I agree with JSOP. Write it as a web app and run it on any device.

I was tempted to do an iOS app a few years ago for a new customer who elected to use iPads. I tried Xamarin with mixed results, and ultimately decided it wasn't worth the effort or the cost (you have to buy a developer license) for a single customer.

Instead, I just wrote up a document explaining how to create homescreen shortcuts to the two apps they needed. (which were already azure web apps anyway...on windows, they run in a browser container (to get the workstation name), for iPads, the shortcut contains a unique id for each iPad.) This has worked really well.

Now for a funny story. Back in 2002, our con man salesman promised a few clients that if they bought X today, we could give them a very deep discount (free) on our new web-based POS system when it came out the next year. Well, they bought, and I got started from scratch on our new web-based POS.

There were a few real challenges:
0: unreliability of the internet at the time meant that there had to be an off-line mode
1: responsiveness was a priority...long pauses caused by slow connections were not acceptable
2: integration with other local resources/systems (such as barcode/scanner input, imports/exports, images, etc.)

Based on those challenges, decided that the customers would need to host their own databases and webserver. They could host for their 80+ locations. The first 6 months were spent using classic asp and throwing together enough screens to test basic functionality. While it worked, the responsiveness issue (or lack thereof) was a deal breaker. Remember, this was almost 20 years ago and hardware/networks/browsers were much slower. Sigh | :sigh:

With 6 months until training, I separated the application into around a dozen modules which became ActiveX controls which were placed on a common webpage for all 80 something locations. Smile | :)
Not only was it web-based, it was auto-updating, it was available offline, and it connected to local resources. Most of all, it was responsive. Overall, it was a good application and I learned a lot doing it, but it was one of the first to be phased out (not resold) as it was not a market we (I) wanted to be in anyway. I still have it on a disk somewhere.

So, there's that example of a windows app masquerading as a web app but I have also done the reverse...running a web app in a browser control of a windows app. Sometimes, hybrid is the answer.
