Bluestodon - Thread splitter
iOS Universel / Réseaux sociaux
Bluestodon is a posting utility for Bluesky and Mastodon.
It is not a timeline reader or social client - it has no feed, browsing, following, or notifications.
Instead, Bluestodon helps you compose longer posts, split them into threads automatically, preview how they will look on each platform, and post to both services at once.
# Write once, post everywhere
Type once in a single composer and post to Bluesky, Mastodon, or both at the same time.
Bluestodon automatically handles the different platform limits and thread structure for you.
# Automatic thread splitting
Long posts are split into clean threads independently for each platform.
Bluesky and Mastodon use different character limits, so Bluestodon adapts automatically and shows the resulting thread live before posting.
Force manual splits anywhere with `---`.
# Live dual preview
Preview the final thread side by side:
• Bluesky preview
• Mastodon preview
• Character usage gauges
• Post counts
• Media preview cards
See the exact output before sending.

Quoi de neuf dans la dernière version ?
Hashtag presets now sync across your devices alongside your accounts (when iCloud sync is enabled in Settings).
The alt text editor no longer jumps the cursor to the end of the field while you type. And when you reply to someone else's post with reply or quote controls set, those controls now apply to your own post instead of the post you replied to.
Plus a small app icon refinement.
