(Strategic Takeaway) {#so-what} Date Converter: Calendars is an utilities app that is free with in-app purchases.

Date Converter: Calendars remains exposed due to its recent navigation regression, which forces users to abandon the app for more efficient alternatives. - 🔴 The latest update's navigation regression increases time-to-task, which erodes the utility for power users who rely on the app for frequent comparisons. - ⚪ The maintenance-only release cadence suggests a lack of active investment, leaving the app vulnerable to competitors that prioritize fluid, modern date-selection workflows. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.44/5 | | Total Reviews | 102 | | Sentiment | Mixed (45/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 2 analyzed | | Trend | Mixed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Date Converter: Calendars** (this app) | 4.44/5 | Mixed | TenTal | | [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:** TenTal - **Website:** [https://www.tental.net](https://www.tental.net) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/date-converter-calendars/id382423257?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.arytbk.dateconverter&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.tental.net) - **Sources:** Developer website content, 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} ### Is Date Converter: Calendars accurate for historical research?
