The MonivioScan expense list with demo data for Štúdio Lipa s. r. o., iPhone on the left and Android on the right: Papier & Co. for €86.10, marked Processed, then Čerpacia stanica Sever, Cloud Office and Bistro Záhrada, each with a document thumbnail, category, date and amount. — The same expense list on iPhone and Android, each app with its own platform's controls. Demo data.

Reviewing a scanned document with demo data on iPhone and Android: 1 page, 1 document, a preview of the Papier & Co. invoice, a Scan more pages button, the organisation picker set to Štúdio Lipa s. r. o. and a Send all (1) button. — Every document is reviewed before it is sent: you can add a page and choose the company it belongs to.

Filing three expenses at once with demo data on iPhone and Android: categories such as Auto, Pohonné hmoty (fuel), Kancelárske potreby (office supplies) and Softvér, the tags Projekt Alfa, Služobná cesta and Marketing, and on Android a File (3) button. — Three expenses get a category and tags at once, without opening each one.

In short

A pile of pages becomes finished documents
Sending doesn't wait for a signal
Recognised text stays on the phone
Two native apps, one behaviour

The brief

MonivioScan is a mobile app for iPhone and Android that scans receipts and invoices, groups the pages into documents and sends them to Monivio, where they become expenses. Uploads run in the background, so the phone can be locked right away. For Monivio, an invoicing app for sole traders and companies, we built two native apps with the same scope. The Android app is on Google Play; the iPhone app is awaiting App Store approval.

MonivioScan is a mobile app we built twice for Monivio: natively for iPhone and natively for Android. A receipt or an invoice turns up where the money is spent, and at that moment people have a phone to hand, not a computer. So the app does one thing well: it scans the document, lets you check it and sends it to the right company in Monivio as an expense.

What we did

A pile of pages becomes finished documents

Receipts and invoices can be scanned one after another, and the app splits the pages into documents by itself. It only suggests joining pages, and only neighbouring ones, for example by a page marker or a shared document number. A suggestion nobody confirms does not apply, and the pages stay separate. Before sending, everything sits on a review screen where you can scan another page and pick the company.

Sending doesn't wait for a signal

Once a document is sent, the phone can be locked. Documents upload in the background with the tools each system provides for it, and if the connection drops, the upload retries by itself. Anyone saving mobile data can switch uploads to Wi-Fi only. Every document carries its own key, so even a repeated attempt never creates the same expense in Monivio twice.

Recognised text stays on the phone

To pair pages correctly, the app recognises page markers, company IDs and the QR code from Slovakia's eKasa receipt system right on the phone. The recognised text never leaves the device: Monivio receives the document as an image or PDF, plus the contents of the QR code. The app has no ads and no advertising ID. On Android it does not even need camera access, because the scanner runs in Google Play services.

Two native apps, one behaviour

The original plan was a single shared app in React Native or Flutter. We built two native apps instead: for iPhone in Swift and SwiftUI with the VisionKit scanner, for Android in Kotlin and Jetpack Compose with the ML Kit scanner. Each looks and behaves like the other apps on that phone. The page-pairing rules are checked against the same test cases on both platforms, so a document comes out the same on iPhone and on Android.

What does this mean for your project?

A company's mobile app doesn't have to do everything its web app does. MonivioScan does the one thing people reach for their phone for: it scans a document, pairs the pages, uploads it in the background and never sends anything twice. We built it natively for iPhone and Android, with the same scope and with page-pairing rules checked by the same tests on both platforms. The details you don't see at first glance made the difference: what happens without a signal, what stays on the phone and what the app sends on. If you have a web app and your people in the field need to use it from a phone, we'll start with the step they take most often.
