What they wish it did
Capabilities people described needing that Sling does not give them, taken from the highest-scoring problems first. These are individual accounts written in each person’s own terms, so two entries may describe the same underlying gap in different words.
- Reliable mobile scheduling app with full functionality and responsive support
- Reliable notification system with delivery confirmation
- Stable user interface without blank pop-ups
- A scheduling app that doesn't freeze or require rebooting to function
- Reliable cross-platform chat app that doesn't require frequent reinstalls
- Reliable scheduling software that prevents date errors and validates inputs
- A mobile scheduling app that ensures all UI elements are functional and menus are fully populated
- Responsive UI that adapts to device status bar and notch areas, ensuring all controls are accessible
- Stable app with persistent notification delivery that does not require resets
- A reliable push notification service that delivers messages instantly without requiring the user to open the application.
- A feature to add notes or details to existing shifts without triggering approval workflow
What they do instead
The manual processes people built around the gap. A long workaround list is the strongest evidence a problem is real: someone is already paying for it in time. Where several people described the same workaround, it is marked.
- uses desktop to create or edit schedules because app cannot do so
- missed messages from manager
- can't see shift selection
- reboots device to try to fix the frozen app
- reinstall app multiple times a week
- Manually checking and correcting shift dates due to glitches
- struggles to toggle picture feature due to UI placement
- resets the app every few months to fix notifications
- open the app to get the messages
- Adding info to a shift necessitates a new shift request

Read this fairly
These are complaints, and only complaints — nobody posts to say their software worked. A high count mostly reflects how many people use Sling at all, so this page is not a quality judgement and should not be read as one. What it is good for is the shape of the gaps: the specific jobs people could not get done, which are the same whether the tool is popular or not.
