The developer is now prioritizing store-page messaging to address user confusion regarding the app's purpose. **Overall trend**: Mixed **Compared at**: 2026-09-01 ### High-impact changes - **[Shifted] Outlook Trend** (positioning) ### Medium-impact changes - **[Added] OS-Level Threat Identification** (swot) - **[Added] Localized Messaging Opportunity** (swot) - **[Shifted] PM Action Item Focus** (positioning) ## What's New - **Latest (v1.9.0, 2 weeks ago):** General stability improvements. - **Last Major (v1.0.2, 7 months ago):** Expanded international reach with the addition of Japanese and Korean language support. ## App Momentum (Maintenance) {#momentum} - Ships minor stability updates quarterly. - Added Japanese and Korean support recently. > **Cadence:** 2 total versions · 1 majors in last 6 months · 14 days since last update · 217 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Fill Storage Pro is a market-leading utilities app that is free with in-app purchases. With a 4.27/5 rating from 1.8K reviews, it delivers strong user satisfaction. > **Bottom Line:** Stability failures during storage filling erode the utility's value proposition, causing system-level crashes that frustrate the core developer audience. Addressing these crashes would unlock higher retention, as the current stability issues currently overshadow the app's functional utility. **Best for:** iOS and Android developers, testers, and privacy-conscious users needing to manage or simulate device storage conditions. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit storage-filling logic because system crashes and reboots are the top complaint theme -> reduce negative sentiment ### Outlook: Mixed The utility market for storage simulation is consolidating as OS-level tools improve, leaving Fill Storage Pro exposed to technical instability. Unless the developer resolves the reported crash patterns, the app will continue to struggle with negative sentiment from users who misunderstand its purpose. - 🔴 System crashes during storage filling erode the daily active habit, which compounds the rating drag already visible on Android. - ⚪ The latest release focused on stability improvements, but the maintenance-mode cadence limits the ability to address complex hardware-specific bugs. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.27/5 | | Total Reviews | 1.8K | | Sentiment | Excited (75/100) | | Confidence | High | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Fill Storage Pro** (this app) | 4.27/5 | Excited | Arum Communications Corp. | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.8/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | ## Company Profile - **Developer:** Arum Communications Corp. - **Website:** [https://arumcomm.blogspot.com/](https://arumcomm.blogspot.com/) - **Social:** [Facebook](https://www.facebook.com/recover/initiate?lwv=110) ## Data Sources & Links - **App Store ID:** 6755057653 - **Google Play ID:** com.arumcomm.fillstorage - **Dev Site:** [Official Website](https://arumcomm.blogspot.com/) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating - [*로또 황금번호 생성기*](https://marlvel.ai/apps/lotto-lottogold) (jaehwan lee) · N/A Rating - [*도사폰 (만세력 역학도구)*](https://marlvel.ai/apps/app--656) (Softchaser Company Limited) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Does Fill Storage Pro increase my phone's storage capacity?
