Had a password issue after latest IOS update and the App Developer resolved it promptly. Good customer service. Would recommend. ### 2/5 — Doesn't work with IOS 9 *2015-09-17* Since I installed IOS 9, this app isn't working anymore. They need to update it **Developer response:** Hi, Shagster27! It is up to date now, finally! ### 4/5 — It does what it promises *2014-09-14* But it could have a facelift, all the looks are quite outdated and it havent had an update in ages. I use it a lot and it's very helpful. A concern I have about this kind of apps, not this one in particular, is about trust. How do we know that it is safe and that we are not giving away our passwords to somebody? **Developer response:** Hi, Tucano.uy. We've finally updated the look of Cerberus! And about this trust issue, we don't save your password anywhere, not even on your device! That is a security procedure. ### 1/5 — Not really good *2014-05-16* Unfortunately this is not a very good app, and the developer does not take the "customer service" seriously. I just deleted from my phone. If anyone knows another app similar to this one let me know. But please, not the same Developer!! ### 5/5 — Watch the dog!!! *2012-09-25, version 1.1* I quite like this program, seems to work well. The only thing to remember is DON'T forget your password, it's non recoverable. ### 5/5 — Awesome *2012-06-11* This app is great for all of you if your that forgetful type of person who needs to remember passwords! ## Frequently asked questions about Cerberus ### What kind of data can I store in Cerberus?
