Ok Pepe Silvia done, even though there's more to share, might do a John Deere II 😂

Informational 🧵s below

It was interesting to see how many different apps John Deere has & learn that they do way more than "just tractors"

All their apps are also built differently. There's a 317 MB "Visit John Deere" app that's almost all unity (stripping symbols would save ~60 MB)

Again, an app that is designed for large tractor usage might be downloaded in less than ideal network conditions

There's some relatively low hanging fruit that would probably make user's lives easier, regardless of their network connectivity

Of the app's 412 MB, 112 MB are html files. Assets are 214 MB

The HTML seem to power web views to different tractor models, but there's a lot of duplication

Between handling duplication and image compression, TractorPlus could shave 79 MB, reducing app size by ~20%

Ok so what about TractorPlus?

Well they're actually shipping a ~112 MB of html files in their en.lproj, which we initially attributed as a localization even though it isn't really

App size is crucial in areas w/ limited connectivity. Every byte counts more

Ops Center manages "equipment & farm operations" globally — possibly used in remote areas

If John Deere took Tinder’s approach, they’d cut l10n from 113 MB → < 20 MB, reducing app size by a third

Let's start with ⚙️ Ops Center

They support 33 languages. The largest l10n is 5.6 MB for Tamil. The smallest is for English at 2.6 MB

Ops Center also supports languages like Bengali, Croatian, Kazakh & more. Clearly more than our initial thought of "American tractor company"

Re John Deere our thought was "aren't they an American tractor company? Why is half their app localizations?"

And then you see that despite having similar l10n sizes, Ops Center supports 33 languages, but TractorPlus only supports english?

Something has to be going on here...

How the Tinder iOS App reduced the size of our localizations by 95% using Emerge Authored by: Maxwell Elliott and Connor Wybranowski

Firstly, apps like FedEx (160 MB l10n) or Garmin Connect (90 MB) inefficiently use localizations

Tinder recently wrote how they used Emerge to reduce size of l10n by 95%
medium.com/tinder/how-t...

Airbnb did a similar optimization - we'll link to a few 🧵s at the bottom

Some context - we were poking around our localization data and John Deere's "TractorPlus" & "Ops Center" jumped out

🚜 TractorPlus is 412 MB - 115 MB (32%) is l10n

⚙️ Ops Center is 276 MB - 114 MB (42%) is l10n

So why did this jump out?

Ok, time for a bit of a rabbit hole

...or should we say... Deere hole 🤦

p.s. l10n = localization

Emerge Tools | Threads Deep Dive Emerge Tools analysis of the Threads app

You can check out our deep dive on Threads here 🧵 www.emergetools.com/deep-dives/t...

When Threads first released in 2023, it heavily leveraged existing IG code

While there are also many shared IG modules in Edits, it doesn't seem to be the same extent as threads 🧐

A general breakdown

Total install size - 131 MB
Main app target - 103 MB
Assets - 11 MB
Localizations - 8 MB

We heard that Meta released a new editing app yesterday 👀

Compared to other top editing apps, Edits is actually much smaller in size

this was actually first order of business when we joined @bsky.app 🙂‍↕️ bsky.app/profile/emer...

And ICYMI, here's last week's announcement about how our size analysis treemap can parse jsbundles more granularly now 😌 bsky.app/profile/emer...

Using the same example from last week, stripping the debug info means Shopify could cut 9.5 MB from their app

The debug info in these files are meant to give you better stack traces for errors, but it doesn't need to be shipped to prod because you can provide it separately to crash reporters (enabling Hermes source maps will create a separate file for you) 💡
