  1. [R1] Cluster 2/5 · US Love it but slow: I love this app but pictures load very slow or don’t finish loading
  2. [R2] Cluster 5/5 · US Great app: So much sharing can be done
  3. [R4] Cluster 1/5 · US Photos: It will not let me upload any photos
  4. [R5] Cluster 5/5 · US Photo Books are Great: Just like the other reviewers, I too am very impressed with the Cluster App. Very easy to use and to interact with the current 25 users in our group. What these reviews don’t mention is the ability to create photo books. I have created 2,12x12 and 1, 8x8 hardbound books as well as 4, 5x5 soft cover books. The quality of the prints is fantastic. And the is no difference in
  5. [R9] Cluster 3/5 · US Logging in issues: I cannot view my groups and I logged out to attempt to fix it but now I can’t log back in. Please advise on what to do to or if anyone else is experiencing issues as well.
  6. [R11] Cluster 4/5 · US LOVE this app but needs category system: Loving the concept to share photos away from social media! However, with the amount of photos my family uploads, many photos are getting lost. Having categories or folders would be helpful to find photos for specific events instead of scrolling through thousands of photos.
  7. [R15] Cluster 3/5 · US Glitchy: This app has constant glitches. Some days I can’t post at all. Now it’s not notifying people when I do post even though they were getting notifications before. Sending invites is a pain - sometimes people get them sometimes they don’t. Sometimes the link works, other times it doesn’t open anything. Also only some android users can use it. Some with newer androids tell me they can’t get th
  8. [R6] Cluster 3/5 · US Help I have a Android: My husband and my brother, both have androids and when they try to download your app, it says the software is updated for Android phones.
  9. [R7] Cluster 1/5 · US Photos don’t upload: Couldn’t get the app to work, kept freezing, had to reinstall, the photos wouldn’t upload very frustrating waste of time
  10. [R16] Cluster 1/5 · US Needs Update: App constantly freezes. I can't view or upload any photos. Please update!
  11. [R3] Cluster 3/5 · US Works for what I use it for: I take the photos for our towns youth football league. 4 age divisions and I can have a cluster group for each division. I wish I could have a QR code for each group, it would make sign ups for parents SO much easier! The link is ok but not as efficient, I would even go premium if that was an option because I use this app weekly from July-November for hundreds of kids
  12. [R47] Cluster 4/5 · US Very Useful!: For years, Cluster has been a family link: for people and activities, for our homestead, for cooking/eating adventures, and even pix from our budding six-year-old photographic granddaughter. Much fun for all! I imagine that the same can be done on Facebook or other social, but on Cluster there are NO ads, and I have NO SENSE of our ID being sold. There's NO pushing of anything. Yes,
  13. [R53] Cluster 5/5 · US Treasure: My son Levi passed in 2019. Cluster has been a huge part of my coping as I pass through this life without him. Having his pictures in one place is a treasure. I’ve tried to become a paying member of Cluster but have not found out how to join. I want to be a supporter of Cluster just how Cluster has supported me. Thank you
  14. [R60] Cluster 1/5 · US Too buggy: Now cluster wants us to pay a subscription? Well, I’d be happy to if the uploads didn’t frequently fail. Fix the bugs so the app works and then ask us to pay.
  15. [R19] Cluster 1/5 · US Fix this outdated app: The app has not been meaningfully updated in years. My first nephew was born in 2016 and this app is still the exact same with terrible UI 9 years later for when I’m having my first kid. Now I’m forced to use this relic of an application bc my family already has it downloaded and all grand babies are on it. If I have to use it then please make it modern and with more functio
  16. [R24] Cluster 3/5 · US Is Cluster still supported?: This app was great years ago, I suspect there's just zero support judging by all the reviews complaining about it. Unfortunately, that's what I came here to confirm. I can barely use the app without it crashing. If i try to save a photo to my iPhone it crashes immediately, and it's been doing that for years. I just take a screenshot then crop it. I was happy to sup
  17. [R33] Cluster 3/5 · US Not getting notifications of posts: We have used Cluster for about 3 years and have loved the ability to share pics privately. Starting in early December notifications of postings have not been received by members of the group. I know of one other user of Cluster who is having the same problem. I have requested help from the site 3 times and have had no response.
  18. [R64] Clusterduck 1/5 · US still getting ads: paid for no ads. still getting ads…
  19. [R23] Cluster 4/5 · US Great FB alternative: Between family issues, moving, and a LOT of loving church members, babysitters, and relatives, this app has been AMAZING for posting updates on our niece. As legal guardians, we wanted to keep her pictures private and separate from social media, give everyone simultaneous access to the same pictures/updates, allow them to add their own pics, and the notification system tells
  20. [R41] Cluster 5/5 · US 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 Mai
  21. [R70] Clusterduck 1/5 · US Paid $20 to remove ads, still getting full page pop up ads: Still getting a full screen ad when I open the app. But paid $20, apparently for nothing.
  22. [R106] Clusterduck 2/5 · GB Just broke and took my money: I had bought the no add banner on my separate account for Clusterduck. I know it would work as last time I did it, it worked flawlessly. But this time it just took my money and didn’t do anything. What’s worse is that the purchase broke the game not letting me close any adds now. It doesn’t have an undo-purchase button so I can’t do anything about it expect lose money
  23. [R10] Cluster 2/5 · US Stopped uploading: I love this app but it no longer allows me to upload anything. It just fails every time no matter what I do. Please fix it!
  24. [R73] Clusterduck 1/5 · US Cash grab: Unless you want to spend money your fun will end after about an hour!
  25. [R75] Clusterduck 3/5 · US Space: I think the game is great and very addicting, in a good way. I just wish that I could have more space that I could get with the in game money or just more starting space.
  26. [R87] Clusterduck 3/5 · GB money grabbing: bit of a mixed review. i love this game but why are we only allowed 25 ducks unless we pay REAL money and even then you only get 50 ducks. there’s a lot of features in this game hidden behind a paywall and it’s ruining a potentially good game. i’m sure y’all can add optional ads or something if you need money but asking £4.99 for a basic game feature is genuinely theft. ruining a g
  27. [R100] Clusterduck 1/5 · GB They trashed a perfectly good game: This game used to be excellent. Bought it on another device recently to discover they’ve got rid of the paid for options of time skipping and it’s become so money grabbing it’s almost impossible to get any satisfaction out of playing. Have moved to a less grabby game with similar mechanics that is just as charming. It’s just so disappointing to see the game die
