I found a Crypto Widget app this morning that even allows you to put a widget on your homepage with Crypto currency and market of choice, really simple and great app. It was this one: https://play.google.com/store/apps/details?id=org.phauna.litecoinwidget
Depends on where you are viewing the prices, and the "real-time" prices only matter if you are a day trader. If you plan to hodl, you don't need pricing updates like that.
But if you insist, I can only assume you bought LTC on coinbase. The default interval is 1 hour (it is the midway point of all the time frames they offer). You have to use a different exchange/app, if you want to view small time intervals.
For exchanges, I prefer Brittex, with/without the coinigy overlay. They offer intervals up to 1 day, and all the way down to 1 min. But like I said this is for day trading, do not do it unless you have experience day trading in the past. Especially now with the "volitile" market, as you put it.
If you want an app, I suggest this widget for android. You select the exchange you want to follow, then LTC, select the colors (if you wanna be fancy), then the interval (1min to 120mins0, and finally hit "Let's Go Already!".
Due to the nature of being, as some would call it, "an early adopter" you can't get "real-time" updates. The reason the stock market is able to get real-time updates is due to the fact that billions, BILLIONS of dollars have been spent on the network infrastructure to facilitate that.
Crypto doesn't have that. Yet.
I really like this one for Android (not sure what OS you're after):
ETH from different exchanges, in different fiat/pairs, etc. https://play.google.com/store/apps/details?id=org.phauna.litecoinwidget&hl=en
I personally use Digital Currency Widget. Its got options for pretty much all the cryptos/exchanges. https://play.google.com/store/apps/details?id=org.phauna.litecoinwidget&hl=en
this one is pretty cool too, android widget https://play.google.com/store/apps/details?id=org.phauna.litecoinwidget&hl=en
