It is a lightweight, privacy-first Fediverse client for iOS, built around a simple idea: fast, small, predictable behavior, and first-class support for snac.

What makes it different:

• snac-first by design, not "compatible by accident"
• Works with all Mastodon API compatible software, including Mastodon, snac, GoToSocial, Akkoma, and others
• EXIF stripping on upload (HDR and orientation preserved)
• Optional on-device alt text generation via Apple Intelligence for your uploads and for images in your timeline
• Markdown posting for snac
• Granular notifications, grouping, multi-account
• Blocking and moderation tools
• Very small footprint, very low RAM usage

Alt text generation happens entirely on device via Apple APIs on supported hardware. Nothing is sent to external services.

It is built around my own workflow and priorities. It may not be for everyone, and that is perfectly fine.

Important note:
MastoBlaster will always be free for BSD Cafe users, illumos Cafe users, and for anyone connecting to a snac instance, including self-hosted ones.

The app is already usable, but this is still a test phase. I am looking for feedback, bug reports, and real-world usage insights.

#MastoBlaster

This is a major release that merges several different development branches I've been working on, bringing together a lot of moving parts into a single build. A long, sleepless night…

Here is what changed:

• Full Drafts Support: A complete end-to-end draft flow. It includes auto-save, the ability to edit existing drafts, and a smart cancel confirmation that either discards a new draft or restores the original state if you were editing. It supports replies, quotes, polls, and media metadata.

• Trending Posts: Added a new trending timeline type with proper offset pagination support.

• Timeline Position Improvements: Added extra protection to stop SwiftUI from overwriting your saved scroll position when the view disappears or goes to the background. If a saved post can't be found in the cache, the app will now try a direct status fetch before giving up.

• UI & Navigation Fixes: Tapping Content Warnings (CW), "Show Filtered Post", or "Show More" now goes through an inline-action guard, fixing the bug where tapping them would accidentally trigger row navigation into the thread. Filtered posts also get proper bottom padding so the list separator doesn't sit on top of the button.

• Instance Compatibility & Tweaks: Added customizable timeout settings for slower instances (like snac on older hardware). I also fixed the 405 error when setting alt text on GoToSocial, and updated marker sync to strictly align with Mastodon’s documented form shape.

• Testing focus: I've implemented search fixes ensuring queries stay locked to the account you are searching from. If you are on GoToSocial, please test this thoroughly and let me know how it behaves. Since this build is the result of a massive merge, keep an eye out for any regressions.

MastoBlaster build 95 is out, and I am getting close to declaring it stable.

Here is exactly how it works now:

• Tap Home from another tab: Switches back to the Home tab.
• Tap Home while already there: Scrolls the current timeline to the newest posts.
• Tap Home again while already at the top: Refreshes the timeline (with a 1.5-second cooldown to prevent accidental spamming).
• Long-press Home: Opens the timeline picker.

• Added a setting to completely disable Apple Intelligence.
• Redesigned the notification view to be larger and make much better use of screen space.
• Fixed the compose window layout for small devices like the iPhone mini.
• Profile and banner images can now be tapped to enlarge.
• Added support to approve or deny follower requests.
• Added per-instance and per-account connection timeouts.
• Added a visible Back button to the settings sheet.
• Updated the filtered notice UI: it now shows "Filtered Post ()" directly in the header and removes the separate "Matched:" line.

#MastoBlaster #MastoBlasterUpdate #Fediverse #iOS #Apple

This update focuses primarily on fixing several layout issues reported in previous versions. The interface should now appear much more stable and consistent.

I especially encourage beta testers using an iPhone mini to check the visual rendering on smaller screens.

Please submit your feedback and report any bugs directly through the TestFlight app or by replying to this post.

Thank you for your support!

@mastoblaster Testing your app with my GTS servers. Is there an issue or bug tracker where issues can be documented?

• Added support for uploading audio/video files.
• General fixes.

Push Notifications and MastoBlaster

MastoBlaster, like other Fediverse apps, uses a design that maximizes user privacy.

When you log in to your instance, the app and the server exchange the necessary cryptographic keys. The app also communicates to the instance the address of the relay, which is the server responsible for forwarding notifications to Apple.

When a new notification is generated:

1. Your instance encrypts the notification.
2. It sends the encrypted payload to the relay.
3. The relay forwards it to Apple using its own authentication key.
4. Apple delivers it to your device.

The content of the notification is encrypted by your Fediverse server and can only be decrypted by your device.

The relay, which in the case of MastoBlaster is dedicated and hosted on a FreeBSD server, receives only encrypted data. It cannot read the content, does not know which account the notification belongs to, and does not store any information about the notification itself.

Apple knows which relay sent the notification and which device it must be delivered to, but it cannot access the content.

In short, only your instance and your device can read the notification.

• Build 77 should have fixed the markdown rendering issues
• Build 78 should have fixed the GoToSocial char limit issue

#MastoBlaster

The difference from other Mastodon API clients is that this one has #snac as a first class citizen.

I'm so glad!

Attention #GoToSocial people: I have been testing @mastoblaster - an iOS Fediverse client - and it's working SO WELL! It's even grouping GtS notifications... something that Ivory doesn't do.

Congratulations @stefano for your brilliant work on it!

#snac #MastoBlaster

This will be reworked after fixing some other bugs.

It should be fixed now.

Sorry about that

#MastoBlaster

A new build is now available on TestFlight. I tried to solve or improve some of the issues you've kindly pointed out.

The most important ones are:

• Now dark mode can be configured to show a grey background instead of black. Less optimised for battery, but much more readable. "It works for me!"
• Added the “Bookmarks” menu item, so bookmarks can now be displayed
• VoiceOver improvements - I'm not an expert, so I hope I'm doing it right
• GoToSocial - editing posts and push notifications should now be working - Notifications needed both relay and app support. Please test!

As for the pricing, I kept it free for the communities I manage (BSD Cafe and illumos Cafe) and snac instances because the people there and the creator of snac have given me a lot.
It’s simply my way of giving back.
Also, regarding EXIF: many apps don't strip it client-side (instances might, but depending on the implementation, it's not a given).

You clearly have strong opinions, but a piece of advice: you can disagree with a project without needlessly trashing others' work. You are always free to just scroll past. I've been contributing to the Fediverse and digital freedom for a very long time, and while I always welcome constructive feedback to improve, basic respect goes a long way.
