Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night.

Are you having trouble falling asleep? Are your kids hyperactive when playing with the tablet before bed time?
Are you using your smart phone or tablet in the late evening? Twilight may be a solution for you!

Recent research suggests that exposure to blue light before sleep may distort your natural (circadian) rhythm and cause inability to fall asleep.

The cause is the photoreceptor in your eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range which may suppress Melatonin production - a hormone responsible for your healthy sleep-wake cycles.

In experimental scientific studies it has been shown an average person reading on a tablet or smart phone for a couple of hours before bed time may find their sleep delayed by about an hour. See references below..

The Twilight app makes your device screen adapt to the time of the day. It filters the flux of blue light emitted by your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter. The filter intensity is smoothly adjusted to the sun cycle based on your local sunset and sunrise times.

You can also use Twilight on your Wear OS device.

1) Bed reading: Twilight is more pleasant on the eyes for night reading. Especially as it is able to lower the screen backlight far below the ability of the backligt controls on your screen

2) AMOLED screens: We have tested Twilight on an AMOLED screen for 5 years without any sign of depletion or over-burning. If properly configured Twilight causes less light emission (by enabling dimming) with more equal light distribution (dark areas of the screen such as the status bar get tinted). This may in fact increase your AMOLED screen life time.

- write settings - to set back-light
- network - access smartlight (Philips HUE) to shield you household light from blue

Accessibility Service

In order to filter also your notifications and lock screen the app may ask for enabling Twilight Accessibility Service. The app uses this service only to better filter your screen and does not collect any personal information.

One-Tap Sensor Logger in Your Pocket with Watch, Streaming, Bluetooth, Rule Engine & Crowd-Source StudySensor Logger collects, records and displays data from a range of sensors on iPhone, Apple Watch, iPad and AirPods â including accelerometer, gyroscope, GPS, audio, camera and Bluetooth devices. You can log device properties such as screen brightness, battery and network state. Select and preview desired sensors in a few taps. A single tap initiates the recording function, which works even when the app is in the background. View and manage recordings within the app via interactive plots. The app supports many export formats, including Zipped CSV, JSON, Excel, KML and SQLite. For advanced use cases, you can stream data via HTTP, resample measurements from multiple sensors, create Studies to collect data from other users systematically and write custom automation rules based on sensor, time and location.Sensor Logger is designed for researchers, educators, and anyone interested in collecting or monitoring sensors on their smartphone. It serves as the ultimate toolbox for exploring various fields, including physics, science, technology, engineering, and mathematics (STEM).Main Features- One-tap logging- Background recording- Recordings on interactive plots- Stream data via HTTP- Intelligent, custom rule engine- Zipped CSV, JSON, Excel, KML & SQLite exports- Resample and aggregate measurements- Enable & disable specific sensors- Scan and log nearby Bluetooth devices- Add timestamp-synchronised annotations during recording- Adjust sampling frequency for sensor groups- Custom recording workflow- Raw and calibrated measurements available- Live plots and readings for sensors- Organise, sort and filter recordings- Control & track recording session from Watch- Bulk export & delete recordings- Resources to help you analyse your data- Data stays on-device and privateStudies & Sensor Logger Cloud- Create Studies to collect data from other Sensor Logger users.- When a Study is activated, the exact sensor configuration, as prescribed by the investigator, is used to ensure data collection consistency.- Study participants can seamlessly upload their recordings to a secure cloud.- Create custom questionnaires, filled out by the participants.- Create Studies with clear data usage descriptions, privacy statements and contacts to ensure compliance.- Keep track of participant count, recording number, and other statistics.Optional Paid Features (Plus, Pro & Ultimate)- No limitations on the number of stored recordings- Additional export formats- Combined CSV export- Customise recording workflow- Advanced sensor configurations- Custom naming templates- Theme and icon customisations- Unlimited number of simultaneously toggled Bluetooth sensors and no limit on the minimum RSSI- Create larger Studies with more participants- More allocated storage for Studies using Sensor Logger Cloud- Email support- Advanced study customisation, including creating custom accompanying questionnaires and custom Study IDSupported Measurements- Device Acceleration (Accelerometer; Raw & Calibrated)- Gravity Vector (Accelerometer)- Device Rotation Rate (Gyroscope)- Device Orientation (Gyroscope; Raw & Calibrated)- Magnetic Heading (Magnetometer; Raw & Calibrated)- Barometric Altitude (Barometer)- GPS Coordinate, Altitude, Speed & Heading- Audio (Microphone)- Loudness (Microphone)- Camera Images (Front & Back)- Camera Video (Front & Back)- Pedometer- Heart Rate (Requires watch)- Wrist Motion (Requires watch)- Annotations (Timestamp and text)- Device battery level and state- Device screen brightness level- Nearby Bluetooth beacons (advertised data)- Headphone Motion (AirPods)- NetworkNote that heart rate logging requires integration with the Health app on the watch.
