Katapult — Community App Review
Version: 1.1
A simple launcher for the Mudita Kompakt, similar to the default launcher but with notification indicators, app re-ordering, and customizable home screen shortcuts.

Thanks so much! my favorite launcher, although I haven’t tried your InkOS, Katapult seems more akin to the stock launcher which I like.

@adizzy Thank you so much for the comment and the coffee 
You’re right this launcher was built specifically because a part of the community likes the stock launcher they just were asking for some customizations.

What a great launcher! You’re a man full of pleasant surprises. 
The launcher is nearly perfect in my eyes, but given there have only been two versions thus far, I have noticed a couple of bugs. I have some feature/design wishes too. I’m not entirely sure where to post them, so I’ll dump them here if that’s okay.
Bugs:
- The Katapult home menu (containing settings, hidden apps, etc, and their respective menus) should close when the home button is pressed or if the empty area outside it is touched. At the time being, it can only be closed using the back button. I often find myself pressing home to no avail.
- This might be a bug in Mudita K OS, but just in case it’s related to Katapult: in the stock SMS app, if I press the “+”-button and proceed to write the name of a contact or a phone number, the button which appears saying “Send to: [contact or number]” does not forward me to a chat page. If I have written a number and press the button, the area where I would input text and the keyboard both flash briefly, and the text that I inputted is immediately cleared. The same thing happens if i input the name of a contact and click their name.. I am in neither case forwarded to the page where I can send them a message. The only workaround is to create a group containing only the recipient and myself. If I want to send an SMS to a number, I have to first create a contact with that number, then add them to a “group”.
Wishlist:
- I would love an option to have the clock on the home page be identical to the clock on the stock K OS lock screen (i.e the screen featuring the bottom text saying “touch the power button to unlock”). I’m thinking in terms of size; placement; font; date/day formatting (“Friday, 01 May” vs “May 1, 2026”) ; 24hr formatting (e.g. "9:00” vs “09:00”); am/pm placement (and font); etc. Visually speaking, unlocking the device would in this scenario only affect the bottom half of the screen, unveiling the dock row(s) and media player if it is turned on. If the status bar is visible, it would also be nice if its little clock could be removed so that it would only show network/wifi to the left and the battery to the right. The status bar clock should be visible in the app pages, though.
- Placement-wise, this would have to take into account whether the status bar is enabled.
- It would perhaps be nice to be able to swipe left [= finger moving to the right???] back into the home page from the first app page, and vice versa. But it’s also fine as it is.
- I would like the option to remove the arrows in the bottom of the app page, but to keep the page indicator dots as well as the slightly compressed, above-center placement of the apps. Optionally, the arrows could be inside bubbles instead of rounded squares, while keeping the apps as rounded squares.
- With InkOS, I really appreciated having the option to add "system apps/features” such as notification log, but I have found no way to access them with Katapult. Since there is no notification page or simple tray in this launcher, I hoped that I could check my notifications by adding that app/feature to the home or app page, but this was not possible. I would love to be able to add notification log or a similar system app which could gather and display notifications as a badge on the app icon.
- Alternatively—although you’ve said that you’re not going to add it, so feel free to disregard this wish—a notification page in a simple list format would be super helpful, perhaps accessible by swiping left on the home page (and also allowing to return to home by swiping right, or pressing home or back). The notification page could be the stock notification log or notification history app/feature.
- Alternatively, the home page could feature an optional bell icon with a notification counter (similar to InkOS) over or underneath the clock. Pressing it could take the user to the notification log or notification history app/feature… or in my wildest dreams: a list-formatted notification page native to Katapult.
- Alternatively—although you’ve said that you’re not going to add it, so feel free to disregard this wish—a notification page in a simple list format would be super helpful, perhaps accessible by swiping left on the home page (and also allowing to return to home by swiping right, or pressing home or back). The notification page could be the stock notification log or notification history app/feature.
- Now come to think of it, swiping left on the home screen to open a specific app is a nice feature overall. With InkOS, I used it to open the camera. Then again, lacking this option is also fine—it’s even somewhat nice in its simplicity.
- As a last thing, I wish that the stock K OS app icons were available in the “Change icon” menu.
Again, you’ve done some fantastic work, gezimos. I wish I could help with the development in a more hands-on way, but I simply don’t know how. I am however fairly good at writing long lists, in case that’s helpful.

Your notification issues will be fixed with downloading KompaktX. I actually think it does notification view and access better while providing must-haves (for me) to make the Kompakt experience better. I see what you’re saying about the date, and I agree. Although as an American, I like the current date and time format that Katapult offers. I really hope Mudita does the exact same format for their lock screen.

Thanks so much for the kind words and the feedback
Bugs:
- This was done on purpose, it’s not a bug. I like to experiment with UX in some cases it might be counter-intuitive.
- Indeed this is not related to the Launcher
Wishes:
- There’s Notification log and app notification shortcuts in Katapult settings. Swipe to 2nd page. But there will be no notifications page added like inkOS.
- The icons that are on presets are icons that I created myself, I can’t include Mudita icons in my app, I don’t have permission to do that. I’ll see if i can redraw similar ones myself and include them but I can’t promise anything.
- Time/date comes from the system automatically depending on android/language settings, but I’ll see to add a format switch.
For the rest: All good ideas, however out of the scope of the app at least for the moment. The idea was to just fix the fundamental shortcomings of the default launcher, not make it super customizable.

@lightsaber Great advice, anyone looking for advanced notifications like in inkOS could pair Katapult with KompaktX.
@jmudita Glad you like it
@Henrik_J Thank you

I have a few sideloaded apps on my MK that I find necessary, and I really disliked how the stock launcher made the icons look. I switched to InkOS for a while, and that functionally was just fine, but I did feel a little like I was missing out on the aesthetic experience of the MK.
Katapult has solved all the issues I had and more. Nearly all my sideloaded app icons look great now, and those that don’t quite fit are easily spruced up with the custom icons. Thank you for refining the experience of this phone so neatly.

@TechVampire I’m very happy you’re liking Katapult
You can share the custom icons in the Katapult topic in the main forum for users that might use those apps in case they’re popular ones. And if any popular apps is not looking good let me know, I’ll try to add them to the app in the upcoming update.
Thanks for the kind words and sorry for the late reply

Katapult v1.2
Added
• Clock Format setting — cycle the home clock between System, 20:24 (24-hour), 08:24 PM, 8:24 PM, and 8:24. Replaces the old Show AM/PM toggle; the AM/PM suffix now appears automatically for the 12-hour formats that include it.
• Date Format setting — cycle the home date between System (locale long date), Mon, Jun 8 / Monday, June 8 / June 8, 2026 / 6/8/2026 / 2026-06-08.
• Disable Music Widget setting — hides the home-screen music widget.
• Bundled icons for Discord and Libro.fm.
Fixed
• The Home button now dismisses any open bottom sheet window — previously only Back closed them.

OMG Gezimos! Just now that I wanted to give up my Kompakt, you make this. Super.
Those round icons ‘feel’ so nice, too. It’s also nice that the audio player widget works with the stock Mudita Music app.
Compared to inkOS, I miss a button or icon to go to the Android battery saving settings so I can whitelist the third-party apps playing background audio.
Categories would be nice, too, so I don’t have an endless list of apps. Took me also way too long to figure out how to move app icons (hint for others: you ‘swap’ them)

Glad to hear so
I could maybe add a shortcut in the settings, because Katapult doesn’t support shortcuts and it would cause too much work to add them as “apps”.
IDK about categories for the moment. If you can give an example how you’re thinking I’ll add it to notes if I am able to do but I can’t promise.
The reason the re-ordering was done with swap is to eliminate ghosting on the screen from dragging icons around.

A shortcut in the settings is even better, just like you did for the notifications. I found that the shortcut like in inkOS was not the best solution, indeed. It took up space and it’s not really an app.
Not sure how it would look like without complicating it too much. The problem is that I have frequently used apps (more than the 5 on the homescreen) that I would like to access more easily without searching for them on one of the 4 pages I have now. I could in theory ‘hide’ the less frequently used apps, but that doesn’t feel proper. For me, the hiding is for apps that I really never or rarely use but don’t want to uninstall. Like the meditation app. Maybe I should just put frequently used app on the first page, but then the apps are no longer alphabetic, which feels less clean.
The swap makes sense, but you should add a small info about how to do it. I really assumed I had to drag. Maybe I missed it.

in inkOS I have removed them, users can simply search for them in Appdrawer (if enabled in App drawer settings) or if they manually add them with apps like Activity Launcher. So i’ll most likely just add a shortcut in the settings like Notificatons.
- Home for important apps
- First page of all apps (important apps)
- All less used apps on the 2nd page and 3rd if it exists.
- Rarely or never used apps in Hidden apps.
I think I mentioned that on the forum post. But you’re right I have to make it more obvious.

Hi,
Do I need to uninstall inkOS before installing Katapult? and is there any documentation please?
Thanks!

No need to uninstall inkOS before you install Katapult.
Read the original forum post or the website https://katapult.gez.im/ it’s pretty straightforward.
Not that I care about the rating of my free-open source apps, but just a genuine question:
Why rate an app you haven’t tried yet as 4 stars?

When I went to send my comment the forum system asked me for a rating before it let me hit send, so I chose 4 as it’s a great idea but I haven’t used it yet. No offence intended
