Knock off
on time.

No, and it doesn't pretend to. Companies and agreements all differ, so you enter your own base rate and your overtime, weekend, night and holiday rates. When more than one rate applies to the same minute, the highest one is used, not all of them stacked on top of each other. Always check it against your payslip, and if something looks wrong, ask your employer or the Fair Work Ombudsman.

You save a usual travel time for each site once, by checking it in Google Maps or Apple Maps. Tools Down adds the buffer you choose and works back from your start time. It doesn't track where you are or check live traffic.

Yes, through your phone's calendar. A web app can't send alerts by itself without a server, so your shifts go into your calendar with an alert the night before and another when it's time to leave, and your calendar does the reminding.

Tap Sent home early and the pay is worked out to that minute, with your minimum hours if you get them. Called off late and still paid? Mark the shift cancelled and say how many hours were paid. Sent to another job instead? That's not a cancellation: keep it as worked at the new site, from the original start time.

Leave the finish time out. On shift, Today counts up the time on the clock and what you've earned, and Knock off now puts the finish time in when you're done. Forget, and it asks you later. Until then, the shift only counts what's certain, like your minimum hours.

It shows roughly what you'll take home, worked out the way your employer's tax tables do it, from the ATO's rates for Australian residents. Tell it whether you claim the tax-free threshold and whether you're paying off HELP or another study loan. It's a rough guide only: your payslip might be a few dollars different, and your real tax is worked out at tax time.

No. It's a rough guide from the ATO's general rates, and it doesn't know your whole situation, like other income, a second job, deductions or offsets, so don't rely on it for decisions about your tax. For advice about your own tax, talk to a registered tax agent or accountant.

Yes. It's concrete grey by day and dark bitumen at night. Leave it on Automatic and it goes dark from 7pm to 6am, or have it follow your phone, or pick light or dark.

Your shifts live on your phone only, so losing it or clearing the browser loses them too, unless you've got a backup. Tools Down reminds you once a month. A backup is a single file, photos included, that you can email to yourself or keep in Drive or iCloud, and it restores on a new phone.

Yes. A step-by-step user guide is built into the app, under More: getting started, setting up your pay, sites, shifts, pasting a shift message, calendar reminders, pay, backups and more. Each step of setup has a tip that opens the right part of it.

No. It started with a traffic controller in Sydney and it's built for site crews: traffic control, labourers, trades and labour hire, at sites that keep changing. But anyone paid by the hour can use it. The countdown to knock-off and the dollars adding up work just as well in a warehouse, a kitchen or a shop, and knowing what's coming in helps with the budget. On the same hours every week? Set a shift to repeat and it keeps going until you stop it.

Not yet. For now the state is set to NSW and it knows NSW public holidays.

It isn't open yet. It's being tested on real shifts first. The plan is every feature free for 14 days from your first shift, then A$6.99 a month or A$59 a year. Register your interest and you'll get one email when it opens.
