App Showcase: Tiny Doc

What it does

Tiny Doc is a comprehensive document scanner and management tool for mobile. The app allows users to either scan documents using their camera or import existing files. Once digitized, documents can be manipulated through a powerful suite of tools, including OCR for text extraction, translation, highlighting, e-signatures, and watermarking. It also provides robust file management features like folder organization, renaming, and secure sharing.

Where it shines

The app's strength lies in its extensive post-scan editing capabilities. It moves beyond simple scanning to become a true document workflow tool. At 02:34, the user effortlessly draws, places, and resizes a signature, demonstrating a fluid e-signature process. The watermark feature, shown at 02:51, offers a live preview with granular controls for opacity and spacing, which is a professional touch. The flexibility to import existing files (00:41) or scan new ones makes it a versatile hub for all documents.

UX highlights

• Dual-Mode Signatures: At 02:18, the app offers the choice to either draw a signature or scan one from paper, catering to different user preferences for convenience and authenticity.
• Live Watermark Preview: While adjusting the watermark settings (02:51), the user sees the changes reflected on the document in real-time, making a complex task intuitive.
• Fluid Page Management: Reordering document pages is done with a simple and responsive drag-and-drop interaction (01:44), which feels natural.
• Clear Batch Operations: The batch processing screen (03:25) neatly organizes options like color filtering and page size, making it easy for users to apply changes to multiple pages at once.
• Contextual OCR: The OCR tool not only extracts text but immediately offers translation and copy options (00:56), anticipating the user's next step.

Monetization & growth

Tiny Doc employs a paywall-first strategy, presenting a subscription offer immediately upon the first launch (00:00). The offer is a 3-day free trial that converts to a weekly plan, a common tactic to lower the initial barrier to entry while securing payment details. The paywall itself focuses on value-stacking, with a long, scrolling list of all the features unlocked with a premium plan. After some initial app usage, a native rating prompt appears (00:35) to encourage positive App Store reviews.

Who it’s for

This app is well-suited for professionals, small business owners, and students who regularly handle paperwork and need more than just a basic scanner. Its advanced features like e-signatures, watermarking, and OCR with translation are targeted at users who need to process, annotate, and secure documents on the go. The comprehensive toolset makes it a viable mobile alternative to desktop PDF software for many common tasks.

Notes & opportunities

While functionally powerful, the app's user interface adheres closely to standard iOS design patterns, which makes it feel familiar but lacks a distinct brand personality. The immediate paywall at launch (00:00) could be a point of friction, potentially causing some users to drop off before they can experience the app's capabilities. A short, interactive demo of a single powerful feature, like OCR, before presenting the paywall could improve conversion by demonstrating value first.
