The SBSS Knowledgebase is used to store information for anytime retrieval. No information or records are stored on the internet and the application needs no internet access, unless sending the record to an email recipient or using the Import / Export features. It’s been designed in a way that the records, when viewed, looks like a news feed or Social Media feed. The application stores all data in the phones database, including images. Every image is shrunk to 313 * 200 pixels which means the application will slowly grow in size. The storage of 2,500 records, with images, would increase the storage to half a gigabyte of memory, about the same size as the installation files of Pages or Numbers. With the images being stored in the phones database, it means that no images taken with the camera will be available in the Photo Library, only from within the app. Basically, a secret store of data and images. It can be used by students to help with revision, engineers to create a fault catalogue, IT Managers, surveyors, software engineers, project managers, maintenance managers etc etc etc. You could just use the app as a detailed personal diary or baby diary. The possibilities are endless.

Simple Diary is a simple, easy-to-use free diary app where you can save photos along with your entries. Use it for daily journaling, baby milestones, travel memories, a record of your pet's growth, or a secret diary just for you. Clean, simple screens help you keep going, even if diaries never stuck before. No account registration. Download it and start writing. Your diary stays on your device, and the app works offline. [Features] ■ Add Photos to Entries (Up to 10 per Entry) Like a blog, insert images between paragraphs. Attach photos from your camera roll. ■ Secure Passcode Lock Protect your diary with a passcode. Supports Face ID and Touch ID for quick, secure access. ■ 22 Font Styles Change the look of your diary with 22 font styles, from cute to classic serif. (Some fonts are premium.) ■ Theme Colors and App Icons Choose from 19 theme colors, from cute to cool. You can also change the app icon. (Requires the latest iOS version.) ■ Data Export Export your diary as PDF, HTML, RTFD, or TXT files (premium service). Open them on a computer to reread your diary on a bigger screen, or print entries on paper. ■ Turn an Entry into an Image or PDF Save an entry as one image or a PDF to post to social media, send to family, or print. ■ Data Backup Back up your data to iCloud or your computer. RTFD export (premium service) lets you move your entries to your notes app or cloud storage. ■ iCloud Backup Back up your diary to iCloud and restore it on another device (premium service). It is a manual backup, not automatic sync: back up on your iPhone, then restore on your iPad. ■ Calendar and List Views Look back at your diary on a calendar or as a list. Tap a date to reread that day. ■ Tag Search Use the built-in search to find entries quickly. Write a tag such as "#travel" in the text, and searching for it brings up just those entries. ■ Font Settings Adjust text size, contrast, and line spacing. Great if you prefer larger text. ■ Reminders Set a reminder time and get a push notification, so you don't forget to write. ■ Multiple Entries Per Day Write one entry per day, or add several for memos, work records, or passing thoughts. Change an entry's date and time to write about past days. There is no limit on entry length. [Pricing] The core diary features are all free: entries, photos, passcode lock, search, and reminders. The free version shows ads. The premium service removes all ads and unlocks iCloud backup, data export, all theme colors, and all font styles. Premium is available as a monthly plan, a yearly plan, or a one-time purchase, all with the same features, and covers both your iPhone and iPad under the same Apple Account. [Your Data] Your diary is stored on your device and is not synced to the cloud automatically. To protect your data, use the premium iCloud backup or Apple's iPhone backup. There is no feature to publish your diary or share it with other users. To show someone an entry, turn it into an image and send it. A backup moves your data to a new iPhone. Data transfer to or from other operating systems is not supported. [Perfect For] ■ Students A secret diary for your day, your feelings, and your crushes. Writing out what you can't post online helps you feel lighter. ■ Parents Record your pregnancy and your baby's growth as a photo diary. Write several entries a day, and share special pages with family as images. ■ Anyone Who Wants to Keep a Record Travel journals, reading and movie notes, food diaries, dream journals, daily work logs, or your pet's growth. Simple Diary fits whatever you want to remember, one day at a time. [Help, Feedback] For help, go to "Help / FAQ" in the app settings. Still have questions?
