Shipped minor performance optimizations. - Last major release Mar 2026. > **Cadence:** 5 total versions · 2 majors in last 6 months · 80 days since last update · 1 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} PDF Voice Reader TTS Audiobook is a book app that is completely free. With a 4.35/5 rating from 131 reviews, it shows mixed user reception. > **Bottom Line:** PDF Voice Reader TTS Audiobook must prioritize core TTS engine stability, as parsing failures render the primary value proposition unusable for a significant user segment. Addressing these technical regressions will stabilize the daily active habit before the app loses its foothold to high-fidelity AI rivals. **Best for:** Students, professionals, and readers who require accessibility tools to convert static documents into audio format. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Rebuild TTS parsing logic because non-Latin script failures are the top complaint → reduce churn ### Feature Gaps vs Competitors - Proprietary AI voice generation (available in ElevenReader but absent here) ### Outlook: Mixed The document-utility market is consolidating around AI-powered narration, and PDF Voice Reader TTS Audiobook's reliance on standard TTS engines leaves it exposed to churn. Unless the team addresses parsing regressions and adds granular navigation, the app will likely lose its casual user base to rivals with superior voice quality. - 🔴 Persistent text-to-speech parsing failures for non-Latin scripts erode user trust, which compounds the churn pressure from high-fidelity AI rivals. - ⚪ The current maintenance-only update cadence fails to address core utility gaps, leaving the app vulnerable to competitors with rapid feature deployment. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.35/5 | | Total Reviews | 131 | | Sentiment | Mixed (55/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **PDF Voice Reader TTS Audiobook** (this app) | 4.35/5 | Mixed | Vladislav Alikov | | [Dyve-](https://marlvel.ai/apps/sunnook-library-dyves) | 5.0/5 | N/A | Maha Nater | | [PDF Reader-All Document Viewer](https://marlvel.ai/apps/com-ai-pdf-reader-android-app-year2026) | 3.3/5 | N/A | rora Apps | | [Rememberly - Save highlights](https://marlvel.ai/apps/app-getrememberly-rememberly) | N/A/5 | N/A | Chandima Bandara | | [Linkpack](https://marlvel.ai/apps/linkpack) | 4.3/5 | Mixed | PZ Mobile Limited | | [LiquidText Prepaid](https://marlvel.ai/apps/liquidtext-prepaid) | 4.7/5 | Mixed | LiquidText, Inc. | ## Company Profile - **Developer:** Vladislav Alikov - **Website:** [https://fuza.fun/](https://fuza.fun/) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/pdf-voice-reader-tts-audiobook/id6747906903?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.digitalstorm.reader&hl=en&gl=us) - **Dev Site:** [Official Website](https://fuza.fun/) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Dyve-*](https://marlvel.ai/apps/sunnook-library-dyves) (Maha Nater) · 5.0/5 Rating - [*PDF Reader-All Document Viewer*](https://marlvel.ai/apps/com-ai-pdf-reader-android-app-year2026) (rora Apps) · 3.3/5 Rating - [*Rememberly - Save highlights*](https://marlvel.ai/apps/app-getrememberly-rememberly) (Chandima Bandara) · N/A Rating - [*Linkpack*](https://marlvel.ai/apps/linkpack) (PZ Mobile Limited) · 4.3/5 Rating - [*LiquidText Prepaid*](https://marlvel.ai/apps/liquidtext-prepaid) (LiquidText, Inc.) · 4.7/5 Rating - [*Web to PDF Converter Pro*](https://marlvel.ai/apps/web-to-pdf-converter-pro) (Javid Multani) · 2.0/5 Rating - [*PDF Highlighter : PDF & Photos*](https://marlvel.ai/apps/pdf-highlighter-pdf-photos) (Jaydeep Dhameliya) · 3.0/5 Rating - [*Speechy text to speech reader*](https://marlvel.ai/apps/speechy-text-to-speech-reader) (Arthur Eduardo Skaetta Alvarez Desenvolvimento de Software LTDA.) · 4.5/5 Rating - [*Speech-Flow: Text to Speech*](https://marlvel.ai/apps/speech-flow-text-to-speech) (Nikita Chizhov) · 3.7/5 Rating - [*Paperpile*](https://marlvel.ai/apps/paperpile) (Paperpile LLC) · 4.5/5 Rating | Positive Sentiment ## Frequently Asked Questions {#faq} ### Is PDF Voice Reader TTS Audiobook good for reading non-English documents?
