Work where the coffee is — no connectivity required

iOS and Android apps for field agents, warehouse operators, and producer registration teams. Full offline capability with deferred sync, so data capture never waits on connectivity.

01 · Context

Coffee operations happen where mobile coverage doesn't

A producer's plot in Yirgacheffe might have no bars. A remote washing station in Kaffa might have WiFi for twenty minutes at lunch. If your software requires connectivity to capture data, field operations devolve into paper forms and 9pm-at-the-office data entry sessions where last week's information gets guessed back into reality. BunnaLink Mobile Apps solve this by making offline a first-class mode from day one — not an afterthought retrofit.

02 · Capabilities

What you get

Producer registration

Capture new producer profiles in the field with photo, ID, phone, next-of-kin, consent. No paper forms, no re-keying on Monday morning.

GPS polygon capture

Walk a plot boundary, record the polygon, link to producer — all offline. Polygons validate automatically on sync against altitude and boundary rules.

Cherry intake

Weigh, grade, price, log supplier and delivery mode. Producer balance updates when the phone syncs. No separate reconciliation needed.

Stock movement

Warehouse transfers and adjustments from the phone with barcode scanning. Same audit log as web-based operations, same approval workflow.

Deferred sync with conflict resolution

Everything captured offline syncs back intelligently when coverage returns. Rare conflicts surface with clear resolution options; most cases auto-resolve.

03 · Process

How it works

01

Agent logs in and downloads

On WiFi or cellular, the app downloads the agent's assigned producers and recent transactions. Local database ready for offline operation.
02

Works in the field, offline

Register new producers, capture polygons, log deliveries. All data stored locally, encrypted on-device. Agent sees real running balances.
03

Syncs when back in coverage

Background sync when the phone reconnects. Server merges changes, resolves conflicts, updates the central database. Agent sees sync status clearly.
04

HQ reviews what synced

Flagged conflicts (rare — less than 1% of transactions) land in a review queue. Most syncs require zero HQ intervention.

ተደጋግመው የሚጠየቁ ጥያቄዎች

How long can the app operate offline?

Effectively indefinitely. We've tested 3+ weeks of continuous offline use without data loss. The practical limit is phone storage (typically 50-500MB depending on assigned data volume).

How much phone storage does it use?

Roughly 50MB for the app binary plus 10-50MB of local data depending on the number of producers assigned to the agent and how many transactions are cached locally.

What iOS and Android versions are supported?

iOS 14+ and Android 9+ fully supported. Tested regularly on the most common low-end Android devices used in Ethiopian field operations.

What happens if the phone is lost or stolen?

All local data is encrypted at rest. Unauthorized login attempts trigger a remote wipe after threshold. An agent's assigned producers can be reassigned to another device within minutes from the web admin.
