For a long while, I've wanted to build an app that'd make it easier to evaluate and extract data from my runs, and now it's finally coming alive. 🌱 Meet Runny, which will have great Shortcuts actions for runners! 🏃‍♂️

I rarely post personal news here, but got really happy today running my third half-marathon 😊 21,1km in 1:52:30 for a pace of 5:20/km! Still haven't beaten my 2022 PR (5:16/km), but lots better than my last year's time (5:30/km). Onwards to next year, with a couple 10k races in the meantime 🏃💨

Missed last week, but I'm back now! Here's a new shortcut I'm really happy with: visualize your sleep stages as a stream chart! Shortcut link: www.icloud.com/shortcuts/ebc0... I also built a free version that plots your recent deep sleep amount: www.icloud.com/shortcuts/e296... Hope you like it!

I know we're in beta season and all, but this isn't acceptable. More than 50% of my 128gb iPhone 16 pro storage is lost to iOS. This is unreal. If iOS *really* needs this much space, Apple should never sell 128gb phones.

It's got an entirely new interface completely written in SwiftUI! This new codebase is going to make updating it a lot easier in the future!

One of the major gains is that charts are now drawn using Apple's native technologies resulting in not only charts that are more beautiful, but also more customizable. #indiedev #ios #shortcuts

Good day today: ran my second half-marathon! #21k in 1h55m43s! Trained using the #Runna app and it was excellent, lots of different workouts, mixing tempo, hills and long runs. Definitely gonna keep using it 😊 #running

The adaptation to #LiquidGlass continues here for @chartyios.app! As @davidsmith pointed in the latest #UnderTheRadar episode, a lot of this is removing custom code in order to get the advantages of what the system is offering.

Ok, let’s do this: here’s @chartyios.app 2.0 compiled for iOS 26! Really happy with how easy it was to get it running, but still needs some work on my custom controls 🚀

Very interesting! I’ve been experimenting with using LLMs to explain Charty’s shortcuts for next release, but I’ve been using the Get File of Type action to convert the shortcuts to json 😊

Rodrigo Araújo @rodrigo.rapptor.dev · 25/04/2025

Some news on the @chartyios.app 2.0 front! - Updated the series and values selection making it easier to distinguish between them - Revamped the Tutorials view to make it easier to onboard new users and explain examples Hoping to get at least 10 examples there #iOSDev #BuildInPublic #SwiftUi

More than 5 years since launch, I’m updating the examples on @chartyios.app 2.0. Here’s the current list! There’s some favorites (Weight Analysis) and some updated ones (Data from CSV). Also, there’s new ones such as a Reminders’ tasks tracker which can be modified to work with OmniFocus or Things 😊

I’ve tried creating a white background invite to see how the elements would work, but it fades to gray to keep the dark palette. I know Apple has a solution for this, this is just me trying to understand what I might be 😅

GitHub-style scatter charts will look even better in @chartyios.app 2.0! Been using these to get more consistent with my exercise routine. Light green are runs 🏃‍♂️, and dark green, CrossFit workouts 💪 Also noticed I haven’t exercised on Saturdays for a while, gonna try to change that next weekend 😊

Since I’ve purchased the Steamdeck, I’ve been playing a lot of Fields of Mistria. I’m completely baffled by how good this feels and how much of a stardew valley 2 vibe it gives. Almost everything seems improved and easier to do, while keeping the game loop tight and engaging. 10/10!

I understand there’s a fine line between copying and inspiration (that line that meta usually blows by), but this is a very noticeable rip-off of Fall Guys. It’d be a bad thing to *allow* this on the App Store, but Apple is *promoting* it on the Brazilian App Store.

If I had to suggest one app that made a difference to me in 2024, it’d have to be One Sec. It’s saved me hours of doom scrolling 😅 Its charts are really good at showing when my habit started to change throughout the year. App Store: apps.apple.com/br/app/one-s...

Here’s a cool shortcut using @chartyios.app and Overcast by @marcoarment.bsky.social! Just take a screenshot from your 2024 recap on Overcast, and run this shortcut: www.icloud.com/shortcuts/ca... It’ll extract data from the image and create a donut chart of what you most listened to!

Dear #SwiftUI #Swift devs, has anyone ran into this weird SwiftCharts legend bug? It's trying to align the items as columns, but seems to not be taking line 2 into consideration before positioning line 1. Here's the code to reproduce: gist.github.com/rodrigoarauj... Please share for visibility :)

From the iPhone finalists, I’ve used Runna to train for an 18k race and it’s awesome, but I’m definitely rooting for @tripsy.app from my fellow indie Brazilians @thiagosanchz.bsky.social and @rafaelks.com! It is an *awesome* trip manager and it’s helped me organize all of my trips since 2022!
