About

Scripture Clock

Features
Read full description

Turn your old iPhone or iPad into an elegant wall clock that tells the time with scriptures! The clock shows not just the current time, but also a scripture passage whose chapter and verse match the current hour and minute of the day. Since there are usually several scriptures that match the current time, the clock chooses a random scripture each minute. For example, at 3:16pm, the clock might show John 3.16 (or Genesis 3:16 or Ezekiel 3:16 or any of the dozens of verses located at a chapter 3, verse 16 in the scriptures). If you tap the screen, the app will display a different scripture matching the current time, if there is one. If there is a scripture that you especially love, tap the "heart" icon in the lower-left corner of the screen. This will increase the likelihood that it will show up again, when the right time of day comes again. Tap the "settings" icon in the lower-left corner of the screen to adjust the font and color scheme, select preferred works of scripture, and toggle 12/24 mode. Scriptures are selected at random from the Old Testament, the New Testament, the Quran, the Book of Mormon: Another Testament of Jesus Christ, the Doctrine & Covenants, or the Pearl of Great Price. Bible verses are taken from the King James version. Quran verses are taken from the English translation by Talal Itani. For the top of the hour (i.e. when the minute is :00) the clock shows a chapter heading. For example, at 6:00, the clock will show the heading for a randomly-selected chapter 6 from the scriptures. There are a few times during the day that have no corresponding chapter and verse (for example, 11:59). For those cases, the clock shows the current time plus a randomly-chosen inspirational quote. INSTRUCTIONS FOR USE: 1. Install the Scripture Clock app. 2. Launch the app and wait for it to start (this can take a few seconds). 3. Plug your device into a power source. 4. Set your device on a surface (or mount it to a wall). 5. Watch as your new Scripture Clock tells you the time, with a new verse of scripture each minute! 6. If you especially like a particular verse, tap the heart in the corner to increase its likelihood of showing up again.

Master Any Subject with Spaced Repetition Flashcards Stop wasting time reviewing what you already know. This app uses spaced repetition and the proven Leitner Box System to show you the right flashcards at the right timeβ€”so you learn faster and remember longer. How Spaced Repetition Works Traditional studying is inefficient. You review everything equally, whether you know it or not. Spaced repetition fixes this by scheduling reviews based on how well you remember each card. New or difficult cards appear frequently. Cards you know well appear less often. This targets your weak spots while reinforcing what you've learned. Research shows spaced repetition can improve long-term retention by up to 200% compared to massed practice. Medical students, language learners, and professionals worldwide use this technique to master large amounts of information efficiently. The Leitner Box System This app implements the classic Leitner Box System with 5 boxes: β€’ Box 1: Daily review β€’ Box 2: Every 2 days β€’ Box 3: Every 4 days β€’ Box 4: Weekly review β€’ Box 5: Every 2 weeks When you answer a card correctly, it advances to the next box and appears less frequently. Answer incorrectly, and it returns to Box 1 for immediate reinforcement. This simple system ensures optimal spacing without complex algorithms or manual scheduling. Create Powerful Flashcards Build your own decks with flexible card types: β€’ Text cards for vocabulary, definitions, and facts β€’ Multi-line text for longer explanations and formulas β€’ Image cards for diagrams, charts, and visual learning β€’ Drawing cards for sketches, equations, and annotations Mix and match content types on front and back. Create a card with an image question and text answer, or a text prompt with a hand-drawn diagram. The flexibility adapts to any subject. Study in Both Directions Sometimes you need to recall in reverse. Toggle the study direction to see the back of cards first and recall the front. Perfect for language learning where you need to translate both ways, or any subject where bidirectional recall strengthens understanding. Track Your Progress Monitor your learning with study session analytics. See how many cards you've reviewed, your accuracy rate, and which decks need attention. Watch cards progress through the Leitner boxes as you master the material. Organize Your Knowledge Create unlimited decks for different subjects, courses, or projects. Each deck tracks its own cards, due dates, and progress independently. Whether you're studying for one exam or managing ongoing professional development, keep everything organized. Built for Focused Learning No social features. No distractions. No gamification gimmicks. Just effective flashcard studying based on cognitive science. Open the app, review your due cards, and get on with your day. Offline and Private Your flashcards stay on your device. Study anywhere without an internet connection.
