SkyDeckFollower history, post performance and engagement for Bluesky — on your iPhone.
The gap
The history exists. Bluesky just never shows it to you.
Your profile shows a follower count and each post shows four numbers, all as they stand right now. Underneath, the AT Protocol knows more than that: it records when each person followed you, and your posts keep their counts. Nothing in the app puts that together.
SkyDeck reads it and puts it in order — so most of your account's story is there the first time you open it, not only from the day you installed it.
- Bluesky shows
A follower count. Likes, reposts, replies and quotes on each post.
- SkyDeck reads and orders
When each follower arrived, growth over months, every post ranked by how it did, and who actually engages with you.
- Only unfollows start now
Unfollowing deletes the follow record, so nothing you can query afterwards says it was ever there. SkyDeck spots them by comparing syncs — which is why that one list begins the day you install.
Followers
Growth you can actually read
The curve is built from when each person actually followed you, so it reaches back through your notification history rather than starting the day you install. Daily bars cover the last 7 and 30 days.
Every follower sits in that list with their profile and the date they arrived, so a spike is answerable: open the day and see who showed up.
Who left
The list Bluesky never shows you
Bluesky sends no notification when someone leaves, and an unfollow deletes the record that would prove it. SkyDeck catches them by comparing one sync to the next: a dated list with the profile, how long they stayed, and the average across everyone who has gone since you started.
Useful for reading the shape of a week, not for keeping score. Nothing is posted, and nobody is told.
Posts
Which posts did the work
Your best posts for this week, this month, this year, or all time, with likes, reposts, replies and quotes listed side by side. Your whole back catalogue, ranked — which is the one thing scrolling your own profile cannot do.
Underneath, the people who reply and repost you most often — usually not the accounts you would have guessed.
Also in the app
Home screen widgets
Profile stats, your posting activity and your top post — per account.
Siri and Shortcuts
Ask Siri for your follower count without opening the app.
Posting heatmap
Months of posting activity in one scrolling grid, so gaps and streaks show.
Emoji stats
Which emoji you actually reach for, and how often. Not useful. Quite fun.
Several accounts Pro
Switch between accounts, including any custom Personal Data Server.
Your data
It stays on your phone
Followers, posts and engagement history are stored locally on your device, not on a server of mine. SkyDeck only ever reads what is already public on the AT Protocol, and only for the account you signed in as.
Anonymous usage statistics — which screens get opened, and what breaks — go to European analytics services so I can fix things. The privacy page names them.
This website sets no cookies and stores nothing on your device at all — not even a theme preference; it simply follows your system setting. That is why there is no cookie banner here asking you to accept anything.
Signing in
Sign in with Bluesky over OAuth, or use an app password if you prefer that. Either way, your real password never reaches the app, and you can cut off access from your Bluesky settings whenever you like.
Custom Personal Data Servers work too, not just bsky.social.

Answers
Questions people actually ask
Why do I need an app for this at all?
Because Bluesky shows you numbers, not history. The data is there — the AT Protocol records when each person followed you, and every post keeps its counts — but nothing in the app assembles it into a trend. SkyDeck reads that history and puts it in order.
Can it show me who unfollowed me?
Yes, from your first sync onwards. Unfollows are the one thing that cannot be recovered retroactively: unfollowing deletes the follow record, and nothing you can query afterwards says it was ever there. So an unfollow is only detectable by comparing what SkyDeck saw last time with what it sees now.
Can you see post views or reach?
No, and neither can anyone else. The public AT Protocol API exposes no impression data. Any tool showing you "reach" for a Bluesky post is estimating it. SkyDeck reports the four numbers that actually exist: likes, reposts, replies and quotes.
Do I have to give SkyDeck my password?
No. Sign in with Bluesky over OAuth, or use an app password if you prefer. Either way your real password never reaches the app, and you can revoke access from your Bluesky settings at any time.
Does it work with a custom PDS?
Yes. Any Personal Data Server works, not just bsky.social.
Where is my data kept?
On your device. Followers, posts and engagement history are stored locally, not on a server of mine.
What do I get for free, and what needs Pro?
Your history is free and is never truncated — followers, unfollows, the heatmap and your top posts for the current week, month and year. Pro ($2.99 a month or $24.99 a year) opens up top posts for past periods, the full engagement leaderboard beyond the top 15, and more than one account.
How far back does it go?
Your posts go back to your first one. Followers, and who engages with you, come from your notification history, which SkyDeck backfills as far as Bluesky keeps it — so most of your account is there on day one, not just what happens next. Only unfollows start counting from your first sync.
Is there an Android version?
Not today — SkyDeck is a native iOS app. Nothing rules one out later.

The history begins when you install it, so the sooner it runs, the more there is to look back on.
