Sling Scheduling Review: Features, Pricing, Pros & Cons
Sling's free plan covers 30 users. But is it enough? Honest review of features, pricing ($0-$3.40/user), and where it falls short.

49,500 people search for "sling scheduling" every month. That's more than When I Work, Deputy, and 7shifts combined.
There's a reason for that. Sling has one of the most generous free plans in the scheduling space: up to 30 users, shift scheduling, team messaging, and time-off requests. No credit card. No trial period. Just free.
But free has limits. And the jump from free to paid changes the math. Here's what you're actually getting, what you're not, and whether it's worth paying for.

Sling Free works for 25 employees if you don't need time tracking. Once you do, Turnozo includes everything for one price.

The free plan is genuinely useful. 30 users is enough for most small restaurants, retail shops, and cafes. You get real scheduling (not just a shared calendar), shift templates, time-off management, and team messaging. That's more than Homebase or Connecteam offer for free. (For a full comparison of alternatives, see our Sling alternatives breakdown.)
Messaging is built in. Direct messages, group chats, and a team newsfeed. You don't need a separate WhatsApp group or Slack workspace. For shift-based teams that don't sit at desks, this matters.
Task management is a nice extra. Assign tasks to shifts or employees. Opening checklists, closing procedures, prep lists. Most scheduling tools don't touch this.
Multi-location support on all plans. Even the free plan lets you manage multiple locations. Deputy charges $30/month minimum. Homebase charges per location. Sling doesn't.
One manager on Reddit put it simply: "We use Sling for multiple locations and like it. It's $70/month which is reasonable compared to many other options."
Where Sling falls short
No time tracking on the free plan. This is the biggest gap. You can schedule shifts but can't track if people actually showed up on time. Most teams discover they need time tracking within 2-3 months, which means upgrading to Premium.
Mobile app sync issues. This comes up in almost every review thread. Shifts sometimes show differently on phone vs desktop. Schedule changes don't always push to the app immediately. As one Capterra reviewer noted: "The app can feel slow or glitchy at times." For a tool where most of your team uses the mobile app, that's a real problem.
The 30-user cap. Great for a single small location. But open a second location or grow past 30 employees and you're forced onto a paid plan. The jump from $0 to $1.70/user feels bigger than it should because you've been getting it for free.
Limited reporting. Basic reports exist on Premium, but anything useful for labor cost management requires Business ($3.40/user/month). If you need to know "am I spending too much on overtime?" you're paying for the top tier.
2024 shift swap change. Sling restricted shift swap visibility to managers only. Some admins lost the ability to see time-off requests entirely. This was a significant workflow change that frustrated long-time users.
Pricing breakdown
| Free | Premium | Business | |
|---|---|---|---|
| Monthly | $0 | $2/user | $4/user |
| Annual | $0 | $1.70/user | $3.40/user |
| User cap | 30 | Unlimited | Unlimited |
| Scheduling | Yes | Yes | Yes |
| Time tracking | No | Yes | Yes |
| Overtime alerts | No | Yes | Yes |
| Labor cost reports | No | No | Yes |
| Kiosk clock-in | No | Yes | Yes |
| Integrations | Limited | Limited | Full |
The hidden cost: You might start on Free, but you'll likely need Premium within months. And if you have more than one location and care about labor costs, you'll end up on Business. A 25-person team on Business pays $1,020/year.
Who should use Sling
Good fit:
- Small teams under 30 who only need scheduling (no time tracking)
- Budget-conscious businesses that want to try scheduling software before paying
- Teams that value built-in messaging (reduces WhatsApp chaos)
- Restaurants and retail shops at a single location
Not a good fit:
- Teams that need time tracking from day one (you'll pay anyway)
- Businesses over 30 employees (free plan doesn't apply)
- Teams that need GPS clock-in or geofencing (Sling doesn't offer this)
- Managers who need labor cost reports without paying for the top tier
How Sling compares to Turnozo
| Sling (Premium) | Turnozo | |
|---|---|---|
| Price | $1.70/user/mo (annual) | $2.47/user/mo |
| Time tracking | Yes | Yes |
| GPS clock-in | No | Yes |
| Geofencing | No | Yes |
| Shift swaps | Yes | Yes |
| Team messaging | Built in | No (use WhatsApp/Slack) |
| Task management | Built in | No |
| All features included | No (needs Business for full) | Yes |
Sling is cheaper per user on Premium. Turnozo is more expensive but includes everything, including GPS verification and geofencing that Sling doesn't offer at any price. If you need time tracking with location verification, Turnozo wins. If built-in messaging matters more, Sling has the edge.
The bottom line
Sling's free plan is one of the best in the market. If you have under 30 employees and genuinely only need scheduling (no time tracking, no reports), it's hard to beat free.
But most teams outgrow it. And when you do, the pricing math changes. Sling Premium at $1.70/user is competitive but doesn't include labor cost reports. Sling Business at $3.40/user does, but at that point you're paying more than most alternatives.
The real question isn't "is Sling good?" (it is). It's "will Sling still be the right choice in 6 months when your needs grow?" If you're already thinking about what comes after Sling, see our full comparison of Turnozo vs Deputy vs Sling.

Frequently asked questions
Yes. Sling's free plan covers up to 30 users and includes shift scheduling, time-off requests, team messaging, and a newsfeed. However, it doesn't include time tracking, overtime monitoring, labor cost reports, or the time clock kiosk. Those require the Premium ($1.70/user/month annual) or Business ($3.40/user/month annual) plan.
Premium adds time tracking, overtime alerts, PTO management, and the kiosk clock-in feature. Business adds labor cost management, advanced reporting, integrations with payroll systems, and custom user permissions. For most small teams, Premium covers what you need.
Yes. Multi-location scheduling is available on all plans, including the free tier. However, managing labor costs across locations requires the Business plan.
Sling's free plan is more generous (30 users vs Turnozo's 30-day trial). But once you need time tracking, Sling Premium costs $1.70/user/month while Turnozo costs $2.47/user/month with all features included, no tier upgrades needed. Turnozo also includes GPS clock-in and geofencing, which Sling doesn't offer.
The most common complaints are mobile app sync delays (shifts showing differently on phone vs desktop), the 30-user cap on the free plan, limited reporting on lower tiers, and a 2024 change that restricted shift swap visibility to managers only.
