Cluster makes it possible to create private groups where you share moments through photos and videos with the people you care about. Create a group with family, a group of friends, coworkers, people from your home town, or anyone else!

Great for:
• New Moms! Share photos of a new baby with close friends and family without spamming everyone on other social networks
• College Students! Share memories with friends not appropriate for Facebook
• Families! Keep in touch even if you’re not in the same place.

Tons of people already trust Cluster. Here’s why:

• Private & secure: Only invited members of the group can see what you post.
• An app for everyone: Access Cluster through gorgeous mobile apps and the web.
• Relevant notifications: Know when people you invited post new things to the group.

How it works:

1. Create a group.
2. Add the people you care about.
3. Share photos, videos and notes together.

People LOVE Cluster:

• “The app is fantastic! Me and my sister were so happy to find it. We made a group of the whole family and its great. My big brother is living in Europe, my sister traveling for the next 4 months and the rest of the family lives in Chile. They upload pictures and we can see how and what they are doing. Its very simple to use (even our grandmother is in the group!).”

• “I downloaded 10 different photo sharing apps, not including your Cluster app. I needed an app that allowed the creation of multiple albums, other users could join from anywhere, was password protected and SIMPLE. I deleted every app except your Cluster app. All the other apps were either too difficult to someone 8 hours away, too complicated to set up and/or upload, they limited the number of albums a user can create, required Bluetooth or wifi to share, or required a social media account to set up. Your app served all the purposes that I need. It is great, fabulous, fun & simple! Keep up the good work!”

• “I really like the privacy of the app and the fact that only people invited or with the code can access our pictures.”

• “I want to thank you all for such a wonderful product - it really has brought us all even closer together. The constant banter, the photo streams, the comedy...all of's been awesome. So, as far as my feedback goes, I'd say this is an awesome program and we'll continue using it for as long as it's available!”

Love this app- quirk + needs better user communication

I have been using this app for 4 years and love it.

One weird quirk is that sometimes when I upload multiple pictures it uploads them then a few hours later when I open the app again it uploaded them for a second time. I just delete them so it’s not a big deal, just a quirk.

Mid May 2022 I got an email saying Cluster was shutting down and was devastated. Mid June a family member / fellow user got an email saying Cluster was saved (!!!!), which is amazing news but I didn’t get the same email (checked spam, all folders, searched, etc). I emailed support twice but haven’t heard back. Please make sure you keep all of your users informed!

Try to find another app

I have been using Cluster for a little over 2 years now to post photos of my daughter for family. It has more or less been a decent experience, though their app can be glitchy, especially when you’re creating photo books on mobile. I found that anytime I’d try to swipe up to review my books on iPhone that it would totally crash out of the book and I’d have to go back in and start over. I got over that aggravation and proceeded to finish my books. When I went to order them, you can only order a single book at a time, so you get hit with shipping for each individual book. A full 100 page book costs $80 plus $8 shipping. They’re only tiny 12x12 books and honestly, $80 is asking too much for the result. Unfortunately, several years and thousands of photos later, I was married to the site and wanted to get my books created so I emailed customer service (Marlene) about the shipping costs which she said she’d credit back after placing my order. Five emails and three months later and I still have received NOTHING back from them. Not to mention the title printing on one of the books was cut off and I asked about correcting that as well. The app is fine if you won’t ever have to pull anything out of it, such as creating books. God forbid you need customer service to assist because it is non-existent with Cluster. I would say go elsewhere and find a better app that has actual support.

Exactly What We Needed

My family used to use an app called Path where it was a closed community and all we saw was each other’s posts. That app was discontinued over 5 years ago and we’ve been looking for a solution since.

This app is EXACTLY what we’ve been looking for. We now have close to 30 family members - cousins, uncles, grandparents, in-laws - connecting across the US from Hawaii to Maine to Florida. The UI is perfectly simple for everyone from 16 to 81 to use.

Thank you so much for making this and having it ad-free and accessible. This is connecting our large family for the first time in years. Thank you!
