. We engineer for that day, not for the demo.
Ship it. Forget it.
Static spec. Waterfall handoff. No analytics. No retention strategy. No plan for OS updates. The app launches, ratings drift, and by month six it is a liability instead of an asset.
- One-time scope, fixed bid
- No telemetry baseline
- No store optimization
- No update cadence
- No on-call when production breaks
Ship it. Watch it. Improve it.
Telemetry from day one. Defined retention KPIs. Quarterly OS-update support. A/B tests on onboarding and core flows. App store presence treated like SEO. Production observability with humans on call.
- Sprint cadence — not a single delivery
- Crashlytics, Sentry, Amplitude wired in
- App Store Optimization (ASO) on launch
- OS-major-version readiness program
- 15-min on-call response, 24-hour patch SLA
From flagship native to edge-of-network wireless.
One discipline, many surfaces. Whether it lives in a pocket, on a wrist, behind a dashboard, or inside an industrial enclosure, we treat it as a connected product with users on the other end.
Flagship apps that feel native because they are.
Swift / SwiftUI on iOS, Kotlin / Jetpack Compose on Android. Performance, polish, and platform conventions when the brand bar is highest.
- iOS 16+ · Android 12+
- Apple Pay, Wallet, Live Activities, WidgetKit
- Material 3, predictive back, foldable layouts
- App Clips and Instant Apps for friction-free entry
One codebase. Two stores. No compromises that matter.
React Native or Flutter when speed-to-two-platforms beats per-platform polish. We pick the right tool, not the trendy one, and we know when to drop down to native modules.
- React Native + Expo, Flutter 3
- Native bridges for camera, BLE, secure enclave
- Hermes / impeller engine tuning
- OTA updates with EAS or Shorebird
Web-fast, install-prompt-ready, app-store-optional.
For products where a no-download path matters — retail, B2B portals, internal tools. Offline-capable, push-enabled, A2HS-friendly.
- Next.js, Service Workers, Workbox
- Web Push, Background Sync
- Trusted Web Activity for Play Store presence
- Lighthouse PWA score 100
Companion apps for the hardware in the room.
BLE, Wi-Fi provisioning, OTA firmware updates, MQTT, edge logic. We have shipped companion apps for fitness gear, industrial sensors, transit hardware, and home appliances.
- BLE pairing UX patterns that actually pair
- Wi-Fi setup with SoftAP / WPS / Matter
- OTA firmware delivery with rollback
- MQTT, CoAP, AWS IoT, Azure IoT Hub
Apps that survive a warehouse, a truck cab, a job site.
Offline-first sync. Barcode and RFID scanning. Signature capture. MDM-friendly distribution. Built for crews who are not at a desk and cannot tolerate the spinner.
- Offline-first with conflict resolution
- RFID, NFC, barcode, OCR
- MDM (Intune, Jamf, Workspace ONE)
- Ruggedized device targeting (Zebra, Honeywell)
Glanceable experiences for the wrist and beyond.
watchOS, Wear OS, CarPlay, Android Auto, tvOS. The interaction model is different at three inches and from the driver seat — we design for it from scratch, not as an afterthought.
- watchOS complications and Smart Stacks
- Wear OS tiles and ongoing activities
- CarPlay and Android Auto templates
- tvOS and Apple Vision Pro spatial layouts
Three tiers. One standard.
Whether you need a feasibility opinion, a flagship build, or a long-term mobile partner who keeps your apps healthy in the stores, the engineering bar does not change.

Discovery to day-90. The whole arc.
Mobile work that ignores the post-launch reality is mobile work that fails. Our process bakes telemetry, store strategy, and OS-update planning into week one.
Discover
User research. Competitor teardowns. Platform feasibility. Wireless protocol selection. We name the constraints before we name the features.
Design & prototype
Native-pattern UX. Clickable prototypes on real devices. Accessibility from the start (Dynamic Type, VoiceOver, TalkBack). Design system tokens shared with engineering.
Build & instrument
Two-week sprints. CI/CD with Fastlane and EAS. Telemetry wired in week one, not week ten. Real-device matrix QA. Beta via TestFlight and Play Internal.
Launch & sustain
Phased store rollout. ASO copy and screenshots tuned. Day-one observability dashboards. Quarterly OS-readiness reviews and a clear plan for the next 90 days.
Modern, boring, and battle-tested.
We pick tools that stay in business and stay maintained. No bleeding-edge framework du jour for client work — unless the client work is specifically about exploring the bleeding edge.
Mobile decisions, answered honestly.
Native or cross-platform — which should we pick?
It depends on three things: how custom the interactions need to feel, how performance-sensitive the experience is, and how big the team is. For most B2B and content apps, React Native or Flutter saves a lot of money for the same outcome. For flagship consumer apps with tight platform integrations — Live Activities, complications, deep camera or AR work — native is still the right answer. We will tell you which camp your project is in inside the feasibility sprint, with no preference for the more expensive option.
Do you build the backend too, or just the app?
Both. Most of our mobile builds include the API, auth, push, payments, and analytics infrastructure that makes the app actually work. We use Node, Go, Firebase, or Supabase depending on team shape and scale needs. If you already have an API, we integrate; we do not insist on greenfield.
What about IoT and BLE work specifically?
This is one of our specialties. We have shipped companion apps for fitness equipment, industrial sensors, transit hardware, and home appliances. We design the pairing UX, handle the protocol implementation (BLE, Wi-Fi provisioning, MQTT, Matter), and build OTA firmware update flows with rollback. We also know the failure modes — weak signal, dropped pairings, firmware version mismatches — and design for them.
Can you take over an existing app?
Yes. About a third of our mobile work is rescue or modernization — inheriting a codebase, stabilizing it, and getting it back to a healthy ship cadence. We start with a code and product audit, then a stabilization sprint, then a roadmap. We will not pretend the old code is fine if it is not, and we will not advocate a full rewrite if a refactor will do.
How do you handle App Store and Play Store submissions?
We own the submission process end to end. That includes ASO copy, screenshots, preview videos, privacy disclosures (App Privacy on iOS, Data Safety on Android), age ratings, export compliance, TestFlight beta cycles, and review-team responses. If your app gets rejected, we handle the appeal. We have shipped through every recent App Store policy change.
Pricing?
Tailored to scope · fixed-fee phases on builds · monthly retainer on continuous care · no flat-rate menus. We size the work after a 15-minute discovery and a feasibility sprint, not before. If a vendor quotes you a number on a phone call without seeing the work, that is the number for the wrong project.
Got an app idea, a stuck build, or a device that needs a companion?
We would rather see your wireframe and your store listing than your RFP. Fifteen minutes, real engineering opinions, no slide deck.
