Hey, I bought LockInfo 5, Intelliscreen 6 and Bulletin and tested them all.
Everyone of them has some good and some bad aspects.
LockInfo 4 with its InfoScreen and Plugins is really the best Lockscreen and Notification Center application, but unfortunately it's not compatible with iOS6.
LockInfo 5 is a new way of controlling you lockscreen. You have widgets and notifications displayed separately on the lockscreen. The notifications can be displayed all together or individually. With LockInfo 5 you can get your informations without leaving the lockscreen, which makes it very useful. You can view your calendar entries and their notes without opening the calendar app in the lockscreen. You can do the same with RSS feeds, Emails and twitter. The negative points of LockInfo 5 are, you cant remove or change the weather widget and the "slide to unlock" part. You can install 3rd party tweaks to remove it or make it invisible, but note that it will not adjust its height. Another drawback is, the Notification Center isn't like in the lockscreen, which I don't understand, but It's not coherent. Another negativ point is you can't display widgets and notifications on the lockscreen together, you have to chose whether the one or the other.
LockInfo 5 costs $7.99, you had the chance to get it for $3.99 like I did. It's a free upgrade for LickInfo 4.
That was the reason I tried IntelliscreenX 6. It hasn't changed a lot since the first first version, but improved and added some small features. It's like the original Notification Center. You can also swipe it to the lockscreen and swipe it off the lockscreen just like the notification center on your homescreen. I works fluently and you can have "screens", which are widget all over the screen in the Notification center. You have the Notification center and the screens for mails, Facebook, Twitter and RSS feeds. I personally don't use these widgets and use the Reeder app, so I disabled all screens. I like the fact that you can use the camera grabber on the lockscreen to invoke the camera. A unique selling proposition which I miss in LockInfo is the "Top Shelf". You can put widgets in the Top Shelf above the first widget and unveil it with a swipe. You have also a "QuickSettings", which allows you to activate and change system functions like turning on and off Wi-Fi, Data, Rotation, do a respring just like SBSettings. You can also integrate SBSettings toggles in QuickSettings. Maybe some of you know "Messages+", a tweak which allows you to quick replay messages without opening the messages app. It is integrated in IntelliscreenX for free as a Add-on. In comparison to LockInfo 5 you can remove, hide and change the weather widget, but you can't remove or change the "slide to unlock" part. You can also install 3rd party tweaks and Winterboard themes to remove it or make it invisible, but note that it will not adjust its height.
Intelliscreen 6 costs $9.99, which is also a lot and even more expensive than LockInfo. Unfortunately it's not a free upgrade for the previous version.
The third contender is Bulletin. It's a lightweight version of IntelliScreenX 6. It has almost the same functionality, without the widget screens, the Top Shelf function and no Messages+. But Bulletin offers other also mentionable features which I personally miss in LockInfo and IntelliScreenX. First of all you can chose and customize you wallpaper the way you want it. You can chose one or change the color of the existing wallpaper or even add blur and other effects. The are also functions like swipe to unlock, which allows you to swipe the lock screen away to unlock your device, which is pretty awesome.
You can also swipe to delete notifications, messages etc. individually.
A negative aspect is, you can't use the the camera grabber with the Notification Center on the lock screen. You can see the lock screen camera grabber, but you can't also use it if you turned on the swipe to unlock functionality. It's also not possible to use SBSettings without integrating it in the Notification center and you can't use widgets like WeeSearchPro, where you use the keyboard to write something.
Bulletin costs just $0.99 and is the cheapest contender, but has it's own usp's.
I often get the question: "which one is the best?", and my answer is always: "I can't decide which one is the best, just which one fits the best to me". You have to ask yourself what you need and to decide what you want.
The best solution would be LockInfo 4, which allows the user to set and customize almost everything, and also has plugins and integrates widgets, but because of it incompatibility with iOS6 you have to chose one of these.
- If you want to have a lot of control with a fixed lock screen, built-in viewer options, but with a little customization, then pick LockInfo 5.
- If you want to have a lock screen,(which you can swipe off) with a lot of customization and swipeable screens for social media, mails and RSS feeds, then choose IntelliScreenX 6.
- If you just want the notification center in you lock screen with many small design features, then choose Bulletin.
