## What is Timeshifter Shift Work?

Combat shift work disruption with personalized advice based on the latest circadian science.

This groundbreaking app empowers shift workers to optimize their sleep, performance, health, and quality of life with science-based guidance developed by world-renowned circadian scientists.

Fast Company: “Congratulations Timeshifter on helping to change the world.”

Timeshifter — Shift Work Edition — was developed to help shift workers reduce the underlying problem of circadian and sleep disruption inherent in shift work. With Timeshifter, you will receive highly personalized advice based on your sleep pattern, chronotype, work schedule, and personal preferences.

SHIFT WORK MYTHS VS. CIRCADIAN SCIENCE

Shift workers face a serious biological challenge: misalignment between their internal circadian rhythms and their work schedules. This circadian disruption leads to insomnia, excessive sleepiness, poor performance, and increased long-term health risks.

Popular advice — like drinking more coffee, using supplements, or simply “getting more rest” — misses the mark. These approaches don’t address the root cause: your circadian misalignment.

It’s time to replace the myths with real science.

Generic tips won’t solve circadian disruption. Only evidence-based interventions that "reset" your circadian rhythms and manage circadian timing can effectively reduce the negative effects of shift work.

THE REAL SCIENCE OF SHIFT WORK

// In your brain, a circadian clock regulates the rhythm of your day.
// Shift work causes your sleep and other behaviors to occur at biologically inappropriate times, resulting in fatigue, poor sleep, and long-term health risks.
// Light is the most powerful cue for resetting your circadian clock. The correct timing of light exposure and light avoidance is the foundation of any circadian intervention to improve alertness and sleep quality. If your timing is off, it can make things worse.

WHY SHIFT WORKERS LOVE TIMESHIFTER

// Based on the latest sleep and circadian science
// Optimizes your sleep, alertness, and performance
// Reduces the negative effects of shift work on productivity, health, and quality of life

Using Timeshifter is as simple as taking small actions at specific times.

KEY FEATURES

// Circadian Time™: Advice is based on your individual circadian clock
// Practicality Filter™: Adjusts advice to work in the "real world"
// Quick Shift Entry: Add work schedules across multiple dates in seconds
// Commute Time: Include commute and “get ready” times to ensure practical advice
// Fatigue Prediction: Warns you when to be extra cautious to avoid mistakes and accidents
// Advice Notifications: Get timely advice even without opening the app

### 3/5 — Almost good

*2026-07-29*

I’ve been using this for a couple months and when it works it’s super helpful but I wish it had more integrations like able to import your schedule and have different calendar views. Night mode would also be amazing. Lastly this after latest update it keeps logging me out while I’m adding shifts and doesn’t save the progress :/

### 2/5 — Bugs!

*2026-07-14*

I love this app for regulating my sleep for my overnight shifts and it’s so helpful in keeping me from feeling tired, but since having it there’s been 2 bugs that completely keep me from getting into the app. :(

**Developer response:** Hi Jessica, That doesn't sound right. Would you mind reaching out using the in-app chat, so we can get this sorted out? As far as I know we should have fixed all the know bugs at this point, so I am surprised to hear that you're experiencing issues. Please help us get some clarity here, so we can make sure this does not happen again – not for you or any other users of the app. Thank you.

### 4/5 — Great for shift workers!!

*2026-04-16*

Been using for over a year. My work schedule includes multiple shift changes per week and prior to using this app I was never getting the sleep I needed. For many years I was constantly drinking caffeine to stay awake, melatonin to fall asleep. I was never able to maintain a schedule outside of work because I never knew when I was going to be too tired. This app makes it super easy to make changing sleep schedules manageable. I only give it 4 stars because it does not include a good time to exercise.

### 3/5 — Nicht flexibel

*2026-04-05*

Ich wollte meinen komplett kaputten schlafrythmus am Anfang eingeben, und schon das merke ich - für mich interessiert der Macher dieser App sich nicht. Denn die einschlafzeit kann nur zwischen 22-3 Uhr morgens oder so eingegeben werden. Was soll der Unsinn?

### 5/5 — IT support

*2025-06-09*

Friend recommend this app to me. I work on IT production support for different countries and time zones. I loaded all my different shifts and followed recs it helped my sleep quality tremendously. 100 % worth trying.

**Developer response:** Thank you so much for sharing 🙏🏻

### 5/5 — Review

*2025-05-29*

Nice app to handle the constant changes to shift timings

### 5/5 — Necessary for human function

*2025-05-29*

After you start using this, you won’t go without it. It’s like trying to wake up with an alarm clock, go somewhere without a gps or directions, cook without a recipe. It honestly relieves a lot of stress as you are able to defer / trust something like this and not “have to think about it”. Like anything in life I don’t follow it if I don’t want to, but it’s always helpful to know the guidelines and how far off I am. If this synced up to Apple Watch Fitbit etc and gave me a score for how well I was doing that would be awesome and gamify it

### 5/5 — Works great!

*2025-05-19*

I had a 4 day workshop but it was from midnight-8:00 am and my regular schedule of sleep is from 8:00 pm -5:00 am. I used the app to make this Shift and it was perfect. I was able to be awake and alert and still get in 8 hours of sleep. I followed the recommendations for when to get light, drink caffeine and sleep. Thanks Timeshifter Work for making that possible.

### 5/5 — Amazing!

*2025-05-16, version 1.0.5*

I have been using this app during the beta, it has helped me get much better sleep and realized how important we rely on sunlight. I can see this app being great for nurses, doctors,customer service reps,IT workers, security guards, security analysts. Basically anyone with odd hours during shift with can benefit from this app.

### 5/5 — Simply works

*2025-05-04*

Long time user of Timeshifter and this is hands down the best for shift work. So simple and I felt the changes right away.
