(Strategic Takeaway) {#so-what} Birthday Calendar + is an established lifestyle app that is free with in-app purchases. It holds a 4.86/5 rating from 86.1K reviews. > **Bottom Line:** The app provides essential utility through reliable reminders, but the lack of maintenance on iOS creates a critical churn risk, so the PM must prioritize stability patches to prevent total loss of the long-term user base. **Best for:** Individuals seeking to organize personal contacts, track recurring events, and manage social reminders. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Rebuild iOS launch sequence because launch crashes are the top complaint → restore access for long-term users ### Feature Gaps vs Competitors - Native authentication sync (available in Minimalist Birthday Reminder) ### Outlook: Declining The category is consolidating around modern, stable tools that offer better OS integration and data portability. Birthday Calendar + is currently exposed due to its legacy iOS codebase, so the PM must shift focus from feature expansion to technical debt resolution to avoid losing the remaining user base to more reliable alternatives. - 🔴 iOS launch crashes prevent access to stored data, which drives negative sentiment and high churn among long-term users. - ⚪ Android updates continue to ship, but inconsistent notification delivery limits the effectiveness of the core reminder utility. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.86/5 | | Total Reviews | 86.1K | | Sentiment | Mixed (45/100) | | Confidence | High | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Birthday Calendar +** (this app) | 4.86/5 | Mixed | MobTouch Inc | | [Germany Calendar](https://marlvel.ai/apps/com-deventz-calendar-germany-g01) | N/A/5 | N/A | dEventz Studio | | [Vietnam Calendar](https://marlvel.ai/apps/com-deventz-calendar-vietnam-g01) | N/A/5 | N/A | dEventz Studio | | [Minimalist Birthday Reminder](https://marlvel.ai/apps/minimalist-birthday-reminder) | 4.7/5 | n/a | SHPAVDA, TOO | | [HBD 햅벋데 - 생일 캘린더 어플 공휴일 음력 달력](https://marlvel.ai/apps/hbd) | N/A/5 | N/A | yunji LEE | | [Tinder Dating App: Date & Chat](https://marlvel.ai/apps/tinder-dating-app-date-chat) | 4.2/5 | n/a | Tinder LLC | ## Company Profile - **Developer:** MobTouch Inc - **Website:** [https://www.birthdaycalendarapp.com](https://www.birthdaycalendarapp.com) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/birthday-calendar/id459270366?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=dev.cwolf.birthdaycalendar&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.birthdaycalendarapp.com) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*Germany Calendar*](https://marlvel.ai/apps/com-deventz-calendar-germany-g01) (dEventz Studio) · N/A Rating - [*Vietnam Calendar*](https://marlvel.ai/apps/com-deventz-calendar-vietnam-g01) (dEventz Studio) · N/A Rating - [*Minimalist Birthday Reminder*](https://marlvel.ai/apps/minimalist-birthday-reminder) (SHPAVDA, TOO) · 4.7/5 Rating - [*HBD 햅벋데 - 생일 캘린더 어플 공휴일 음력 달력*](https://marlvel.ai/apps/hbd) (yunji LEE) · N/A Rating - [*Tinder Dating App: Date & Chat*](https://marlvel.ai/apps/tinder-dating-app-date-chat) (Tinder LLC) · 4.2/5 Rating - [*Alarmy - Loud alarm clock*](https://marlvel.ai/apps/alarmy-loud-alarm-clock) (Delight Room Co., Ltd.) · 4.8/5 Rating | Positive Sentiment - [*Swiftime*](https://marlvel.ai/apps/swiftime) (MEDIANO Co.,Ltd.) · 4.5/5 Rating - [*Alarmie: Easy Rise Alarm Clock*](https://marlvel.ai/apps/alarmie-easy-rise-alarm-clock) (Jintian Wang) · 4.4/5 Rating - [*AlarmMon ( alarm clock )*](https://marlvel.ai/apps/alarmmon-alarm-clock) (Malang Studio Co.
