Set monitor brightness/ colours to match the time of day

Iris is a simple application which automatically varies your display brightness and colour temperature according to the time of day, with the aim of reducing eye strain.

The program does this entirely automatically. Just launch Iris and it detects your location, adjusts display settings and updates them over time.

If this causes any problems, a system tray menu has right-click options to pause the effect or close the program entirely. (Iris doesn't install any drivers, services or other low-level components, so closing it down will return your system to normal immediately.)

Is Iris any better than the host of similar tools? The developer says:

Some of the benefits of Iris over competitors are that Iris works even on docking stations and monitors connected with USB with the help of my custom High level Color-API, it has really bigger blue light reduction color range compared to all other alternatives, brightness without pulse-width modulation, manual settings, color effects, font rendering, magnification and part screen blue light reduction with the help of full screen overlays.

The Free version gives you only the most basic functionality, but if you're interested in this topic, spending $10 on a lifetime licence to the Pro build does deliver a lot more:

 - Iris high and low-level Color APIs
 - Preserves perfect display calibration during the day
 - Temperature slider
 - Brightness slider
 - Manual/Automatic Temperature
 - Manual/Automatic Brightness
 - Manual/Automatic Location
 - Manual Night duration
 - Keyboard shortcuts
 - Multiple monitors option support
 - Pause color changes when this software is running
 - Everything in Iris lite
 - Multiple Color temperature schemes - Magmus, Olaf, Iris
 - Color inversion and color effects
 - GDIPP, ClearType and other font renderings
 - Break reminding and timers
 - Part screen color changing
 - Block webistes and applications
 - Magnification
 - AI
 - Blink detection
 - Exercises
 - Automatic updates
 - Hidden features
 - New features and innovations


The free version of Iris is very short on features when compared to the competition. The developer says it's technically better, but is that really true? We don't know.

The paid build seems much more powerful, but there's no trial available, so again it's difficult to give a verdict.

If you're interested in this approach to eye health then we'd say try Iris anyway, see if you notice a difference, but otherwise there's no obvious reason to select it above anything else.

WhatsApp Messenger 2.18.51

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

What's New in Version 2.18.51

• When you receive a link to an Instagram or Facebook video, you can now play it right within WhatsApp. With picture-in-picture, you can also keep watching the video while you navigate to another chat.
• If you're a group admin, you can now remove admin rights from other participants. Select the admin in "Group Info" and tap "Dismiss As Admin."
• Group admins can now choose who can change a group's subject, icon and description by going to "Group Info" and tapping "Group Settings."
