Kase exists because it should. There should be a database app that can go anywhere with you. It should be: • Simple — Using it should be easy and intuitive, • Flexible — Once familiar with the basics, you can design any database to track anything important to you, and • Relational — Inter-linked data is an order of magnitude more useful. Plus, you don't want to repeat yourself. Additionally, it should be: • Personal — You should not need to worry about who can peek into your data, and • Always Available — High-speed wireless network should *not* be a prerequisite for accessing your own data. Structured data at your fingertips. Something like that didn't exist, so I started creating Kase in 2014. Basic Concepts: • Your Kase contains Boxes. • Each Box stores Decks that can relate to each other. • A Deck collects similarly structured Cards. • And a Card is where you put data Entries. Features: • Pick, assign, and organize with Categories, Tags, and Marks. • Search by name, notes, full text, or keywords: Full-text indexing with Natural Language Processing. • Highlight any Box, Deck, Card, Entry, or Keyword. • Deck definitions support inheritance! • Field types include Text, Number (with Unit), Money (with Currency), Date/Time (with Time Zone), Choice, Boolean, Link, Picture, and Document. - complete with multi-level auto-conversion • Write in Markdown and see rich formatted text. • Box can be locked with a passcode, and unlocked with Face ID or Touch ID. • Formatters (Fx) to visualize data in different ways without altering the data one bit. e.g. Unit Converter, NameMapper, WordScrambler, ICU Transformers... • Side-by-Side: Compare Cards easily by displaying in columns. • On-device Text Recognitions (OCR) for multiple languages. • Import/Export in CSV, JSON, or KASE. • Complete Backup & Restore. • iPad Multitasking support: Split View, Slide Over, etc. • Very customizable UI with custom locales What Kase Can't Do: - Cloud sync is not done yet (stay tuned...) What Kase Can Do: > From Data to Wisdom > Data ▹ Information ▹ Knowledge ▹ Wisdom 1. Store Data — the objective truths. 2. Organize Information — to reflect circumstances and current condition. 3. Systematically retrieve Knowledge — utilized for decision-making. 4. And that hopefully enables you to grasp Wisdom, comprehend insights, and ultimately create value. There are databases that belong to the Big Guys. The rest of them should stay personal. By now, you should realize how valuable your data is. So why give it away? Kase keeps your data yours.

Verdict
The clearest difference is rating: Kase₄ CE at 5.0 against iDatabase's 4.4. Kase₄ CE also leads on monetization model (free with in-app purchases vs paid) and iOS requirement (15.0 vs 18.6). iDatabase's advantage is ratings volume (510 vs 6) and update cadence (fortnightly vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. iDatabase sells 3 in-app purchases, starting at $1.99 per month and Kase₄ CE sells 7 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.
Kase₄ CE holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: iDatabase has 510 ratings behind it against 6, so its average is the more settled of the two.
iDatabase ships an update fortnightly, Kase₄ CE every 2 months. The most recent releases landed on October 16, 2026 and October 9, 2026 respectively.
