An Apps Experiment
Introduction
This is an experiment I performed out of curiosity, and I have a few big disclaimers at the bottom. Basically, I've seen a lot of comments recently about one app or another not displaying something right. Lemmy has been around for a while now and can no longer be considered an experimental platform.
Lemmy and the apps that people use to access the platform have become an important part of people’s lives. Whether you are checking the app weekly or daily, and whether you use it to stay up on the news or to stay connected to your hobby, it’s important that it works. I hope that this helps people to see the extent of the challenge, and encourages developers to improve their apps, too.
How I did it
I wanted to investigate objectively how accurately each app displays text of posts and comments using the standard Lemmy markdown. Markdown is a standard part of the Lemmy platform, but not all apps handle it the same. It is basically what gives text useful formatting.
I used the latest release of each app, but did not include pre-releases. I only included apps that have released an update in the last 6 months, which should include most apps in active development. ~~I was unable to test iOS-exclusive apps, so they are not included either. In all, 16 apps met the inclusion criteria.~~
I also added Eternity, which is in active development, although it has not had a recent update. I was able to include several iOS apps thanks to testing from @jordanlund@lemmy.world – Thanks, Jordan! This made for 20 apps that were tested.
Each app was rated in 5 categories: Text, Format, Spoilers, Links, and Images. I chose these mostly based on the wonderful Markdown Guide from @marvin@sffa.community, which was posted about a year ago in !meta@sffa.community (here).
I checked whether each app correctly displayed each category, then took the overall average. Each category was weighted equally. Text includes italic, bold, strong, strikethrough, superscript, and subscript. Format includes block quotes, lists, code (block and inline), tables, and dividers. Spoilers includes display of hidden, expandable spoilers. Links includes external links, username links, and community links. Images included embedded images, image references, and inline images.
Thanks to input from others, I also added a test to see if lemmy hyperlinks opened in-app. There was a problem with using the SFFA Community Guide that caused some apps to be essentially penalized twice because there was formatting inside formatting, so I created this TEST POST to more clearly and fairly measure each app.
In each case, I checked whether the display was correct based on the rules for Lemmy Markdown, and consistent with the author’s intent. In cases where the app recognized the tag correctly but did not display it accurately, that was treated as a fail.

I Love Lemmy Apps (and their devs)
Lemmy apps devs work very hard, and invest a lot in the platform. Lemmy is better because they are doing the work that they do. Like, a LOT better. Everyone who uses the platform has to access it through one app or another. Apps are the face of the entire platform. Whether an app is a FOSS passion project, underwritten by a grant, or generating income through sales or ads, no one is getting rich by making their app. It is for the benefit of the community.
This is not meant to be a rating of the quality or functionality of any app. An app may have a high rating here but be missing other features that users want, or users may love an app that has a lower rating. This is just about how well apps handle markdown.
This is pretty unscientific
You’ll see my methodology above. I’m not a scientist. There is probably a much better way to do this, and I probably have biases in terms of how I went about it. I think it’s interesting and probably has some valuable information. If you think it’s interesting, let me know. If you think of a better way, PM me and I’d be happy to share what I have so you don’t have to start from scratch.
My only goal is to help the community
I do think that accurately displaying markdown should be a standard expectation of a finished app. I hope that devs use this as an opportunity to shore up the areas that are lagging, and that they have a set of standards to aim for.
~~I don’t have any Apple things~~
~~Sorry. This is just Android and Web review. If someone would like to see how iOS apps are doing, please reach out and I’ll share how we can work together to include them.~~
I threw together a quick batch of test units for anyone interested.
To fully pass this test you should see 5 images, 2 of which are animated smoothly.
Edit: Added a splash of colour to the SVG example.
Princess Ruto gif animated
Princess Ruto webp animated
Cat Interlaced PNG image
Cat AVIF image
Girl SVG image
For the record, the SVG is (edit: no longer) only black and transparent so it is probably OK if you see a blank rectangle in pure-black dark mode.
Thanks for pointing that out. I updated the image.
Great!
Try video too. I wrote about instances handling video uploads but you can just embed any video file from any site like an image.
This WebM has audio and is quite short:
This WebM has a lower bitrate and no audio:
A longer WebM with audio but small enough to be uploaded on most Lemmy instances (if you so choose):
MP4 (H264+AAC), no alt text in Markdown:
I don't even know if they are supposed to play as GIFs (automatically, no sound, looping) or on demand; client implementation varies.
Oh great idea. I would of used your SVG image but I had spent roughly 4 hours writing a script to change black into rainbows after seeing your original message haha
