Get this choice wrong and your managers end up running two systems side by side: the app for rotas and a spreadsheet for everything it can't reach. Deputy vs When I Work comes down to scope, because Deputy describes scheduling, HR, AI labour forecasting and payroll in one product, while When I Work describes shifts, a time clock and team messaging in one mobile-first app.
Shift-based teams live inside their scheduling software. A rota that goes out late, a swap agreed in a group chat that nobody wrote down, a timesheet that doesn't match who turned up: those are the headaches restaurant, retail, care and service managers want gone when they compare these two. Below is what each vendor says on its own site, where the two part ways, and a way to decide for your team. I'm not scoring them. Which one fits depends on how much of your back office you want one app to carry.
How each one describes itself
Deputy's homepage calls it easy-to-use employee scheduling, HR, AI labour forecasting and payroll software. That's the wording to hold on to, because it tells you the product is pitched at far more than the rota. The site talks about tracking wage spend live so managers can make decisions every day, and it says it works out pay rates, overtime and premium pay automatically, with no manual sums. On the staff side, it says your team can manage schedules, swap shifts and clock in without training. It also says it uses AI models to tune schedules and staffing at every location, which points it at businesses with more than one site.
When I Work's homepage is narrower and plainer: schedule shifts, track time and message your team in one app. Its time clock turns any device into a tracker for attendance, breaks and time off. Messaging lets everyone on the team talk in one place without handing out phone numbers. Rather than building payroll in, it talks about connecting with the tools you already rely on for scheduling, payroll and more. It describes itself as one mobile-first platform for managers and employees, and it speaks straight to teams still running shifts from spreadsheets or group texts, calling itself the upgrade from those.
So one vendor is selling a wider workforce system, and the other is selling a cleaner way to run the rota and the time clock, with your existing payroll sitting alongside it.
Upsides and downsides of each approach
This isn't about which product is better built. It's about what a wide suite and a focused app each tend to do well, and where each tends to ask more of you.
A suite that reaches into payroll
The upside of the Deputy approach is fewer hand-offs. If the same system that builds the rota also calculates overtime and premium pay, there's less re-keying between the schedule and the pay run, and live wage tracking puts the spend in front of a manager while the week's still going. Forecasting with AI models is aimed at the question every multi-site manager asks on a Sunday night: how many people do we need on, and where?
The downside is that more of your business ends up depending on one setup. Payroll rules, HR records and forecasting all need configuring, and somebody has to own that. A small single-site cafe may find it's switching on far more than it needs.
A lighter app built around the phone
The upside of the When I Work approach is focus. Shifts, clocking in and team messaging are the three things most frontline staff touch, and a mobile-first app that keeps those in one place is easy to roll out to people who'll never sit at a desk. Messaging without sharing phone numbers matters more than it sounds for teams with students, part-timers and high turnover.
The downside is that payroll lives somewhere else. Its page talks about integrations that connect scheduling to payroll, so the link between hours worked and money reaching someone's account runs through another tool, and that connection needs testing before you commit.
Both start with a trial, not a free plan
Here's the detail people miss when they search for a free scheduling app. Neither of these homepages offers a permanent free plan. Deputy says start for free with no credit card required, and that start is a trial window. When I Work's call to action is start your free trial. So whichever you lean towards, you're on a clock from the day you sign up.
That changes how you should run the test. Don't sign up for both on a quiet Tuesday and poke around. Get your real rota, your real staff list and one real pay period ready first, then start the trial, so the time goes on the work that'll tell you something. And remember the bigger difference still isn't the trial at all. It's scope: one is pitching scheduling plus HR, forecasting and payroll, the other shifts, time and messaging.

Run one real week through both
A trial only tells you something if you feed it a real week. Here's a simple way to do that without upsetting the team.
- Load next week's rota into both, with real names, roles and the staff who can't work certain shifts.
- Ask two staff members to swap a shift in each app from their own phones, and note how long it takes.
- Clock in and out on a shared device and on a personal phone, including a break.
- Send a team message about a change and check who saw it.
- Take the hours from that week through to your payroll step, inside the app or through the connection it offers, and compare it with what you'd have done by hand.
- Ask the manager who'll live with it which app they'd open on a busy Saturday.
That last question carries more weight than any feature list. The app your shift leads open without being chased is the one that gets used.
Matching the app to your rota
If you run several sites and you're tired of reconciling rotas with pay by hand, Deputy's mix of scheduling, live wage tracking, pay calculations and forecasting is pitched straight at you, so start your trial there. If you run one or two sites, your payroll already works and the real pain is shift swaps, clocking in and chasing people on group texts, When I Work's focused, mobile-first app speaks to that, so put it first. Either way, my advice is the same: don't decide from the homepage. Decide from one real week.

Frequently asked questions
Does Deputy offer a free plan?
Not a permanent one on its homepage. It invites you to start for free with no credit card required, and that's a trial. Plans and limits change, so check the vendor's own site before you sign up.
Does When I Work offer a free plan?
Its homepage leads with a free trial rather than a free plan. Check the vendor's own site for current options, because what's offered can change.
Which of the two handles payroll?
Deputy describes payroll as part of the product and says it calculates pay rates, overtime and premium pay automatically. When I Work talks about integrations that connect scheduling with payroll and the other tools you already use.
Can staff swap shifts and clock in from their phones?
Deputy says your team can manage schedules, swap shifts and clock in without training. When I Work calls itself mobile-first and says its time clock turns any device into an attendance, breaks and time-off tracker.
Can I message my team without sharing phone numbers?
When I Work says so directly: everyone on the team can communicate in one place without sharing phone numbers. If team messaging matters to you, test it in both trials.
Does either app forecast staffing?
Deputy describes AI labour forecasting and says it uses AI models to set schedules and staffing at every location. When I Work's homepage centres on shifts, time tracking and messaging instead.
