Tactical Mobile App Development

The Challenge

Building mobile software for the enterprise is solved. Building it for the field is not. Operators in rugged environments face a fundamentally different set of constraints than office workers — and most commercial mobile frameworks were never designed to accommodate them.

Intermittent Connectivity

Denied, degraded, intermittent, and limited (DDIL) environments make cloud-dependent apps useless the moment the LTE handoff drops. Every data model must assume the network will not be there.

Battery & Power Constraints

Extended field operations demand aggressive power budgeting. Background sync cycles, GPS polling intervals, and radio wakeups must be tuned to mission duration, not benchmark scores.

Gloved Operation & Rugged UX

Operators wearing gloves, in poor lighting, under stress cannot navigate a consumer UI. Touch targets, contrast ratios, one-handed operation, and error forgiveness are non-negotiable design requirements.

ATAK Ecosystem Compatibility

The Android Tactical Assault Kit (ATAK) and TAK ecosystem is the de facto field situational awareness standard for many allied forces. Custom plugins and data feeds must conform to the ATAK SDK and Cursor-on-Target (COT) data model.

Secure Data Handling

Sensitive operational data captured in the field — grid coordinates, personnel positions, SIGINT observations — must be encrypted at rest and in transit, with remote wipe capability and tamper-evident audit logs.

Disconnected Operations

Forward-deployed units need full application capability — map display, data entry, task management, and comms — with zero dependency on a reachable server. Sync happens when connectivity permits, not when the operator needs to act.

What We Build

We design, build, and field-test mobile applications from the ground up for defense, public safety, and critical infrastructure operators. Every deliverable is purpose-built for the EDC (everyday carry) kit of personnel working at the edge.

Ruggedized Android & iOS Tactical Apps

Cross-platform and native apps hardened for Zebra, Samsung Galaxy XCover, and other MIL-SPEC-grade devices. Large touch targets, high-contrast themes, and simplified navigation for stressed, gloved operators.

Offline-First Data Capture with Sync

SQLite and Realm local stores as the system of record. Conflict-resolution sync engines deliver data to back-end systems when connectivity is restored — no data loss, no duplicate records, no manual reconciliation.

ATAK Plugins & Integrations

Custom ATAK SDK plugins that surface mission data, sensor feeds, and C2 messages inside the TAK operator interface. COT message handling, TAK Server integration, and bridge connectors to allied COP platforms including Ukraine's Delta system.

Encrypted Mesh & LoRa Comms

Peer-to-peer encrypted messaging over Bluetooth LE mesh networks and LoRa radio links for teams operating beyond cellular coverage. Sub-kilobyte message framing keeps transmission costs low over long-range, low-bandwidth channels.

Field Survey & Reporting Tools

Structured data collection for damage assessment, route reconnaissance, site surveys, and incident reporting. Form schemas defined centrally and pushed to devices; completed records queue for upload with photo, GPS, and timestamp metadata.

Map-Centric Operator UIs

Mapbox GL Native and MBTiles offline tile bundles give operators a full moving-map experience with zero network dependency. Custom layer rendering for unit positions, threat overlays, grid references, and annotated imagery from UAV feeds.

Proven Field Delivery

Corvus Intelligence has delivered field-level software to clients deploying Corvus.Head — our unified battlefield intelligence dashboard — at the company and battalion level within Ukraine's armed forces. Unit-level operators tested and refined our field interfaces in active operational conditions, giving us direct feedback on what works under real mission pressure, not laboratory conditions.

Our team has worked alongside Ministry of Defence Ukraine engineers, participated in Brave1 — Ukraine's defense-tech accelerator — and built integrations with the Delta C2 system, Ukraine's national battlefield common operational picture. That experience informs every user interaction decision we make on field-deployed mobile software.

We understand the difference between software that passes acceptance testing and software that a unit commander actually reaches for under fire. Our design reviews include combat veterans who tell us when a feature is operationally unrealistic. That feedback loop is not available from standard commercial software vendors.

Why Corvus

There are mobile app studios and there are defense software vendors. We sit at the intersection — with the engineering discipline of the former and the operational understanding of the latter.

Field-Tested Credibility

Our software has been used by Ukraine MoD unit-level operators in active operational conditions. We know what field-deployed means — not in theory, but from direct feedback in the theatre.

Defense Domain Depth

Two-time NATO TIDE Hackathon winners. Brave1 members. Delta C2 integration experience. We understand COT, STANAG data models, and the interoperability requirements that commercial vendors typically ignore.

ISO-Certified Security Discipline

ISO 27001 certified. We apply defense-grade encryption, secure enclave key management, certificate pinning, and MASVS-aligned security controls on every mobile project we ship.

Frequently Asked Questions

What is tactical mobile app development?

Tactical mobile app development is the engineering discipline of building applications specifically for field operators — soldiers, first responders, survey teams, and special operations personnel — who work in adversarial environments: intermittent connectivity, extreme temperatures, gloved operation, and high-stress conditions. Unlike consumer mobile development, tactical apps prioritize offline-first data models, local encryption, rugged UI affordances, and integration with field hardware such as radios, ATAK-compatible devices, and sensors.

Do you build ATAK plugins?

Yes. We develop custom ATAK (Android Tactical Assault Kit) and TAK ecosystem plugins using the ATAK SDK. This includes map overlays, data feeds from external sensors or C2 systems, custom COT (Cursor-on-Target) message handlers, and UI panels surfaced inside the ATAK environment. We have experience connecting ATAK deployments to TAK Server instances and bridging data between ATAK and other COP platforms including Ukraine's Delta C2 system.

How do you handle offline-first with later sync?

Our offline-first architecture uses a local embedded database — SQLite or Realm — as the system of record on-device. All writes succeed locally first; a background sync engine queues changes and resolves conflicts when connectivity is restored. We use Protocol Buffers (Protobuf) for compact, schema-versioned payloads and gRPC or WebSocket channels for server sync. For map data, we pre-package MBTiles offline tile bundles so operators retain full map capability with zero network access. Conflict resolution strategies (last-write-wins, operational-priority merge, or custom domain logic) are defined during the data model design phase before any UI work begins.

What security standards do you follow for mobile?

We apply defense-grade security practices throughout the mobile development lifecycle. Data at rest is encrypted using AES-256 via platform-native secure enclave APIs (Android Keystore, iOS Secure Enclave). Data in transit is protected with TLS 1.3 and, where required, additional application-layer encryption with Protobuf-serialized payloads. We implement certificate pinning, jailbreak and root detection, tamper-evident logging, and remote wipe capabilities. Authentication uses PKCE-flow OAuth2 / OpenID Connect, integrable with Keycloak or DoD-compatible identity providers. Our processes are aligned with ISO 27001 controls and the OWASP Mobile Application Security Verification Standard (MASVS).
