Photos for your closest 150.
A private photo app for the people you actually know, up to 150 of them, each connection mutual. No ads, no algorithm, and a feed that ends when you're caught up.
You're on the list.
We'll email you once, when One Fifty is on the App Store and Google Play.
How it works
One Fifty does three things. It connects you with people you know, shares your photos with them, and shows you theirs.
-
Ask to connect
Find someone by their exact username and ask to connect. When they say yes, you're in each other's circle. Nobody sees your posts unless you've both said yes.
-
Share a photo and a few words
Post a photo with a caption. It goes to your circle and nowhere else. There's no public profile, and no way for strangers to find it.
Catch up, oldest first. Then it ends.
Your feed shows what your circle has shared since you last looked, in the order they shared it. Nothing is ranked and nothing is promoted. When you've seen it all, the feed says so and stops.
Earlier posts stay on each person's profile.
The example feed shows three new posts, oldest first: Ravi Menon at Kovalam yesterday, Ananya Rao in Munnar this morning, and Meera Iyer's monsoon two hours ago. Then it reads: You're all caught up.
No ads. No algorithm. No strangers.
Members pay for One Fifty, so there's nothing to sell to advertisers. Posts arrive in the order they were shared. And everyone in your circle chose to be there.
No public profiles
Nothing of yours is on the open web. Someone who knows your exact username sees your name and can ask to connect, and that's all.
No counts
No follower numbers and no likes. Hearts are private: only the person who posted sees who sent one.
No endless feed
When you're caught up, the feed ends, and you can put your phone down.
Why 150
The anthropologist Robin Dunbar proposed that people can keep up about 150 meaningful relationships at a time. Later studies found them in layers that widen as closeness falls, often summarised as 5, 15, 50 and 150.
One Fifty makes room for that whole circle, and stops there. A place in it means something because there are only 150.
- 5
The people you turn to first, in a crisis or with good news.
- 15
The ones you'd miss most. You probably hear from them every month.
- 50
The people you'd invite to a big celebration.
- 150
Everyone you know personally. You'd stop and talk if you met them by chance.
These are averages, and people vary. Source: MacCarron, Kaski and Dunbar, “Calling Dunbar's Numbers”, Social Networks, 2016.
When your circle is full
Your circle has 150 places. Each person you're connected with takes one, and so does each request you've sent, for up to 14 days. When all 150 are taken, connecting with someone new means removing someone first.
It's a small decision, made rarely, and it keeps every place meaningful.

Private by design
Only the people in your circle see what you share, and the app is built to keep it that way.
-
Only your circle
Your posts, comments and hearts are seen only by the people you're connected with.
-
Private hearts
Only the person who posted sees who sent a heart. There are no counts to compare.
-
Screenshots blocked
The app blocks screenshots and screen recordings of what your circle shares.
-
No public photo links
Each photo loads through a private link that expires within the hour, so your photos aren't on the open web.
-
Report and block
Block anyone, any time, and report anything that breaks the rules. We look at every report within 24 hours, and the most serious are hidden straight away while we do.
-
Leave whenever you like
Deleting your account removes your posts, photos, comments and connections.
One Fifty is for adults: you must be 18 or over to join.

New parents
Share the early months with the people who'll want to see every photo.
Why we're building One Fifty
Photo apps were meant to keep us close to the people we care about. Over the years they filled up with strangers, ads and feeds built never to end, and the people who matter got lost in the crowd.
One Fifty puts sharing back at a human scale: the people you actually know, their everyday photos, in the order they shared them. Members pay for it, so there's nothing to sell and no reason to keep you scrolling. When you're caught up, it says so, and you can put your phone down.

Questions
When does One Fifty launch?
We're aiming for early 2027, on iPhone and Android. Join the waitlist and we'll email you once, when it's out. We'll say which countries come first nearer the time.
Is there a web version?
No. One Fifty is an app for iPhone and Android, so your circle's photos stay in the app. This website is only here to tell you about it.
Why 150, and do I have to fill it?
150 is about how many meaningful relationships people keep up at a time, on average. It's a limit, not a target: most circles will be smaller, and that's fine.
What happens when my circle is full?
To connect with someone new, you remove someone first. A request you've sent holds a place for up to 14 days, until it's accepted or you cancel it.
Who can see what I post?
Only the people in your circle. There are no public profiles: someone who knows your exact username sees your name and can ask to connect, and nothing else.
Can people take screenshots?
The app blocks screenshots and screen recordings. It can't stop someone photographing a screen with another camera, so share with people you trust. That's what your circle is for.
Are there ads? What happens to my data?
There are no ads, and we don't sell data. Members pay for One Fifty, and we keep only what the app needs to work. The full privacy policy will be published before launch.
How much does it cost?
Your first month is free, then $3 a month. Prices may vary by country and store, and you can cancel any time in your App Store or Google Play settings.
What happens if I delete my account?
Your posts, photos, comments and connections are deleted. We keep a minimal record of the sign-up for 180 days, for safety and legal reasons, and then delete that too.
Who can join?
Anyone aged 18 or over, with an Apple or Google account to sign in.
