ScanIn - FOSS Document Scanner

ScanIn is a Free and Open-source document scanner for Android and iOS. We've built ScanIn with privacy and security as the #1 priority. We've also introduced a set of novel features which are not available in the other document scanning apps.

What Made Us Develop ScanIn 🤔

As a result of COVID-19 pandemic - education, work and governance have migrated to Online. As students, we were asked to submit our homeworks, tests and notes as digital soft-copies. After the government imposed ban over CamScanner, we wanted a better open-source alternative which does not affect our privacy. So, we decided to develop ScanIn which is completely free and open source. We also analyzed the needs of students and working professionals and introduced some cool new features that are not even available with the paid alternatives.

Vision & Mission 💪

As FOSS lovers, our vision is to contribute to online education, remote work and governance by developing a restriction-less, fully featured and free document scanning application that can enable everyone to continue doing their jobs even during and post the pandemic. Our long term mission as a student-made startup is to make more such FOSS apps.

Idea Validation - Survey ✅

We always wanted ScanIn to be a 'Community based' application that was built based on the needs and feedbacks provided by a number of people. So, we decided to conduct a survey. We surveyed over 30 students along with a few working professionals. We asked them to prioritize their needs and to describe their problems while using the other alternative apps. We also got some valuable suggestions for new features. Based on the inferences, we decided the new features after analyzing the technical feasibility.

Novelties - What Makes Us Unique 💡

We've included some cool new features that make us stand out from the other alternatives. They're as follows :

• Protected PDF Generation : Produce password protected PDFs directly from ScanIn app.

• Credential Verification and QR : A QR code generated on the top corner of the document that can be scanned to validate the document.

• Custom Watermark : Place your own watermarks in the document.

• Add Page numbers : Automatically add page numbers to the pages in your document.

• Annotations : Annotate or highlight your document even after scanning.

• Warnings for potentially critical documents : ScanIn pops up a warning when you try to scan a critical document along with some safety measures.

• Protected safe folder : Place your important files into the safe folder to keep them private.

• Fully Open Source and Free : Proudly, ScanIn is fully open source and free.

• No APIs Used - Fully Offline : We've used zero APIs - as simple as that. The app can work offline.

• No Remote Databases or Backend services : We have not included any remote database to log any kind of details. We store everything only on an SQLite database locally.

Features Of ScanIn 🌟

• Edge detection : Automatically finds the edges of the document from a photo.

• Light weight : The total app size is just around 20MB.

• Fast and seamless : The scanning process is fast without lags.

• Document lighting filters : Low light? Just use a filter to make sure your document is visible.

• No Ads : We wanted to provide our users with the best experience. So, no space for annoying ads.

• User friendly UI with help screen : A simple and intuitive UI to make the scanning process seamless. We also guide the user with 'How to use' instructions during the first app run.
