(Strategic Takeaway) {#so-what} PP Calendar Reminders is an utilities app that is completely free. It holds a 4/5 rating from 10 reviews. > **Bottom Line:** The app's core lunar-tracking utility is currently locked behind launch-breaking bugs that have persisted for nearly two years, making stability the only priority that matters for retention. **Best for:** Users who require a calendar tool that integrates both Gregorian and Lunar dates for personal or professional scheduling. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit launch stability because users report immediate crashes on older operating systems → restore core utility ### Outlook: Declining The calendar utility market is consolidating around apps that offer frequent stability updates and modern widget support. PP Calendar Reminders remains in a maintenance-mode state that leaves it exposed to churn as users migrate to more reliable tools. - 🔴 The 23-month update gap prevents the app from supporting modern iOS standards, which directly causes the reported launch failures. - 🔴 User reports of immediate crashes on older operating systems indicate that the app is no longer functional for a portion of the base. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4/5 | | Total Reviews | 10 | | Sentiment | Upset (10/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **PP Calendar Reminders** (this app) | 4/5 | Upset | 金鹏 王 | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | 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:** 金鹏 王 ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/pp-calendar-reminders/id981158014?uo=4) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.9/5 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} ### Is PP Calendar Reminders free to use?
