Tools

Non-24 Calculator
This calculator is helpful for Non-24 patients with a predictable shift.
Many patients do not have a predictable shift (meaning, the amount of forward shift may change from day to day).

Sleep As Android
Sleep tracking for android devices. Costs around $5 including cloud backup; has free options.

Sleep as Android Graph of a Non-24 Sleep Pattern

Pros: Has a free trial and can be used by watching an ad. Many features including gentle alarms, syncs with smart bulbs through IFTTT, lullabies, sound recording, Spotify and Play Music integration, and more. Integrates with several watches which track heart rate, such as Mi Band, Galaxy Gear, Garmin, etc.

Cons: Free trial is limited and ads are annoying unless you purchase the app. Limited exporting for graphs useful to Non-24 patients. Screenshots only (see image).

Their website is https://sleep.urbandroid.org/ (the title links to their Google Play store page).

Sleepmeter Free
Sleep tracking for android devices.

A small app which lets you manually record the times you sleep/wake and provides many graphs which can show useful information. I use it to get an idea of what my sleep deficit is and to try to predict my sleep patterns for the next few days.

Sleepmeter Free Graph of a Non-24 Sleep Pattern

Pros: Free (ad supported but they are unobtrusive, and there is a pay-to-remove option). Easy to use once set up. Has a widget for your home screen so you can tap when you go to bed, and tap when you wake up (time between the “bedtime” tap and “asleep” is configurable, as is the wake-up tap). Very customizable and configurable. Lots of useful graphs and information. Does not rely on device sensors. Can export/import data in CSV format (it’s not quite a standard CSV but it’s close).

Cons: Configuration options might be a bit daunting to some. Requires manual taps to tell it you’ve gone to bed/woken (though I prefer this over sensor based detection as I find it more reliable and it also means I don’t need to leave my phone on charge all night on my bed). Doesn’t seem to be actively updated, but to be fair it does work fine as it is.
