See all cloud storage files in one app, transfer files from one cloud to another on my iPhone. Boo hiss. First of all, you can only have one account per cloud so if you have more than one Dropbox account, forget it. Then the app says to register for a free rainbow account. Sure, registration is free but doing anything with it costs. Essentially you’re just giving them a free mailing list by registering. Disappointment. Delete and keep searching **Developer response:** Hello, What was the problem with connecting to a second (or third) Dropbox account? When you create your Free Rainbow account you can share files with total size of 500MB (without that account is only 100MB). We are sorry to see you leave, and we hope you return soon ### 5/5 — Great cloud manager *2019-02-21* I love the app easy to use once you know everything Is at easy file transferring between cloud services must have app if you have multiple cloud services Had a problem with Dropbox but thanks to the quick response and yes the update fixed the problem. I do wish I could hide the other cloud services that I dnt use and keep the ones that I use when I open the app **Developer response:** Hi, thank you for the rating. Currently you can change the order by dragging them. But, this is indeed a nice feature. Could you please sends an email so that we can further discuss this feature? Thank you ### 1/5 — How difficult is it to sync two folders? Very using this awful app! *2017-08-26, version 3.0.1* How difficult is it to sync two folders? Very using this awful app! Cannot make sense of the interface at all. ### 1/5 — Crash since last update *2017-08-13, version 3.0* Sync, backup and file transfer impossible since last update, crashes and has rendered the app unusable. Also signs out of all cloud services after crash. ### 5/5 — This app is exactly what I needed!! *2017-08-09* After trying others, there was no alternative to this app. There's no competition to this app due to the amount of features and abilities it enables its users to do. ### 2/5 — No PogoPlug as Shown in Description *2017-07-23* Was hoping that PogoPlug would be supported. The description shows PogoPlug but the current version of the app itself doesn't have it. I'll guess it's Apple again rendering useful Apps into useless Apps by not supporting earlier App versions. Too bad. **Developer response:** We are sorry for this, but this is not our decision. We used to support the Pogoplug service, but, then, the Pogoplug is no longer available ### 1/5 — Rainbow Cloud Transfer App *2016-10-26* The list of services no longer appears in the iOS app. Clicking on App Support takes you to the developer web site, but there is no obvious "contact us" link to report a problem. If one needs to subscribe in order to be able to transfer files, it is not obvious how to do so within the app. Good idea, but currently non-functional. I tried deleting it and downloading the latest version, but that did not help. **Developer response:** This issue is fixed in version 2.7.2 Thank you ### 1/5 — Crashes *2016-04-01* This app used to be good on older iOS, but running 9.3 now and it crashes when trying to transfer or backup files or folders. Tried to contact them thru there website but every time I pushed the submit button I got an error message saying I forgot to type my question, then what I typed in the box clears and have to start over again to just repeat the same problem. Until they fix these problems the app is useless. **Developer response:** Since this comment is for a very old version of the app, could you please try the latest version? Thank you ### 1/5 — Horrible UI *2016-03-30, version 2.5* The UI is ugly and unintuitive. Even if the functionality were superb it's not pleasing to the eye. Please follow proper UI design. ### 1/5 — What is this?! *2015-05-22, version 2.3* Waste of my time, user interface really need to be updated. ## Frequently asked questions about Rainbow ### What does this app do?
