US Cop is an independent, offline directory of a deliberately limited set of current nationwide federal law-enforcement contacts. This edition includes source-attributed contacts for the FBI, DEA, ATF, U.S. Marshals Service, and U.S. Postal Inspection Service. Each record shows its official source and verification date. Search works offline, and important values can be copied. Phone, Maps, Mail, and Safari open only after you choose and confirm an available action. The directory is intentionally conservative. It is not a complete directory of federal, state, local, tribal, or territorial agencies. Contact details can change after verification; confirm important information directly with the agency. US Cop is independent and unofficial. It is not affiliated with or endorsed by any government or law-enforcement agency. It is not for emergencies. In the United States, call 911. Privacy: no account or cross-app tracking. Version 4.2.1 sends first-party analytics events for installation, Apple Search Ads attribution, access checks (including diagnostic information about whether the App Store purchase record could be confirmed), and verified subscription purchases. They include device identifiers; device, app, and locale metadata; and purchase details such as transaction IDs, product, dates, and the App Store receipt. Our analytics server also stores the IP address and an approximate location based on it. See the privacy policy for details. Analytics problems never change your access to the directory. US Cop is free to download. Full access to the directory needs a US Cop Weekly subscription. If you bought US Cop before it became free, you keep full access without subscribing. US Cop Weekly: $4.99 per week in the U.S. (other storefronts show the local price). Payment is charged to your Apple Account when you confirm the purchase.

Crammer lets you create unlimited flashcards, decks and folders for every subject for free. It's the most efficient way to memorize your study material before quizzes and exams. It drastically improves your learning speed. It uses an advanced spaced repetition and smart active recall algorithm to ensure that you review flashcards right before you may forget them. After reviewing a flashcard, you tap it to reveal the answer on the back of the card. You swipe right if you easily remembered it, left if you forgot it, or down if it took some effort and would like to review again. Crammer's algorithm will show you harder cards first and more often to help you really optimize your memory and prevent you from forgetting your study materials. Practice it a few times before your quizzes and exams to remember the study material. Here's how to use Crammer in your studies: - Create flashcards by either manually typing the Front and Back of the card or importing multiple cards in a long text (Front & Back separated by 3 hyphens --- and each card separated by 3 equal signs ===). The Front can have your question and the Back can have the answer. The Front & Back text supports Markdown and also LaTeX for Math formulas. So you can format text such as bold, italics, text color, text highlight, headings, links, images etc. You can also include diagrams (photos) in it. To use coloured text, use curly bracket format: {red}coloured text{} or {#FF0000}coloured text{} To highlight text, use square bracket format: [red]highlighted text[] or [#FF0000]highlighted text[] - Organize your flashcards into decks and folders for each subject as needed. Cards can belong to multiple decks at the same time. Decks and folders can also have subdecks and subfolders. - Practice decks or just bookmarked cards. - After reviewing the question on the front of the card, tap the card to flip it and reveal the answer on the back. Swipe RIGHT if the card was easy, LEFT if it you forgot it, or DOWN if you remembered but took some effort and would like to review again. - Once the whole deck is practiced, Crammer tells you how long you took to practice, and how many cards were hard. - Once you have reviewed a deck, you can instantly practice again with just a single tap. - Crammer notifies you if there's some card which you are constantly failing as it might be poorly designed. You can edit it to improve it. Make sure to swipe and reset its practice history after such fixes. - Swipe/Right Click on Mac to Bookmark important cards, decks, and folders for easy access. - Swipe/Right Click on Mac to Archive cards, decks, and folders which you no longer need. - Supports multiple choice questions (e.g. a, b, c, d). Use "1." before each option in markdown and it will automatically be rendered as a list of options. A setting lets you switch between numerical or alphabetical options. - All your decks, folders, and flashcards are seamlessly auto-synced across all your devices using iCloud. So you can create them on iPad/Mac and access them on iPhone. - All features are free. No Ads. No subscriptions. - Crammer is available on iPhone, iPad, and Mac. Supported keyboard shortcuts on Mac: - Enter or Spacebar to flip card - Left, Down and Right arrow keys for Hard, Again, and Easy ratings - Command + Z to undo a rating and go back to previous card - When editing a card, right click text to add photo Crammer lets you create unlimited flashcards, decks and folders for FREE.
