No major feature updates since 2024 - Maintenance-only cadence for two years > **Cadence:** 1 total versions · 1 majors in last 6 months · 865 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Roster-Calendar is a market-leading productivity app. With a 4.37/5 rating from 63 reviews, it delivers strong user satisfaction. > **Bottom Line:** Roster-Calendar's reliance on manual entry is a liability in a market where sync is expected, and fixing data persistence is the only way to stop the current churn trend. **Best for:** Shift workers requiring rapid calendar entry and documentation of work hours. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit data persistence logic because users report saved shifts disappear after navigation → stabilize retention ### Feature Gaps vs Competitors - Direct sync engine (available in CalenGoo but missing here) ### Outlook: Declining The shift-scheduling market is consolidating around tools that offer seamless multi-device sync, leaving Roster-Calendar's manual-entry model increasingly isolated. Without a pivot to address stability and synchronization, the app will continue to lose its remaining user base to more reliable competitors. - 🔴 Data persistence regressions in the latest release erode user trust, which compounds the churn pressure from aggressive ad placement. - 🔴 The maintenance-only release cadence over the last two years allows rivals to capture the professional segment with superior sync capabilities. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.37/5 | | Total Reviews | 63 | | Sentiment | Excited (65/100) | | Confidence | Medium | | Pricing Model | Subscription | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Roster-Calendar** (this app) | 4.37/5 | Excited | michael heinz | | [FormConnect Pro](https://marlvel.ai/apps/com-formconnections-formconnectpro) | 4.6/5 | Mixed | FormConnections, Inc. | | [CalenGoo - Calendar and Tasks](https://marlvel.ai/apps/com-calengoo-android) | 4.9/5 | Mixed | Gunia UG (haftungsbeschränkt) | | [DayBlocks - Visualize Time](https://marlvel.ai/apps/com-davensix-dayblocks) | 5.0/5 | N/A | ALAN D NAVARRO LOPEZ | | [WidgetCal-Calendar Widget](https://marlvel.ai/apps/widgetcal-calendar-widget) | 3.6/5 | n/a | YunaSoft Inc. | | [ShiftCal: Shift Schedule Maker](https://marlvel.ai/apps/shiftcal-shift-schedule-maker) | 5.0/5 | N/A | nguyen thanh | ## Company Profile - **Developer:** michael heinz - **Website:** [https://www.lifegrit.com](https://www.lifegrit.com) ## Data Sources & Links - **App Store ID:** 536118948 - **Dev Site:** [Official Website](https://www.lifegrit.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*FormConnect Pro*](https://marlvel.ai/apps/com-formconnections-formconnectpro) (FormConnections, Inc.) · 4.6/5 Rating - [*CalenGoo - Calendar and Tasks*](https://marlvel.ai/apps/com-calengoo-android) (Gunia UG (haftungsbeschränkt)) · 4.9/5 Rating - [*DayBlocks - Visualize Time*](https://marlvel.ai/apps/com-davensix-dayblocks) (ALAN D NAVARRO LOPEZ) · 5.0/5 Rating - [*WidgetCal-Calendar Widget*](https://marlvel.ai/apps/widgetcal-calendar-widget) (YunaSoft Inc.) · 3.6/5 Rating - [*ShiftCal: Shift Schedule Maker*](https://marlvel.ai/apps/shiftcal-shift-schedule-maker) (nguyen thanh) · 5.0/5 Rating - [*Wishlist: Smart Wish Tracker*](https://marlvel.ai/apps/wishlist-smart-wish-tracker) (Noman.Sheikh) · N/A Rating - [*Solid Calendar*](https://marlvel.ai/apps/solid-calendar) (Solid Apps S.R.L.) · 4.9/5 Rating - [*Time Doctor*](https://marlvel.ai/apps/time-doctor) (Mystaff.com LLC) · 2.8/5 Rating - [*SIGNL4 - Mobile Alerting*](https://marlvel.ai/apps/signl4-mobile-alerting) (Derdack GmbH) · 4.5/5 Rating | Positive Sentiment - [*Curo: More doing*](https://marlvel.ai/apps/curo-more-doing) (KIA LABS LLC) · 5.0/5 Rating | Excellent Sentiment ## Frequently Asked Questions {#faq} ### Is Roster-Calendar good for shift workers?
