Long Time User Since Original Codebook

Love this app. I used to use the original Codebook app when it first came out on the iPod touches years ago. I loved it. I redownloaded the old Codebook and then stumbled upon their new Codebook app. Apparently the old Codebook is no longer supported by Dropbox, and with my large amount of notes on the old app I decided to migrate them into the new Codebook version. I’m super interested in purchasing the full version, especially knowing it’s not only a password keeper app but also where I can keep my private notes and ideas. However, my greatest complaint is the lack of dates on the notes. I have so many notes that migrated over, however none have any dates as to when I first wrote them. Instead, all the notes are categorized by alphabetical order. I love they kept with the old simple note style, but I strongly prefer the old original Codebook version that categorized notes by date order. Unless I was still able to see the date recorded as to when I first created that note, this app could have been perfect and I would’ve been more than happy to dish out for the paid version.
It’s such a minor thing too, you would think they’d let you categorize your notes by date created.

Developer Response ,

Hi Simply Claire,

Thanks very much for your support of Codebook and for writing this review. There's a view within Codebook called the Journal view, and it closely mimics the old Codebook (Secure Notebook) interface. Within this view you can sort your notes by created or updated date. It's located under [More] > Journal. You can edit your tab bar order (at the bottom of the screen) to have the Journal view first, so when you first launch Codebook it will be displayed right away. To do this, tap the [More] tab bar icon, tap edit in the upper right hand corner, then drag the Journal into the first position (replacing Categories). We'd be happy to assist if you have any questions when attempting these steps. Please feel free to reach out to us at

Still a class act after many years

My wife and I were introduced to STRIP a number of years ago when we were still using Palm Pilots. Our data made it across onto the iphone platform without any problem, and the app continues to give us peace of mind that our data is secure--not just passwords, but all kinds of important stuff. I very recently had an occasion to test the customer service of Zetetic, the app's developer. My email elicited a very quick response that reflected a careful reading of my description of the problem and provided a clear set of instructions for solving it. They followed up a day or so later to see if my application of the instructions had been successful, Altogether a class act. Consistent use of this app makes it remarkably easy to keep our data safe. The only improvement I can think of would be a field type or types that would store photographs or pdf’s.

Most Secure Password Manager

If you spend some time researching online, you may reach the conclusion that this is the most secure password manager on the App Store. Other password manager apps may not be secure if someone gains access to your device. I switched from the most popular competition due to persistence of major bugs in earlier OS versions.

The Codebook interface may not seem as polished as some competitors but is still pretty intuitive and excels in versatility. The app opens quickly without animation which I count as a plus. The sync is manual and does not occur in background. This could be a drawback if you frequently switch between desktop and iOS. I use iOS 90% so has not been inconvenient for me.

There is a category system but I primarily use global search. I just made a category "all" and dumped all my entries there in case I need to do a manual scan if search fails.

It now supports optional Touch ID. While convenient, enabling Touch ID probably makes the app less secure. While I appreciate Touch ID for quick access to phone calls and contacts I would not use for a password app where you may have your most sensitive data. This would allow anyone with access to your finger while you are unconscious to gain control. Control of your brain is harder to access.
