IntCall vs Voice changer with effects - **[Voice changer with effects](https://marlvel.ai/apps/voice-changer-with-effects)** by Baviux Apps & Games SL.: This app dominates the niche with over 1.4 million reviews, establishing it as the primary benchmark for user expectations in voice modulation. - **Key differences:** - Offers a massive library of pre-set voice filters that significantly outscales this app's current selection. - Provides a dedicated file management system for saved recordings, whereas this app lacks robust storage organization. - Supports direct sharing to social platforms with integrated audio-to-video conversion, a feature missing from this app. - **[MagicCall - Voice Changer App](https://marlvel.ai/apps/magiccall-voice-changer-app)** by Black N Green: MagicCall directly competes for the same prank-calling demographic by offering real-time voice modulation during active phone calls, mirroring our core value proposition. - **Key differences:** - Focuses heavily on background sound effects to simulate environments like concerts or traffic during calls - Utilizes a more aggressive monetization model centered on subscription-based access to premium voice filters ### Contenders (Strong Challengers) - **[Voice Changer - Audio Effects](https://marlvel.ai/apps/voice-changer-audio-effects)** by One Pixel Studio: Maintains high development velocity with two updates in the last six months, keeping feature parity tight. - Includes a built-in text-to-speech engine that allows users to generate voice effects from typed input. - Features a more aggressive ad-monetization strategy that gates advanced voice modulation presets behind rewarded video ads. - **[Metavoicer: Voice Changer AI](https://marlvel.ai/apps/metavoicer-voice-changer-ai)** by sabiha naznin: Metavoicer represents a shift toward AI-driven voice synthesis, threatening our market share by offering high-fidelity celebrity cloning that our current real-time filters lack. - Leverages generative AI to provide high-quality celebrity voice cloning unavailable in our current feature set - Includes a text-to-speech engine that allows users to generate custom audio clips without speaking ### Peers (What They Do Better) - **[Live Voice Changer - Prankcall](https://marlvel.ai/apps/live-voice-changer-prankcall)** by 晓溪 张: Targets the exact same prank-call use case as this app but currently lacks recent update activity. - Specializes in live-call voice modulation, directly competing with this app's core value proposition. - Users report the app's interface feels dated and lacks the modern design elements found in newer competitors. - **[Hair Clipper (Prank)](https://marlvel.ai/apps/hair-clipper-prank)** by Cuneyt Ayyildiz: While not a voice changer, it competes for the same 'prank app' entertainment budget and user attention span on mobile devices. - Utilizes device haptic feedback to simulate physical sensations, increasing the realism of the prank - Focuses on a single-purpose, high-engagement interaction model that is easier for casual users to grasp - **[Funcall - Voice Changer & Rec](https://marlvel.ai/apps/funcall-voice-changer-rec)** by bar ish shalom: Funcall overlaps with our core functionality by combining real-time voice changing with integrated call recording and international VOIP capabilities. - Includes native call recording functionality, allowing users to save and share their prank conversations - Features a demo call mode that lets users test voice effects before initiating a real call - **[Broken Screen Prank - Break it](https://marlvel.ai/apps/broken-screen-prank-break-it)** by 振山 董: Users report: This app is a dominant player in the broader prank category, capturing significant user time through visual deception rather than audio manipulation. - Maintains a massive user base through high-frequency updates and a vast library of visual effects - Uses a simple, one-tap activation UX that drives viral sharing and high retention rates ### New Kids on the Block (What's Innovative) - **[Voicemod](https://marlvel.ai/apps/voicemod)** by Voicemod Inc., Sucursal en Espana: Demonstrates extreme development velocity with 13 releases in the last six months, signaling a rapid expansion strategy. - Integrates a professional-grade soundboard that allows users to trigger custom audio clips during live sessions. - Leverages a cross-platform ecosystem that syncs voice profiles between mobile and desktop environments seamlessly. - **[Air Horn & Prank Sounds](https://marlvel.ai/apps/air-horn-prank-sounds)** by Boolean and Bean Pty Ltd: A new entrant that captures the 'quick prank' market segment with a focus on high-impact, short-duration sound effects. - Implements a 'sticky mode' for continuous sound playback, perfect for annoying friends in real-time - **[Voice Changer・Generator Pro](https://marlvel.ai/apps/changervoice-app)** by Julian Ciobanu: This newcomer combines real-time modulation with AI-based voice generation, directly challenging our feature roadmap. - Aggressively shipping updates to include celebrity-style voice presets and custom generation tools ## What's New - **Latest (v5.0.1, 3 months ago):** Maintenance update focused on bug fixes and performance improvements. ## App Momentum (Maintenance) {#momentum} - Ships maintenance updates only - No major feature expansion > **Cadence:** 2 total versions · 1 majors in last 6 months · 111 days since last update · 6 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Call Voice Changer - IntCall is an entertainment app. With a 3.97/5 rating from 29.8K reviews, it shows mixed user reception. > **Bottom Line:** The app's real-time VOIP integration is a defensible differentiator, but the current technical instability and credit-based friction are eroding the user base. Prioritizing core call stability will unlock higher retention, as the current churn is driven by functional failures rather than a lack of market interest. **Best for:** Users seeking prank-calling tools and entertainment-focused voice modulation for social interactions. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship a demo-call mode because users report confusion regarding feature operation → increase conversion ### Feature Gaps vs Competitors - Offline recording management (available in Voice changer with effects but missing here) ### Outlook: Declining The prank-calling market is consolidating around apps that offer either high-fidelity AI synthesis or seamless, ad-supported UX. Call Voice Changer - IntCall's maintenance-only cadence leaves it exposed to faster-moving rivals, and the current technical failures will continue to compress the user base until core stability is addressed. - 🔴 Persistent technical instability and crashes during active calls erode the daily active habit, compounding the rating drag already visible on Android. - 🔴 The credit-based monetization model creates friction that drives negative sentiment, as users perceive the cost as prohibitive for casual prank usage. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.97/5 | | Total Reviews | 29.8K | | Sentiment | Mixed (45/100) | | Confidence | High | | Pricing Model | Subscription | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Call Voice Changer - IntCall** (this app) | 3.97/5 | Mixed | Astra Communication LTD | | [Voice Changer・Generator Pro](https://marlvel.ai/apps/changervoice-app) | 4.5/5 | N/A | Julian Ciobanu | | [Voice changer with effects](https://marlvel.ai/apps/voice-changer-with-effects) | 4.7/5 | Thrilled | Baviux Apps & Games SL. | | [Voice Changer - Audio Effects](https://marlvel.ai/apps/voice-changer-audio-effects) | 4.6/5 | N/A | One Pixel Studio | | [Voicemod](https://marlvel.ai/apps/voicemod) | 4.7/5 | N/A | Voicemod Inc., Sucursal en Espana | | [Hair Clipper (Prank)](https://marlvel.ai/apps/hair-clipper-prank) | 4.5/5 | N/A | Cuneyt Ayyildiz | ## Company Profile - **Developer:** Astra Communication LTD - **Website:** [https://www.astracom.net/call-voice-changer](https://www.astracom.net/call-voice-changer) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/call-voice-changer-intcall/id535048805?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.soundeffecttools.voiceavatar.changer&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.astracom.net/call-voice-changer) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Voice Changer・Generator Pro*](https://marlvel.ai/apps/changervoice-app) (Julian Ciobanu) · 4.5/5 Rating - [*Voice changer with effects*](https://marlvel.ai/apps/voice-changer-with-effects) (Baviux Apps & Games SL.) · 4.7/5 Rating | Excellent Sentiment - [*Voice Changer - Audio Effects*](https://marlvel.ai/apps/voice-changer-audio-effects) (One Pixel Studio) · 4.6/5 Rating - [*Voicemod*](https://marlvel.ai/apps/voicemod) (Voicemod Inc., Sucursal en Espana) · 4.7/5 Rating - [*Hair Clipper (Prank)*](https://marlvel.ai/apps/hair-clipper-prank) (Cuneyt Ayyildiz) · 4.5/5 Rating - [*Funcall - Voice Changer & Rec*](https://marlvel.ai/apps/funcall-voice-changer-rec) (bar ish shalom) · 3.4/5 Rating - [*Live Voice Changer - Prankcall*](https://marlvel.ai/apps/live-voice-changer-prankcall) (晓溪 张) · 4.4/5 Rating - [*Broken Screen Prank - Break it*](https://marlvel.ai/apps/broken-screen-prank-break-it) (振山 董) · 4.5/5 Rating | Positive Sentiment - [*MagicCall - Voice Changer App*](https://marlvel.ai/apps/magiccall-voice-changer-app) (Black N Green) · 3.4/5 Rating - [*Metavoicer: Voice Changer AI*](https://marlvel.ai/apps/metavoicer-voice-changer-ai) (sabiha naznin) · 4.3/5 Rating ## Frequently Asked Questions {#faq} ### Is Call Voice Changer - IntCall free to use?
