Terms of use | TurnoRest

The agreement

By using TurnoRest you agree to these terms. If you do not agree, delete the app; there is no account to close. The Privacy Policy says what else there is to delete, and how.

TurnoRest is also covered by Apple’s Standard End User License Agreement, available at apple.com/legal/internet-services/itunes/dev/stdeula. Where these terms and Apple’s EULA differ, Apple’s EULA governs the license to use the app itself.

What TurnoRest is

TurnoRest is a calculator for shift work. You give it your shift pattern; it derives your schedule, works out where sleep fits in the gaps between your shifts, and flags when your schedule drifts from published rest thresholds.

What TurnoRest is not

TurnoRest is not a medical device. It does not diagnose, treat, or prevent anything, and it gives no medical advice. Its sleep windows are a plan built from your schedule and from published sleep guidance, and each tip names its source. The app does not measure your sleep itself: if you allow it, it only reads sleep already recorded in the Health app, to confirm windows. Shift work sleep disorder is a medical condition, and it can be treated. If you are struggling with sleep or tiredness, talk to a doctor.

TurnoRest does not give legal advice. The app cites published rest thresholds and says where each one comes from, including whether it is law or convention in your country. In the United States there is no federal limit on working hours and no mandatory minimum rest period for most workers, and the app says so. Nothing in TurnoRest creates or enforces rights against an employer, and it doesn’t interpret the ones you have. For that, talk to a lawyer or your union.

Where the numbers come from

Every warning and every sleep tip in the app cites its source, and every source opens with a tap. The full list is on screen under Settings › Recovery criteria › Where these numbers come from. The laws, guidance and studies cited were checked against their pages on September 17, 2026.

Rest between shifts, 11 h: law in the European Union (Directive 2003/88/EC, art. 3) and the UK (Working Time Regulations 1998, reg. 10). In the United States it is guidance: NIOSH’s training for nurses cites Knauth & Hornberger’s recommendation of at least 11 hours between shifts.
Weekly rest: in the European Union, 24 hours of uninterrupted rest plus the 11 hours of daily rest every 7 days, with 24 hours alone only as an exception (Directive 2003/88/EC, art. 5); in the UK, the Working Time Regulations 1998, reg. 11. The app flags 7 days in a row without 24 hours off. Outside the EU and the UK that 24-hour check is the app’s convention; in the United States the app shows it next to NIOSH’s related advice of 1–2 full days off after 5 × 8 h or 4 × 10 h shifts, and 2 days after 3 × 12 h shifts.
Hours in 7 days: in the European Union and the UK, an average of 48 hours: law, averaged over a reference period, so one heavy week is a signal, not a breach. In the United States the app warns above 40 hours, because NIOSH’s training for nurses reports that more than 40 hours of work a week is associated with worse patient care and risks to the nurse’s health. Elsewhere, 48 hours is used as a convention. Above 60 hours is critical everywhere: that is the limit the Institute of Medicine recommended for nurses, cited by NIOSH, and working at least 60 hours a week was linked to a higher injury rate (Dembe et al. 2005).
Consecutive nights, 3: expert recommendations (Garde et al. 2020) and the UK Health and Safety Executive (2–3). NIOSH itself says to keep consecutive night shifts to a minimum without giving a number.
Shift length, 12 h: the Institute of Medicine’s limit of 12 hours in any 24, cited by NIOSH, and the UK Health and Safety Executive. For night shifts, several of these sources suggest shorter shifts, and the app shows that too.
The app’s own conventions: rest under 8 h, a 5th night in a row, a shift over 14 h, and the 4-hour recovery sleep after the last night come from no published document. They are the app’s choices, and the app labels them as convention.
Sleep tips: going to bed soon after a night shift, the nap before a night shift, the first and last night of a block, and the defaults (7.5 h of main sleep, a 90-minute nap) come from NIOSH’s training for nurses, the American Academy of Sleep Medicine, a BMJ practice review, and published studies. The evidence is modest (mostly guidelines, expert opinion, and small studies), and the app says so.

The app does not grade you. It shows five measures taken from your own schedule (the shortest rest, days in a row before a day off, nights in a row, longest shift, and hours in seven days), each in its own unit, next to the reference and the source it cites. They are not added into a single number: hours of rest and nights in a row share neither a unit nor a source, and any weighting that combined them would be invented by us.

None of these measures is a physiological measurement. They are counts taken from your schedule, not readings of your body.

Until September 5, 2026, there was a 0–100 number here called a “recovery score”. It is gone because it measured nothing: it was 100 for anyone on a named rotating pattern, and 0 for anyone whose schedule is made only of changes.

TurnoRest is not a payroll system. The pay calculation multiplies your hours by figures you enter yourself. It excludes taxes, deductions, allowances, and everything else your actual paycheck contains. It’s a way to check your pay; it isn’t evidence of what you’re owed.

The numbers depend on what you put in. If your pattern, anchor date, or hourly rate is wrong, everything downstream is wrong. The app shows its working so you can check it.

Free access, subscriptions and the lifetime purchase

TurnoRest is free for what you do every day: the schedule, the sleep windows, the warnings, the widget, the reminders, this week’s pay total and, from version 1.1, whether each period’s pay stub matches the app’s figure, with no time limit. TurnoRest Pro adds the pay breakdown, each pay period’s total and line items, what a swap or an extra shift changes, the statistics, the year, the schedule of the person you live with, other jobs, the calendar sync and, from version 1.1, which line item matches a pay stub difference and the history of checked pay stubs. Before version 1.1, checking a pay stub is part of Pro. Prices are shown in the app in your local currency before you buy anything.

TurnoRest Pro is sold as three options, and not all of them are subscriptions:

Yearly and monthly are auto-renewing subscriptions. They renew automatically until canceled. Cancel any time, at least 24 hours before the renewal date: in iPhone Settings › your name › Subscriptions, or in the app under Settings › Subscription.
The yearly plan may start with a free trial: 14 days when these terms were last updated. Before you start it, the purchase screen shows how long it lasts and the price you will be charged when it ends. Apple offers it once per Apple Account: if you have subscribed to TurnoRest Pro before, yearly or monthly, the trial is not offered again. When the trial ends, the yearly subscription starts and you are charged, unless you cancel at least 24 hours before the trial ends, in the same places as above. Cancelling during the trial costs nothing, and access may end as soon as you cancel. The monthly plan and the lifetime purchase have no trial.
Lifetime is a one-time, non-consumable purchase. It is charged once. It never renews or expires, so there is nothing to cancel. If you change phones or reinstall, tap Restore purchases while signed in with the same Apple Account and it comes back.
Refunds are handled by Apple, not by us. Request one at reportaproblem.apple.com.

Your schedule, your changes, and your history remain on your device whether you subscribe or not.

Liability

TurnoRest is provided “as is”, without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement.

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages, or for any loss of profits or data, arising from your use of the app. Our total liability is limited to the amount you paid for TurnoRest in the twelve months before the claim.

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of liability for incidental or consequential damages. In those places, the exclusions above apply only to the extent permitted, and you may have additional rights.

Nothing here limits your statutory consumer rights, including those under the laws of your state or country.

Changes to these terms

If these terms change, the date at the top changes with them. Continuing to use the app after a change means you accept it.

October 1, 2026: The free and Pro lists say which pay stub features start with version 1.1. Before it, checking a pay stub is part of Pro.
September 27, 2026: With version 1.1, whether each period’s pay stub matches is free, and Pro adds which line item matches a difference and the history of checked pay stubs. The yearly plan may start with a free trial, and these terms say how long it lasts, what it costs after and how to cancel it.
September 25, 2026: Wording edited in a few places, with no change in meaning.
September 24, 2026: Plainer wording and US spelling (“schedule” for “rota”, “canceled”), with no change in meaning.
September 19, 2026: The full list of what Pro adds, canceling from the app’s own Settings › Subscription, and a pointer to what the Privacy Policy says to delete.
September 18, 2026: Pro is sold as three options, and the lifetime purchase renews nothing and comes back with Restore purchases.
September 17, 2026: Where each number in the app comes from, source by source, and what the sleep windows are and are not.
September 5, 2026: The app is renamed TurnoRest. The 30-day trial ends: the everyday app is free with no time limit, and Pro adds the rest. The terms say where each warning’s numbers come from.
August 31, 2026: First version published at turnorest.com.

Governing law

These terms are governed by the laws of Portugal, where the developer is established, without regard to conflict of law principles. This does not deprive you of the protection of the mandatory consumer laws of the place where you live.
