App Showcase: TBR - Bookshelf

What it does

TBR - Bookshelf is a mobile app designed for readers to track their literary journeys. Its core function is to allow users to search for books, add them to various lists like 'To Be Read' (TBR) or 'Read', and log their reading progress. The app goes beyond simple tracking by offering a detailed rating system, personal notes, and the ability to create and manage multiple custom bookshelves.

Where it shines

The app shines in its detailed and engaging approach to book rating. At 00:43, after finishing a book, the user isn't just presented with a 5-star scale. Instead, they can rate the book on unique axes like predictability, interest, and even how much it made them cry, using playful icons. Another strength is its robust customization. After upgrading to Pro, the user can personalize their virtual bookshelf with different themes and decorative plants (02:51), which fosters a strong sense of ownership and makes the experience fun.

UX highlights

• Contextual Tooltips: Instead of a tutorial, the app introduces new functionality with contextual pop-ups, like the 'Half Stars' feature notice at 00:38.
• Granular Rating System: The use of multiple, icon-based sliders for ratings makes reviewing a book more nuanced and interactive.
• Flexible Bookshelf Management: Users can create, rename (10:54), and delete multiple custom bookshelves, allowing for personalized organization beyond a single TBR list.
• Manual Entry with Photo Upload: For books not in the database, the manual add flow (07:38) is simple and includes the option to upload a custom cover from photos (07:57).
• Visual Goal Tracking: The 'Reading Goal' screen (11:52) provides a clear, visual representation of progress, which is motivating for users.
• Clean and Uncluttered UI: The main interface is straightforward, prioritizing search and list management without unnecessary distractions.

Monetization & growth

Monetization is handled through a Pro subscription, triggered by a soft paywall. When a user tries to access a premium feature like 'Add Quote' (01:59), a paywall appears. The paywall itself, seen at 02:02, presents multiple plans including a monthly, 6-month, and yearly option with a '50% off' deal highlighted. It also includes a 'Special Offer' for a lifetime subscription. This multi-pronged approach caters to different levels of user commitment. After subscribing, the app immediately unlocks all features, including extensive cosmetic customizations.

Who it’s for

This app is clearly designed for avid readers who want more than a simple checklist. Its target users are likely those who enjoy journaling, curating lists, and reflecting on their reading experience. The detailed rating system and bookshelf organization cater to 'power readers' who might manage book club lists, research for projects, or simply enjoy categorizing their library by genre, mood, or priority. The playful customization options also appeal to users who value aesthetics and personalization in their digital tools.

Notes & opportunities

The immediate system prompt for notifications at 00:01 without a warm-up screen could be jarring for some users and might lead to a lower opt-in rate. Adding a brief screen explaining the benefit of notifications could improve this. Additionally, while the detailed rating system is a strength, the 'Predictability' metric (00:44) could be ambiguous; clarifying what a high or low score means would add clarity. Finally, the app could further leverage its rich rating data to offer users personalized stats and insights, such as 'You tend to enjoy books with a high tear rating and low predictability.'
