An Apps Experiment

Cross-posted from https://lemmy.world/post/18159531

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 @[email protected] – 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 @[email protected], which was posted about a year ago in [email protected] (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.

Results

Out of a possible perfect 10, 6 apps displayed all markdown correctly:

Alexandrite - 10.0

Connect - 10.0

Jerboa (Official Android client) - 10.0

Photon - 10.0

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.

    The above feels wrong but idk if Lemmy has a formal markdown spec. I haven’t had time to dig into it. This is what it looks like in Jerboa. If it wasn’t 6 AM I’d try to file a big report.

        This was over a year ago now Jerboa may well be in a better state now. I can’t remember specific bugs but they were frequent and serious enough to frustrate me, a professional software tester, enough to move to a different app.

    cross-posted

    Minor nit pick, but did you know that Lemmy has actual cross posting functionality?

    Either way, interesting study. This is the type of content that I Red er… Lemmy for, so thanks for posting. I use Voyager myself, being an Apollo refugee.

      Yeah, cross posting is another quirky Lemmy thing. AFAIK it just generates a new post with the same content, and also maybe varies by app. That could be wrong though: I’m not sure.

        AFAIK it just generates a new post with the same content

        Yup, that is exactly what it does. So if the original post is edited, none of the changes propagate to any of the crossposts.

        In my opinion, crossposts should embed the original post, not simply copy a snapshot of the content at the time the crosspost is made. That’s a Lemmy issue though, not an app issue.

      Ya I’ve only been able to cross post on the web UI. I’ve seen apps like Jerboa and Voyager at least show cross posting correctly, I just wish they made it easier to cross-post in app.

        Thunder allows cross-posting! It should follow the web UI implementation (where the body of the new post has a link to the original, plus the original contents in a quote block).

          Oh nice! That’s the one I’ve probably tried the least so I’ll have to give that one another go. (Not for any particular reason, I just got used to the UI of the first couple other apps I tried). Thanks for the good news!

    There are a lot of image/gif(?) posts that I haven’t been able to view either on the Memmy (Apple) app or in-browser with either Safari (Apple) or Google Chrome. I imagine it comes down to the file types as well as the lack of native hosting to standardize posts of different media types, but I’m not the techiest person to consult on that. One downside of the fediverse is the lack of standards for file hosting/conversion/displaying to ensure that all media can be accessed regardless of the browser/app (or, alternatively, the lack of an all-encompassing app for all devices [Jerboa sounds like the closest to this to me but it is not available for iOS yet]), as well as the self-funded nature of the instances commonly not having the budget to natively host multimedia content such as videos.

      Unrelated, but photon keeps randomly redirecting pages to what is previously viewed. It has screwed me over by making me post to the wrong community.

        I don’t understand what this means. There are no redirect calls at all in photon other than for /comment urls, and certain layouts.

          Not exactly redirect, but sometimes it just goes back to the previous page. Maybe something to do with window.history?

          It was a while ago. I haven’t used it after the incident (July 12)

    @[email protected] iOS testing, not sure how you score these so I just listed out the broken stuff.

    Arctic - Link opens in App. Headings fail, images fail, everything else looks fine.

    Avelon - Link opens in browser, not app. Manually went to test post. Bold+Italic fails (Italic works, not Bold). Table fails. Horizontal Rule fails. Spoiler fails. Everything else looks good.

    Bean - Link opens in browser, not app. Manually went to test post. Text formatting block fails so hard, it’s not even visible(!) Heading fails. Code Block fails, Inline Code fails. Links and Image work, but not inline, only at the bottom of the post. Table fails. Hotizontal rule fails.

    CheeseBot - Did not test. $2.99, no free version.

    Lemmios - Link opens in app. Everything looks and works great EXCEPT Spoilers.

    Mlem - Link opens in browser, not app. Manually went to test post. As with Lemmios, everything looks and works great EXCEPT spoilers.

    Remmel - Instant fail. No development in 2 years, unable to even add an instance or an account. Non-starter.

    Thunder - Hard to test. Lots of lag for some reason. Link opens in browser, not app. Manually went to test post. That being said, EVERYTHING worked. The lag may have been because I had just linked my account. Testing everything above, then coming back to Thunder, I found it fast and responsive.

    Voyager - Link opens in app. EVERYTHING worked. No notes.

        it does, but only if you use the autocomplete feature. it’s also a bit delayed without any indicator that it’s loading.

        if you type @gedal and wait a moment it’ll load @[email protected] to be selected:

          Compare the source of your comment to the one you’re replying to. Those are two different things. I’d argue it’s a workaround of anything.

          Yes, I’m not sure if that is meant to be a placeholder or a substitute for native user links. What it actually does is generate markup that converts the username into a web link, which is fine for most circumstances, but not ideal. A plaintext username should automatically link to the user. This creates an inconsistent behavior between posts depending on where (and when) they were typed.

          In other words, it’s a very helpful feature, but it is not recognizing and linking usernames.

            Actually that behaviour is very annoying to other platforms. Mbin for example can only link to the lemmy server this user is on and no longer the local profile of that user. Example: @ user @ lemmy.instance gets converted to [@ user @ lemmy.instance](https:// lemmy.instance/u/user so on mbin this does not open the profile of the user on the local server, but instead links the lemmy instance, so you leave your instance to view the profile.

            (spaces included so this won’t get converted to mentions, etc)

                Yes they are, but you have my profile on your server and you do not need to leave the server to view my profile… @ user @ lemmy.instance should link to https:// mbin.instance/u/@user@lemmy.instance and not to https:// lemmy.instance/u/user

                  I’ll have to try on desktop, in the app it isn’t very clear what exactly it’s looking at to see profiles.

              yeah exactly. On mbin it works this way and lemmy inserting the link breaks that. But it does it for communities in the community description sometime as well, though I don’t know if it is just a user “error” or a lemmy error

          What happens if you press tab or click on the suggested item at the point in your screenshot?

          For me, it inserts the link at the cursor position, but doesn’t replace the bit you’ve already typed, resulting in @gedal[@gedaliyah@lemmy.world](URL).

          Anyone else have this issue?

            on firefox, if i type @gedal and click or press tab once it replaces the text with [@gedaliyah@lemmy.world](https://lemmy.world/u/gedaliyah) . the behavior is the same whether i hit tab, enter or click the text.

              Ah, you are correct. It turns out that the issue I was encountering was a little more subtle.

              If I type all the way to @gedaliyah@ and click or press tab once it replaces only the second ‘@’, resulting in @gedaliyah[@gedaliyah@lemmy.world](https://lemmy.world/u/gedaliyah).

            Didn’t know it worked on reddit. Generally it seems necessary to require the space as it disambiguates headings from hashtags, and also makes the raw text more readable.

        In doing this I learned that there are “correct” but also “preferred” ways to use markdown. A heading should have a space after the # even though it is correct either way.

        These lines may be the same or different in different apps.
