The lack of updates since August 2023 positions the app as a legacy tool rather than a competitive modern solution. ## Monetization Strategy - **Model:** Paid - **Tiers:** Single purchase at $4.99 - **Price:** iOS: $4.99 - **Analysis:** The $4.99 one-time purchase model is currently misaligned with the app's lack of updates and functional gaps. ## 🔴 User Sentiment (Medium Confidence: 4 of 4 reviews analyzed) {#user-sentiment} - **Overall Rating:** 1/5 - **Platform Split:** iOS 1.0/5 (2 ratings) - **Overall Sentiment:** Upset ### Top Complaints (Impact Areas) - **Lack of granular grade management prevents teachers from assigning weighted values to different course assignments** ## SWOT Analysis {#swot} **Core Strengths:** - Core grade-tracking utility provides a baseline for class management **Growth Levers:** - Introduce weighted grading logic to capture the segment of teachers requiring accurate final mark calculations ## What's New - **Latest (v1.2.2, 3 years ago):** General bug fixes and stability improvements. ## App Momentum (Zombie) {#momentum} - No major updates since August 2023. - Development appears to be in maintenance. > **Cadence:** 1 total versions · 0 majors in last 6 months · 1132 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Grade Book is an education app that is a paid app. It holds a 1/5 rating from 2 reviews. > **Bottom Line:** Restoring data integrity and adding weighted grading would address the functional failures currently driving negative sentiment. Without these changes, the app remains a legacy tool that cannot compete with modern academic management software. **Best for:** Teachers and educators in school or university settings. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit data migration logic because users report student records shifting between classes -> restore data integrity ### Outlook: Declining The academic software market is shifting toward integrated, cloud-synced solutions that handle complex weighted grading. Grade Book's failure to update since 2023 leaves it exposed to churn, as teachers migrate to tools that maintain data integrity and provide active support. - 🔴 The lack of updates since August 2023 indicates the app is in maintenance mode, which prevents it from addressing critical user-reported bugs. - 🔴 Data integrity failures cause student records to shift unexpectedly, which destroys the user's trust in the app as a reliable grade-keeping tool. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 1/5 | | Total Reviews | 2 | | Sentiment | Upset (15/100) | | Confidence | Medium | | Pricing Model | Paid | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Grade Book** (this app) | 1/5 | Upset | Piet Jonas | | [Catbus Student](https://marlvel.ai/apps/catbus-student) | 4.3/5 | N/A | Cohota Join Stock Company | | [Money Matrix (CAD)](https://marlvel.ai/apps/money-matrix-cad) | 5.0/5 | N/A | Blooming Kids Software LLC | | [Quran Treasure Island for Kids](https://marlvel.ai/apps/quran-treasure-island-for-kids) | 4.9/5 | Mixed | Akeela Manekia | | [Valencia College - MyVC](https://marlvel.ai/apps/valencia-college-myvc) | 5.0/5 | N/A | Valencia College | | [Verbi: Learn a New Language](https://marlvel.ai/apps/verbi-learn-a-new-language) | 4.3/5 | n/a | ACADIA LABS INC. | ## Company Profile - **Developer:** Piet Jonas - **Website:** [https://gradebook.speedymarks.com](https://gradebook.speedymarks.com) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/grade-book/id307247665?uo=4) - **Dev Site:** [Official Website](https://gradebook.speedymarks.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Catbus Student*](https://marlvel.ai/apps/catbus-student) (Cohota Join Stock Company) · 4.3/5 Rating - [*Money Matrix (CAD)*](https://marlvel.ai/apps/money-matrix-cad) (Blooming Kids Software LLC) · 5.0/5 Rating - [*Quran Treasure Island for Kids*](https://marlvel.ai/apps/quran-treasure-island-for-kids) (Akeela Manekia) · 4.9/5 Rating - [*Valencia College - MyVC*](https://marlvel.ai/apps/valencia-college-myvc) (Valencia College) · 5.0/5 Rating - [*Verbi: Learn a New Language*](https://marlvel.ai/apps/verbi-learn-a-new-language) (ACADIA LABS INC.) · 4.3/5 Rating - [*자주 틀리는 우리말*](https://marlvel.ai/apps/app--424) (DaolSoft, Co., Ltd.) · N/A Rating - [*달공부 - 한 달 공부 다이어리 + 루틴/공부 타이머*](https://marlvel.ai/apps/azlabs-dalstudy) (SuWon Choi) · N/A Rating - [*타요콘 - 타요 아바타 놀이동화*](https://marlvel.ai/apps/com-kigle-project-tayocon) (KIGLE) · 3.1/5 Rating - [*천자문 워치*](https://marlvel.ai/apps/app--385) (kim juyoung) · N/A Rating - [*천자문 공부 도우미*](https://marlvel.ai/apps/app--382) (kim juyoung) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Grade Book suitable for university-level grading?
