PoC - When you have an idea of how to do something, but not sure if it will work, so you build some working model than can prove (or not) you idea...Once I had an idea how to 'clean' scanned images using math (standard deviation) and made a software to prove it...
Prototype - It's a working minified/simplified version of your product (software), that show the main functions and your ability to create it at the same time...Again, I once made software for WiFi modem and the company created the board (almost manually) and printed on a 3D printer a prototype of the case to show how it will look like...
Skipper: We'll fix it.
Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

A Proof of Concept is all about showing that an idea can work - not that it does, or it's complete, but that it can be done.
The big difference between a PoC and a Prototype is that even the worst Sales department can't sell a PoC...

I see what you did there.

I've had sales departments sell prototypes before - and it's a nightmare, because you have to support the damn things for years despite them not being production ready. 
But...a PoC is so obviously not ready to be used that no-one will buy it! One of mine was a huge pile of electronics housed in cardboard boxes with mains leads running out the back. (We did cut ventilation slots in the boxes to prevent them catching fire, and checked the slots with the British Standard Finger to make sure we didn't electrocute customers) No way was the customer going to buy that! (But he was willing to talk about £2M worth of software development off the back of it, since it clearly could do what he wanted it to, if in a rather "fire-hazard" kind of way...)

I think you are looking at a PROTOTYPE rather than a PoC, I would mock up a couple of screens with dummy data without any database connectivity, make the UI as good as possible as that is what is going to sell the idea.
You need to be a little careful here as the client may just keep asking you to add bits to the prototype until you find you have built the app (this has happened to me) and then will argue the cost once it is done.
I would also get the client to make a commitment to the cost of building the prototype. You may lose the client and save you business.

I think in these cases (see the various cautions in other posts on this thread), you best protect yourself by making sure you have a clear understanding of what the client expects.
1. presentation: does the client expect to see a certain UI mock-up, use of visual themes/styled, etc. ?
2. functionality: does the client expect to observe your app connecting to an existing database and performing CRUD operations ? Expect to see accessing internet/cloud and saving/reading/scraping, etc. ?
3. algorithms/performance: does the client expect to see you processing some data in a certain amount of time in a particular way with particular results.
4. Ui features ?
By knowing, as precisely as possible, what the client expects before approving/hiring/paying, you can then estimate what your time costs are in preparing the prototype, and negotiate with the client. Ideally, you are in a position to state what you will, or won't do, for a certain fee prior to any longer-term contractual agreement.
Of course, in the real-world things are not so clear-cut, and, in the past, I have negotiated a flat fee for a certain period of my time (full-time, paid by the month) specifically to prototype, with the understanding that the client, or I , can cancel at the end of each month.
Flexibility may be necessary on your part, weighed against how much you trust the client, what you know of the client's dealings with other developers. I once worked eighteen-months full-time based on a handshake with a CEO, no contract ... that's rare.
I tend to think of POC and Prototype ideas like this:
1. Proof-of-Concept: answers questions which ask: "Can this be done ?"
2. Mock-Up/Sketch/WireFrame: purely visual representation of a UI, or of a WorkFlow, or some form of Diagram of state behavior of an Application.
3. Interactive Prototype: working simulation of UI interactivity possibly using mock data, mock database, etc.
4. Functional Prototype: working simulation of the basic functioning of an application including accessing real database, processing real data, etc.

Aye, and, understanding the particular spherical aberrations, or generic concavity, or convexity, in the Client's mirror, as well as your very own: aye, there's the game

...from my iPad Air. Using Microsoft's Remote Desktop for iOS.
Fun. The screen's a little cramped, but it works.
I will say that MS has created a top-notch app for iOS with this one. It works out of the box.

Well, I would hope so.
It'd be pretty difficult to use if you had to leave it in the box.

This is winter.
It is cold
Acronis Disk Monitor reports a disk temperature of 98 degrees (F)
I put my hand up to the vented side of the computer case.
Nowhere near that temperature.
Ripoff
I used to use a previous computer to heat a bedroom in the winter. This was in a geographic area considerably south of here, but it did help; noticeably.
If that thing is generating that kind of heat, and the temperature of this room is so much lower, there ought to be some way that I can put the two together and help both my work area and the operating temperature of the disk.

"The Interview"
If NK had tried to squash it on quality grounds, I'd have had to applaud... Trite, predictable drivel with characters you want to throttle - if it hadn't been attacked it would have sunk (and stunk) without trace.

I saw it last week, at the end of 2014, and I agree it's a fun movie. Action, fun, some pretty funny jokes, all-in-all very entertaining!
And of course The Hobbit: The Battle of the Five Armies!
*Looking up which movies came out in 2014*
Oh yes, I also liked The Monuments Men, Noah and Fury.
Interstellar was quite nice too, but the end was a bit... Weird.
And I've seen two movies in theaters that I didn't like all that much: Jack Ryan: Shadow Recruit and Lucy. I wouldn't recommend them.
And then there's a lot that I wanted to see, but didn't.
