I spent more time working on that than I initially anticipated today, but as a result, there is a new #TestFlight build waiting to be released for testers. 😆 As if the optimization was too little, I upgraded the app icon to a #LiquidGlass design as well. 😁
The new app icon for the Spark habit tracker, featuring a modern Liquid Glass design with a stylized flame in vibrant orange and yellow gradients, enclosed in a rounded square with a subtle shadow.

It requires some optimizations. However, in the playground project, it worked smoothly, so I suppose the new data schema used there might help. Yet another reason I have to migrate at last… 😬

It took me much longer than I wanted, but I started at last moving the new calendar view out of the playground project into Spark, and I must admit the results are great. 😊 Not only can you now easily go through history, but the calendar now scrolls naturally. 😁

Two smartphones displaying the "Write a Journal" habit in the Spark habit tracker app. The left phone shows a detailed monthly calendar view for September, highlighting completed days with blue circles. The right phone displays a summary view with a grid of completion dots for June, July, August, and September, emphasizing the 59-day streak and a 3-day streak type. Both screens use a dark theme with purple and blue accents.

I got an idea of how to express pauses in UI at last! That's why you can't see it in the attached video. 😆 You can see the alpha version of the new calendar view. It still requires a lot of work. Especially adding the mentioned pauses. 😅

I thought that Monday after vacation would be the worst, but it’s Tuesday that got me. 🥲 Nonetheless, I squeezed some #iOSDev work just before the #AppleEvent, and I’m ready to watch now. 😅

Apple Event Bingo" board, featuring a grid of iconic Apple product announcements and features, such as "iPhone 17 Announced," "Apple Watch Ultra 3," "120Hz Display," and "Pro iPhones Return to Aluminum Case." The iPad screen shows a colorful, interactive bingo game. In the background, a TV displays the Apple logo with a vibrant, swirling effect. The scene is set in a room with light-colored walls and a window.

I’ve just sent an update for a review! 🥳 I thought I’d never finish it, mostly because the internet connection where I am right now is bad, really bad, especially for Poland, where we have really good service almost everywhere. 😅

An email notification from App Store Connect addressed to Aleksander Stojanowski, stating that the status of the submitted app has changed to "Waiting for Review."

The only thing in all that that makes me just a little sad is that I needed to break my streak… 😔 But hey! It’s an opportunity to revisit breaks the pause idea for Spark. I still don’t know how I want to handle that, but I have the next 9 days of vacation to figure that out. 😆
A fragment of the iOS habit tracker app, Spark, showing the "Habits" section. The screenshot displays two habit categories under "Side Hustle": "Work on side project" with a 125-day streak and "BuildInPublic" (hashtagged as #BuildInPublic) with a 171-day streak. Each habit includes a weekly progress tracker for the last 7 days, with today marked as Monday. The "Work on side project" habit is visually represented with green circles, while the "#BuildInPublic" habit uses blue circles. Both habits show consistent completion over the past week excluding last day.

There is nothing better than a feeling when you finish a big refactor, remove a few hundred lines of code, and the app still works the same or maybe even better (I fixed a few bugs alongside refactoring the code). 😅

New features require a new data schema, and that means a lot of code… 😮‍💨 I spent a few hours with Xcode and the results are… very subtle, for now. 😅 Can you even see them here? 😆
#BuildInPublic #IndieHacker #iOSDev #IndieDev
Two smartphone screens displaying the detail views of the "Write a Journal" habit in the Spark app. The left screen shows the updated design where the label has been changed from "Brief" to "Reason," and the calendar now reflects not only the current streak but also the full history of completed days. The right screen displays the previous design with the "Brief" label and a calendar that primarily highlighted the current streak. Both screens show monthly progress for May, June, July, and August.

I took a few minutes here and there yesterday evening and some time after work today, and I managed to set an intents flow, so I can now schedule timers from live activity! 🥳 It’s a small success, but after a tough day at work, it’s more than enough to put a smile on my face. 😅

Well, it seems I won’t have an #MVP this weekend, as I forgot I made some plans for today’s afternoon. 🤦 However, it’s not that I did nothing. I integrated #AlarmKit and even created a live activity! 🥳

I thought I’d do much more today, but it’s nice weather out here, so it’d be a sin to spend the whole day in front of the screen. 😅 You can see some fruits of my work in the video. ☺️

I used the little time I had today to clean up the code and finish the onboarding flow. I decided to add a shadow between buttons on the bottom and the view to match the new paywall. ☺️
#BuildInPublic #IndieHacker #iOSDev #IndieDev
Two smartphone screens displaying the final version of the onboarding flow for the iOS habit tracker app, Spark. The left screen shows a welcome message with a flame logo and three key points: building better habits one spark at a time, tracking progress to stay motivated, and using iCloud sync to keep habits close. There is a prominent red "Let's start" button at the bottom with a subtle shadow separating it from the background. The right screen is titled "Reminders" and explains that the app will send gentle reminders to help users stay on track with their habits. It includes an example notification and mentions follow-up reminders that can be disabled in settings. This screen also features a red "Enable notifications" button with a similar shadow effect, and an option to choose "Later."

I think I've finished the new onboarding flow. It's not perfect, especially the paywall, but it's better than what's right now. I didn't change much, but it's now more coherent with the app, and I like it much better. ☺️

I gave a try to a @revenuecat.com’s new paywall tool and… I have mixed feelings. It seems great and has a ton of possibilities, but it seems like I can’t achieve what I really want to. 🫠

A screenshot of a smartphone displaying a paywall for the Spark+ subscription within RevenueCat's paywall design tool. The paywall offers two subscription options: a yearly plan at $5.83 per month, billed annually at $69.99, and a monthly plan at $9.99 per month. The screen includes a flame logo, a list of features such as thousands of curated recipes, a vibrant private community, new recipe recommendations, and priority support. There is a red button labeled "Subscribe now!" and links to restore purchases, terms, and privacy policy. The screenshot is framed within a preview interface showing the language set to English (United States) and a zoom level of 0.6x.

Now, the main screen redesign. There are a few reasons I’m working on it. First is that I was somewhat broken on iOS 26, so I needed to fix that. For example, the header with the logo, I couldn’t make it look fine on 26, so I followed Apple’s UI guideline and used clear language.
Two smartphone screens displaying the current and new design of the Spark iOS habit tracker app. The left screen shows the current design with more shadows under elements, a logo, and less vibrant colors. The right screen displays the new design with less pronounced shadows, more coherent and vibrant colors, and the logo replaced with a "Habits" label. Both screens feature habit tracking categories such as Morning Exercise, Drink Water, Meditation, and Write a Journal, each with progress indicators and weekly tracking.

The only quite good screen from onboarding, I’m kinda proud of, is the one asking for notification permission. But it’s only because of the mockup of notification I created in there. It still stands out when it comes to the overall UI of the app.
A smartphone screen displaying the second screen from the onboarding flow of the Spark iOS habit tracker app. The screen is titled "Reminders" and explains that the app will send gentle reminders to help users stay on track with their selected habits. An example notification is shown with the text "Go for a run. Stay on track! Have you logged your progress today?" The screen also mentions that users will receive follow-up reminders if they miss an entry, which can be disabled in the settings. There is a red button labeled "Enable notifications" and an option to choose "Later."

First, let’s tackle the elephant in the room - the onboarding and paywall. They don’t look bad, but they definitely don’t look good either, and I don’t feel they belong to the app as the design is completely different.
Three smartphone screens displaying different views of the Spark iOS habit tracker app. The left screen shows the welcome screen in the onboarding flow with a flame logo and a "Let's start" button. The middle screen displays the paywall for Spark+ subscription, offering a 12-month plan at $19.99 per year and a 1-month plan at $1.99 per month, both with free trial options. The right screen shows the current design of the main view of the Spark app, featuring various habit tracking categories such as Morning Exercise, Drink Water, Meditation, and Write a Journal, each with progress indicators and weekly tracking.

Before that I decided to tackle the paywall, as it may not look bad, but I don’t think it matches the app. I use @revenuecat.com, so I can leverage its dynamic paywalls, but… I just don’t feel like I have full control then. 🫤
A smartphone screen displaying a paywall for the Spark+ subscription in the Spark iOS habit tracker app. The paywall offers two subscription options: a 12-month plan at $19.99 per year ($1.67 per month) after a 1-week free trial, and a 1-month plan at $1.99 per month after a 3-day free trial. The screen includes a flame logo at the top, a list of features such as tracking unlimited habits, customizing habit colors, and staying on top of goals. There is a red button prompting users to start their 1-week free trial. Links to restore purchases, terms and conditions, and the privacy policy are provided at the bottom.

Today I’ve been working on refreshing the onboarding experience and I’ve already finished the welcome screen. 😊 I’m thinking about adding the creation of the first habit to the flow.

Two smartphone screens displaying the welcome view of an iOS habit tracker app called Spark. The left screen shows the current design with a flame logo image, smaller icons, and text elements that are not aligned. The right screen shows the redesigned version with a flame symbol instead of the logo image, larger and colorful icons, and aligned text elements.

One thing that surprised me - Apple changed how purple looks! 😱 If I’m being honest, I don’t like it. I much rather liked the previous version, but I’m thinking about reworking the available colors, so I might just create proper purple myself anyway. 😂
#IndieHacker #IndieDev
Three iPhone mockups showing the detailed view of the “Write a Journal” habit across different UI versions. Each phone displays a dark interface with purple gradient backgrounds. The screens show “Write a Journal” as the title with “59 days” streak and “3 days” goal indicators. Below is a brief description: “Reflect on your day by writing a journal entry before bed.” The main content area features a calendar grid view showing four months (April, May, June, July) with circular dots indicating completion status - purple dots for completed days and gray dots for incomplete days. The layout demonstrates consistent completion patterns across the months. A “More” button appears in the top right, and navigation elements are visible at the bottom. The progression from left to right shows subtle design refinements while maintaining the same core functionality and data visualization approach.

I think I finished the UI refresh. It’s not much, just small changes here and there, and the app looks differently. Hope you like it. ☺️ I also run it on iOS 26, and it looks like I don’t have to change much for it to look acceptable. 😅 What do you think?
#BuildInPublic #iOSDev
Three iPhone mockups displaying the evolution of Spark habit tracking app’s main interface. The leftmost phone shows the current UI with a sight gradient background from white to red. The screen displays “Spark+” branding and four habits: Morning Exercise (pink, 1 day streak, 2 days goal), Drink Water (orange, 1 day streak, 1 day goal), Meditation (green, 1 day streak, 1 day goal), and Write a Journal (red, 59 days streak, 3 days goal). Each habit shows a row of circular day indicators (S S M T W T F) with completed days highlighted in the habit’s color. The middle phone shows a refreshed UI with “Habits” as the title and refined visual elements, maintaining the same habit structure but with cleaner typography and spacing. The rightmost phone displays the iOS 26 Beta version with further design refinements, featuring more polished gradients and updated interface elements while preserving the core functionality and layout.

What I could actually do when Xcode worked was to see that my custom headers with group names look strange on iOS 26, so I think I’ll move them from being coupled with cards and make them standalone all the time.
Two iPhone screenshots of the Spark habit tracker app side by side against a colorful gradient. Both show dark-themed interfaces with “Habits” headers and 09:41 time stamps. Left Screenshot (Updated): Features elevated category headers more separated from habit lists. “HEALTH” header appears prominently spaced above habit cards, demonstrating the design change where group headers are decoupled from habits. Shows “Morning Exercise” (pink theme) and “Drink Water” (yellow theme) with weekly progress circles. Also visible “MINDFULNESS” and “OTHERS” sections, including “Read a Book” habit (purple theme). Right Screenshot (Previous): Category headers positioned closer to habit lists. Same habits visible plus Both screens feature circular daily progress indicators (F-T) with completed days highlighted in each habit’s color. Bottom navigation shows “Habits” and “Settings” tabs, with “Habits” being selected.

I really tried, but #Xcode 26 is unusable right now. Not only does it crash every 5 minutes, I can’t make it open files in separate tabs when I click them. 😩 I just wanted to finish a slight UI refresh, making it ready for iOS 26. 😔
#BuildInPublic #IndieHacker #iOSDev #IndieDev
A macOS system dialog box with a dark gray background displaying an error message. At the top is a yellow warning triangle icon with an exclamation mark. The main heading reads “Xcode quit unexpectedly.” Below that is explanatory text stating “Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple.” Three action buttons are arranged vertically: - A blue “Reopen” button at the top - A gray “Report…” button in the middle - A gray “Ignore” button at the bottom In the top-right corner of the dialog is a small circular question mark icon, likely for help or additional information. The dialog appears to be the standard macOS crash report interface that appears when an application terminates unexpectedly.
