Hi Locker - lockscreen replacement. You can use a separate wallpaper that changes (like Muzei) that blurs when you have notifications. My favorite one so far.
hovernote - sticky note that hovers above your current app. Can be hidden temporarily as a button to the side or in your notification tray.

get a different lockscreen....i really like HiLocker (https://play.google.com/store/apps/details?id=mobi.appplus.hilocker&hl=en) has alot of features, or try to google a lockscreen that lets you put widgets of your choice in there.

I was using Hi-Locker for a good while, then after I rooted my phone and installed CM13 I have just been using the stock notification screen. But Hi-Locker was my go to for quite some-time. In fact, now you got me wanting to reinstall it. Thanks!

What you need, is a custom lock screen that supports widgets. So you'll place widgets on the new lock screen so they appear while the phone is still locked. Not sure which one to recommend... but that's the idea. The lock screen generally is for notifications and such so you unlock the device to view them. Having interactive apps like calculator requires a 3rd party lock screen with that functionality. You'll probably want to disable the standard lock screen so you don't unlock to have to unlock again.

One that is pretty close to this is hi locker which gives you quick "bubble" links to apps that you can change to your own preferences.

I use for about a month Hi Locker.

I was looking for an lockscreen app to give me the power to see my wifi status, notifications, gsm signal when screen is locked. Samsungs stock lockscreen app is shitty for my needs.

Hi locker have never give me any errors or phone freezes. Everyone should try.

I recommend either Hi Locker or Smart Lockscreen

Smart Lockscreen= http://forum.xda-developers.com/android/apps-games/app-smartlockscreen-android-enjoy-t2919989

I actually use hi locker. I experience no lag when I turn on my screen. It has built in notifications

It kind of reminds me of Hi Locker for Android

HI Locker has smart lock features built-in.

Hi locker has a Lollipop esque setting, there's also a few lollipop lockscreen apps on the play store.

Try Hi locker. I've used it in the past and it should do what you're looking for.

Third-party locking apps (ex.: Hi Locker) implement smart lock based on the WiFi network your phone is connected to.

Im using HiLocker and it's really good and beautifully designed.
