Can anyone recommend best portfolio app to keep track of altcoin? and please mention why it is best.

Delta!  Better than Blockfolio, not so laggy. Just perfect for everyday use. I use it for more than 2 months now.
You can set alarms, you get a daily rapports on your profit\loss. Nice and clear interface, easy interaction, user friendly.
Supports many exchanges. You can add ICOs, fiat. Great team and support.
Here is their ANN thread https://bitcointalk.org/index.php?topic=2260251.0

I am, using blockfolio. It has all the coins I need on it, news and markets.

Coin Portfolio for me...but also blockfolio for the coins that are not in the first one.

Coinstats seems to work fine for me through iOS. I do like that it gives me a "pump" notification each time a coin jumps up a significant price within an hour

Try Blockfolio or Delta

cointracking (I also reviewed their site on my website: https://bitcoincashback.net/cointracking-review.html)
delta
blockfolio

I found cointracking.info to be the best for my purposes. It keeps track of realized and unrealized gains for the purposes of accurately paying taxes. It doesn't have some of the fancy graphs and charts of the other offerings, but i was only going to manually enter all of my transactions into a single app, and this was the only one I found with this feature for free.

I really prefer Delta.. Blockfolio has that "classic" look that you always see in screenshots but the layout of info is much easier at a glance with Delta.. both have decent alerts but Delta gets my vote.

I never tried Delta of the mentioned apps but you should definitely try Cryptonaut!
You can enter your holdings of each coin, there is a nice dashboard and you can create price alerts.

But I think, it's a matter of taste. So, you should try all of them and choose the one you like the most :)

I’m using Blockfolio, but might try out Delta.
