We follow the principle of doing one thing well instead of all things mediocre, so we use 2 solutions for what you asked. As others in the thread, we do use Tandoor, but only for Recipes and Meal Planning. It does this execeptionally well, but the shopping list part is fitting to our style of shopping.

As a shopping list, we use David Shays Groceries / Specifically Clementines. Why?

• It works offline when you are in one of those huge buildings that work like a faradays cage and you do not have reception anymore.
• It lets my partner attach a picture to a list item, so I can find that specific cheese when I am standing clueless in front of those shelves with 500 different cheese brands and that helps me find the right item before the shop closes.
• It works exactly the way we shop. We always arranged items in the order they are in the shop when you work through the shop from entry to exit. That is super efficient.
• It supports aisles. That means your items are assigned to an aisle. The super cool feature here is, that you can rearrange the isles for each shop. Veggies are at the entrance of Shop A, but at the middle of Shop B? Just arrange the isle for Shop A to the start of the list and to the middle of Shop B. Since all items are connected to an isle, they move with the aisle. This way you never have to turn around in a shop to get “those other things”. You just walk from entry to exit in one line and be done with it.
• With this software I never forgot to buy something I did not find in Shop A. How this software does it is that you create list groups that contain lists for every shop that fits. For example you group food shops together, or shops for gardening stuff. Within the list groups, you have your items. And when putting an item on a list, you can select on which list it should appear. Now when you put your favourite cheese on the List of Shop A and B and you bought it on Shop A, it gets ticked off on Shop B too. Or the other way round, I think you get the idea.
• I have to repeat that it works offline. A shopping list is useless if you can not use it when you are shopping.
• Accidentially ticked off an item because, well… touchscreens and you do not know what it was? No problem. Ticked off items just move down that list and you can pick it up again. With other apps stuff just disappears or gets send back to the global item list and now you do not have any idea what you missed. Not so with “Specifically Clementines”.
• It never let us down. It always worked, whether offline or online without any hiccups.

There is more, but this post got too long already. It also has User Management, Permissions and Live Sync. Yes, my Partner can see live when I tick of items on the list and can put stuff on the list while I am shopping :-)

Everything in that software feels like it was created by a person that goes actually shopping.

It has a very good web interface (which also has the offline mode AFAIK) and a very good Android App.

Does it look fancy? No. Has it everything we ever searched for in a shopping list app? Absolutely!

Could it be an MTU issue? Networking van be weird if packets get fragmented unexpectedly, but I see this mostly for IKEv2 and other VPN Services. Try to lower your MTU on the WAN side Maybe?

I would absolutely look into it. Many years ago when Docker emerged, I did not understand it and called it “Hipster shit”. But also a lot of people around me who used Docker at that time did not understand it either. Some lost data, some had servicec that stopped working and they had no idea how to fix it.

Years passed and Containers stayed, so I started to have a closer look at it, tried to understand it. Understand what you can do with it and what you can not. As others here said, I also had to learn how to troubleshoot, because stuff now runs inside a container and you don´t just copy a new binary or library into a container to try to fix something.

Today, my homelab runs 50 Containers and I am not looking back. When I rebuild my Homelab this year, I went full Docker. The most important reason for me was: Every application I run dockerized is predictable and isolated from the others (from the binary side, network side is another story). The issues I had earlier with my Homelab when running everything directly in the Box in Linux is having problems when let´s say one application needs PHP 8.x and another, older one still only runs with PHP 7.x. Or multiple applications have a dependency of a specific library when after updating it, one app works, the other doesn´t anymore because it would need an update too. Running an apt upgrade was always a very exciting moment… and not in a good way. With Docker I do not have these problems. I can update each container on its own. If something breaks in one Container, it does not affect the others.

Another big plus is the Backups you can do. I back up every docker-compose + data for each container with Kopia. Since barely anything is installed in Linux directly, I can spin up a VM, restore my Backups withi Kopia and start all containers again to test my Backup strategy. Stuff just works. No fiddling with the Linux system itself adjusting tons of Config files, installing hundreds of packages to get all my services up and running again when I have a hardware failure.

I really started to love Docker, especially in my Homelab.

Oh, and you would think you have a big resource usage when everything is containerized? My 50 Containers right now consume less than 6 GB of RAM and I run stuff like Jellyfin, Pi-Hole, Homeassistant, Mosquitto, multiple Kopia instances, multiple Traefik Instances with Crowdsec, Logitech Mediaserver, Tandoor, Zabbix and a lot of other things.

Oh wow! That looks like a pretty unique experience. I have a pen, indeed! Thank you very much :-)

I always miss Demos for games, but totally forgot that on Steam you can refund within the first 2 hours of gameplay. It should not hurt if it´s used rarely. I can not figure out yet if Slay the Spire is for me (for some games it is pretty clear when reading about them), so this one might be a good opportunity to test it out.

I played Mini Metro on Android a long time ago… did not remember that I might have it on Windows already too! I think it was in a bundle at one time. Thanks :-)

Thanks for the suggestion. “Unfortunately” I grew up with those and know probably each one of them inside out, as they have been replayed multiple times over the decades. But I did not think about SCUMMVM and reading this I get the urge to Talk to Mr. Tentacle Guy again :-)

Oh cool. That looks like it might also be a battery saver and not causing too much excess heat in the tablet :-)

I love Traefik! When I started, I tried NGinx, but could not wrap my head around it. So I tried Caddy. Pretty easy to understand andI used it for a while. Then I had demands Caddy could not do ant stumbled uponTraefik. As you said, a learning curve, butfor me much easier than NGinx. I like that you can put the Traefik config inside the Compose files and that the service only is active in Traefik when the actual Containers are up and running. I added Crowdsec to my external facing Traefik instance and even use a plain Traefik instance for all my internal services also. And it can forward http, https, TCP and UDP.

That´s a good idea. A Sci-Fi setting is a nice change from the classic Civ theme. I loved Alpha Centauri back then, could not stop playing. This might scratch that itch. Thank you :-)

That looks sweet! I never heard about that, looks like a whole series. That´s on the list :-)

Oh yes! That one was fantastic. It´s been a long time. Wasn´t it part of the very first Humble bundle?

That´s quite a list! Thank you :-) I even have a few on that list and will try them out. I did not think about The Witness, but it´s worth a try. I did not finis it on PC, but it has some really hard puzzles in it that keep you occupied for a while at the same place without the need to move around a lot.

The Hexcells series is awesome, played through all of them (of course not through all the random ones in Infinite ;-)), but might be worth to try again on the tablet. I tried Tametsi (also a puzzler), but it did not scale with the High DPI screen and was super tiny.

Thank you for your feedback! I get the impression that it might work if used on a small scale when it´s not public. I guess I will have a new container soon :-)

I had a good laugh looking at the Video on Steam. I am not sure if this will help me to wind-down, more something I might rage-quit in the middle of the night and then need a coffee to calm down again :-> But it does look pretty fun. Thanks for the suggestion :-)

Oh yes, Dorfromantik! I have this on my radar for a while. It looks so lovely. I did not know about Townscaper, but that looks very chill too.

I have Stardew Valley already, never thought about trying it on the tablet, but that´s something I will do. I love this game, but only played it with Mouse & Keyboard so far.

Thank you very much for your suggestions :-)

One reason is because I can. And because of that, I tend to host things myself which I can. This generates cost and work to maintain it on my side and not for others. A few less users from our household on a public instance means more room for others who are just not as tech-savvy and have no other choice as to rely on public instances. So it is a mix of respecting other peoples time, effort and money and a part is just the nerd that wants to find out how it works and how it´s done :-)

Oh wow, that is a lot more usage than I can think of for all of us here, haha! Thank you very much. That sounds very promising.

Is Revolt an option, maybe?
