Light Flow is the kind of app that best showcases Android's sensibilities: esoteric, amazingly customizable, and downright impossible on other platforms. The popular notification manager for devices with LED indicator lights has just had a big update to version 3.8, most notably bringing support for the popular NinjaSMS texting app. NinjaSMS users, make sure you're running the latest version of both apps, and enable Light Flow in the settings menu.

Other changes to Light Flow include a tweaked notification system, in which persistent notifications are more, well, persistent. Devices running older versions of Android will have to do without persistent notifications, for reasons which the developer does not list. Users of later versions of CyanogenMod and ROMs based on CyanogenMod should see fewer issues in version 3.8, and more complete support for Google Hangouts (including the myriad types of notifications within the app) has been added.

Light Flow is downloadable on Android 2.2 or later. The free version is limited in its notification support and speed, while the $2.49 paid version supports over 600 types of notifications for apps and settings.

What's in this version:

Reworked persistent notifications
Removed persistent notification for older versions of android
Reworked how to display apps listed where accessibility is not on
New "clear notifications style" of "phone unlocked"
Changes to get working with latest CM roms
Added support for Ninja SMS thanks to the great Ninja Apps team - requires version 1.4 of their app and the light flow option enabling.
Support for more Hangout notification types

    It'd be nice if they would include customizable ringtones too, not just missed call.

    • Andrew

      I'm adding that. The development build has about 50% of the code ready for this and I'd planned to try get it into version 3.8.0, but after chatting to the ninja devs we decided to go for a launch of the new support at the same time

      • Sokudoningyou

        If you do, I will be delirious with joy. I'm stuck using two different apps to get everything I want currently. All Lightflow needs is the ringtones and I'm good.

        Well, that, and maybe an ability to remove notifications I don't need, but I'm just happy to get ringtones.

  • Bryan Pizzuti

    This is an absolute MUST with the wonderful notification home-button on LG phones.

      Or the razr hd, its the entire speaker grill.

    Does anyone else use Light Manager instead of this app?

    • Ranger666

      Light Manager is so much better than this. Light flow seems to have a never ending bug of some type. I have never had any issues with Light Manager.

        Been using LightFlow since I got my Galaxy Nexus and didn't encounter any bugs yet.

        Care to elaborate?

        • Mohammad Danish

          Some of the problems I had with Light Flow were occasionally the notifications wouldn't go away until I opened the Light Flow app itself. And also it would keep my device awake for 10+ hours at times, preventing it from entering deep sleep. They might have fixed these bugs but they were quite annoying to make me go look for a replacement.
          Light Manager has been working perfectly for me since day one.

            I didn't encounter those bugs but thanks for sharing!

            Have you tried contacting the developer about these? I sent some request for additional app support before and he was very quick to reply.

      • Andrew

        Lightflow uses a totally different approach to handling notifications which means that it'll work on non-rooted devices unlike light manger for most notification types. I am in the works of adding an approach that will allow root users to get more control in a similar way to light manager, but from my initial development tests I'm hoping it should be more battery efficient as behind the scenes my approach to it will be quite different.

  • Rod

    Explain why I would need this on Cyanogen? Custom color and blink are built in. How is this better?

    • Jezz_X

      because it allows custom blink speeds and patterns and custom vibrations and other things as well as greater support for different things in one app instead of just 1 for each app.

      But I agree the CM built in one is enough for me

      • Rod

        I read a little on the website and thought that notification rotation was the killer feature. I'll wait

    • Andrew

      I think the main differences are that lightflow allows cycling around notifications colors or deciding which apps are most important to you and using a priority system for displaying which notification type you think is most important as opposed to just the most recent notification of the highest android priority.

      That and you can set custom notification settings for contacts for missed calls, SMS, whatsapp and a few others.

    I'm interested by this app, but I fear it will be a resource hog (battery, memory and/or processor). Can anyone confirm or deny that?

    • Hothfox

      It doesn't even show up in my battery stats, so it must be pretty light.

      • s427


        I must say I'm more concerned about memory usage. My (stock) launcher seems to be constantly restarting lately...

        • Hothfox

          I've never really worried about my stats too much. Things are pretty zippy on my GNex. Ignorance is bliss, I guess - I haven't had any complaints about my general usage, so I think it's safe to say all my apps and ROM play nicely together. I do have it overclocked to 1350mHz, but it doesn't spend much time there.
