0 - I have not used any of the following in real world, but hopefully helpful pointers to look at.
1 - what is your language preference/strongest
If wanting to stick with c#/.net side of things, look toward Xamarin. Build one logic core, apply platform specifics for android/ios where needed.
But will need apple machine to build the ios version.
2 - Web App with offline functionality Quote: clearing your browser history or cookies will mess them up good
Is this a real concern or over thinking?
I would expect offline data to be stored in the local storage api and not as cookies. Yes this can be cleared, but I would check what the default settings are for clearing.
If want to give the "feel" of an app, then maybe look at wrapping it in electronjs

I'm not sure.
I know someone who clears everything by default.
I know she's an exception, but it still worries me.
Xamarin looks like it could be a valid option.
Or maybe a web app with offline functionality, because it'll be cheaper for the client

You don’t “need” a Mac. You can use a hackintosh running under VMware. If your dev machine has enough memory, you can run the hackintosh on same machine as VS.

Try Xojo. It allows you to write native code for all popular platforms. That is something that not even MS or Java can do.

Looks like low-code and the code you have to write is VB.NET.
I'm a bit allergic to low-code since my last experience with it (no source control, the code you have to write becomes a lot more difficult to write because you need to know the framework, the drag'n'drop "code" takes ages to click together, the database had no query language...).
I'll put it on my long-list though.

Uno Platform is what you want. It supports all phone and desktop platforms from a single codebase.

Google's Firebase real-time database is designed for exactly this particular scenario.
You don't have to do this, but if you combined it with something like Flutter, you've got a platform for building xplat mobile apps, and (coming soon) web apps on top of it too.

Looks very cool!

Yes. Xamarin Forms using Visual Studio 2019 on Windows, with a Mac Mini or other Mac on the network that you can connect to from VS2019 and if needed, VNC into. The single Xamarin Forms solution creates iOS, Android, and UWP (for Windows) projects. The UI code is written once (though you can include native UI code if and when necessary, which is rare or non-existent), and shared between the OS-specific projects. The time-to-delivery is better than other development platforms when one considers equally skilled developers in each platform.
I use that setup and it works like a charm. The caveat, which is true in about any development environment, is to use the tool as it was designed to be used. Native mobile apps (stateful) are a wholly different architecture than web apps (stateless). In fact, they are more like WinForms apps than like web apps.
You can build the WebAPI code in the same project, so if there is an Internet connection, the data uploads. If the connection is not there, you can save the data locally, and automatically upload when connected.

Couchdb builtin offline ability and can sync when you get a connection.

I've been using Ionic (ionicframework.com) for several years. It works well if you want to target Apple, Android and web all with one code base. It also supports Progressive Web Apps (offline web applications). I've had clients that did not want to pay for an iOS developer, an Android developer and a web developer but wanted it on all 3 platforms. Obviously, having one code base also makes it easier to maintain.

Front end: PhoneGap, Xamarin, Flutter
Flutter might be your best bet here, but because it's so new it's a bit of a pain to find certain kinds of libraries.
Offline w/ sync, backend: PouchDB, TurtleDB, RXDB

I may get flogged depending on how y'all feel about javascript, but I have found react-native (if you want a quick boost to get you going, react-native w/expo) to be very helpful.
I started looking into it in August and spent about 4 weeks just tinkering and learning. A simple offline app could be constructed much more quickly and deployed, depending on how well you like javascript. I actually think expo also has a method to submit to apple if you lack a Mac.
Best of luck.

PWA is the way to go.
You can take any of the Microsoft website templates (or anything else for that matter) and make what you need. Then you go to pwabuilder.com and get a manifest/service worker to add to your code.
At the same site you get everything you need to submit to the Windows Store, Play Store and App Store.
Here is part 2 of a 25 part tutorial about everything you always wanted to know about PWAs:

Been catching up on my CodeProject daily news and came across your question.
I did some work a couple of years ago on a single-page application written in ember.js and we had a requirement for the application to work in an "offline" mode. Once the user had logged onto the system they could enter offline mode and only offline modules would be available.
We used node.js to host a local rest api that would then be able to access local resources to save the relevant messages/data since we had the same issue with localstorage being cleared and couldn't have our messages disappear. The SPA was then also locally hosted and communicated with the node rest api (we used restify).
It appears as though node.js is available for mobile devices now also so perhaps you could consider something along the lines of a locally hosted web-site that uses the rest api as a store-and-forward mechanism.

The daily Bing image[^], of course 
I have an app that puts the image on my desktop's background.
This particular one made me scratch my head.
For a minute there I thought the building had a sticker or a painting of trees on the concrete below it.
The thought even crossed my mind that this was some very poor PaintShop job.
Then I realized there's no concrete at all and what I'm looking at is just the background under a bridge!

The answer would not be of any help for you, because everything I write here is a lie. William Shatner probably talked many AIs into suicide with this one alone.
