F.lux este un nou tweak disponibil pentru posesorii de iDevice-uri care permite utilizatorilor sa schimbe culoarea propriului ecran in functie de perioada din zi in care utilizeaza terminalul. Ideea din spatele acestui tweak a venit din cauza felului in care isi schimba terminalele noastre luminozitatea ecranului si tonalitatea culorilor, dezvoltatorii F.lux promitand ca prin utilizare acestui tweak ne vom proteja ochii impotriva culorilor prea puternice. Practic F.lux ne permite sa schimbam tonalitatea culorilor pentru zi/noapte astfel ca putem seta culori calde/reci in diverse tonuri pentru dispozitivul nostru in functie de mediul in care il folosim.
Select the type of lighting in the room you’re in at night, and then forget about it. Each evening at sunset, f.lux warms up the colors on your phone. At dawn, f.lux returns your phone to daylight colors. We made f.lux because one day we noticed that all our laptops were the wrong color temperatureat night. They looked fine during the day, but at night, they were much too blue. We realized that looking at the sun all night long might not be such a good idea. After researching blue light’s effects on health, we found lots of evidence that color matters even more than brightness. And it turns out that timing matters, too: <strong>Blue light during the day is great for your circadian rhythm. Blue light at night is not.
Sleep researchers have just begun studying the effects of night-time usage of laptops, cell phones, iPads and other devices that emit blue light. Evidence suggests that even just a little extra blue light at night can keep you awake later and negatively affect the quality of your sleep. Our users say that f.lux prevents eyestrain. They also say that it’s easier to wind down and go to sleep after using a f.lux-enabled device at night. Plus, you’ll never glow blue in a restaurant again. You can use f.lux because it makes you sleep better, or you could use it because it just makes you look better. Either way your eyes will thank you.
Din aplicatia Settings a iOS putem seta tonalitatea culorilor ecranului in timpul noptii astfel ca atunci cand lumina ambientala detecteaza un mediu cu luminozitate scazuta va activa automat si tonalitatea culorii aleasa pentru ecranul nostru. Putem seta pentru tweak si rapiditatea tranzitiei dintre culoarea ecranului astfel ca pentru dispozitive vechi este necesar sa setam o perioada de tranzitie mai lunga iar pentru cele noi o perioada mai scurta. F.lux este disponibil gratuit in Cydia in repo-ul BigBoss si este compatibil cu toate iDevice-urile.
After installation: open Settings and tap f.lux. Choose your lighting type and transition speed (for older devices the long transition is instant to avoid flickering). By tapping each lighting option you can see a short preview of how your screen will look like after sunset. If your screen appears orange, open settings and select a different lighting type. f.lux should make your phone look just like a book under your room lighting. f.lux should have a minor impact on your battery life. f.lux itself uses less than 2 seconds of CPU each day, but Location Services can be a larger drain. We are currently working to optimize battery usage. f.lux uses a low power mode to determine your location. We don’t record or track where you are – there’s no server on our end.
The current version of f.lux requires Location Services to be enabled. If you install it with Location Services off, a reboot or reinstall is required to make f.lux work. iPhone 3g support is experimental and may slightly shift your colors during daytime. If you don’t like the shift, uninstall f.lux and reboot your phone to restore to normal colors. You can turn f.lux off at any time by choosing “Off” under the Enabled option in f.lux settings.
