* Featured as “New and Noteworthy” by Apple * 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 explain...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 it...it'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!” The press LOVES Cluster: • Featured by the Apple App Store (“New and Noteworthy”), NYTimes, TechCrunch and many more!

Verdict
The clearest difference is in-app purchases: MITA Messenger at none against Cluster's 6. Cluster's advantage is ratings volume (22K vs 4). On price, rating, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Cluster sells 6 in-app purchases, starting at $4.99 per month. MITA Messenger asks for nothing beyond the download.
MITA Messenger holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Cluster has 22K ratings behind it against 4, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 8, 2026 and November 4, 2026 respectively.
