A fun and didactic app to learn computer science algorithms! See how algorithms are working by watching an animation of their execution. Understand how data is manipulated as it is animated through an intuitive representation of its contents. Always know which line is executed in the pseudo-code, what are the values of the variables. Need to quickly refresh your memory? Just use the app as a quick reference on the main characteristics of each algorithm! Main features: - Execute a single instruction, or undo the previous one - Run, or rewind the algorithm until you decide to pause the execution - Adjust the speed of the animation - Best and worst case input data for sorting algorithms - Change the input data: size (up to 500), maximum value or data distribution (random, sorted, many duplicates, etc.) - For data structures, choose the next function to execute, or let a scenario choose for you, so you can see how the data structure evolves. - Landscape or portrait orientation This version contains the following algorithms: Linear Data Structures: - Linked Lists, including a view on memory - Queue - Stack Sorting algorithms: - Bubble Sort - Cocktail Sort - Gnome Sort - Insertion Sort - Quick Sort - Selection Sort More algorithms and more features are on the way!

God's Word for every battle of the mind. Temptation rarely shows up with horns and a pitchfork. It sounds like a thought in your own mind—a fear that won't quiet, a craving that won't leave, a lie that feels personal. You know the pull. You want to fight back. But in the moment, it's hard to know what to say. You're not alone in that fight. And you don't have to win it in your own strength. A PATTERN THAT ALREADY WORKED After Jesus was baptized, He went into the desert. Satan came at Him with temptation after temptation. Jesus didn't debate. He didn't panic. He answered every attack the same way: "It is written." Three times. Three verses. The written Word was His defense—and He overcame. Written Proofs helps you do the same thing when the battle reaches your mind. YOUR SIMPLE PLAN When temptation speaks, you don't need a sermon. You need something written to speak back. Name the battle — Tap a struggle like fear, anger, lust, or pride—or describe what's weighing on you in your own words. Receive your Written Proof — Get Scripture matched to the fight you're in right now, with brief encouragement on how to use it. Answer with it — Read it. Speak it aloud. Let God's Word respond where the lie spoke. The lie speaks first. Truth speaks back. BUILT FOR THE MOMENT YOU NEED IT • Matched to your struggle — Browse common battles or search what's on your mind. Whatever you're facing, there's a verse for it. • Private and on-device — Your searches stay on your iPhone. Scripture matching runs locally. No account required. What you share isn't sent to the cloud for processing. • Real ESV Scripture — Suggested references load the exact English Standard Version text so you can read and speak God's Word with confidence. • History when you return — Revisit past Written Proofs when the same battle shows up again. You're never starting from zero. • Follow Jesus' pattern — Don't just admire a verse. Use it as your answer. WHAT CHANGES You don't have to scramble for the right words when temptation hits. You don't have to carry the fight alone. When the thought comes—when the fear rises, when the craving speaks, when the lie feels true—you have something written to say back. Just as Jesus did in the desert. DOWNLOAD WRITTEN PROOFS Name what you're struggling with. Receive Scripture for the fight you're in. Speak it back. It is written. Important: Written Proofs offers Scripture suggestions for personal reflection. It is not medical, mental health, pastoral, or professional advice. AI-selected references may be inaccurate—always read Scripture in context and verify references yourself. If you are in crisis, contact emergency services or a qualified professional immediately.
