Coin Tester. vs BigKeys Large Key Keyboard

Coin Tester is an advanced application that allows users to verify the authenticity of one-ounce gold and silver coins. The application uses the method of acoustic resonance (known as the ping test) and artificial intelligence to determine whether the user is dealing with a genuine coin. When struck, a coin vibrates and emits a unique sound, primarily influenced by its dimensions and the material it is made of. For example, a gold Maple Leaf will sound different than a silver Krugerrand when struck. An authentic gold or silver coin will produce a different sound than a counterfeit one. These differences are precisely used by the Coin Tester application. Interestingly, mints release coins each year with a newly physically minted vintage. Additionally, changes in the coin production process, wear and tear, and the appearance of patina on silver create minor differences that affect the sound of the coins. Using artificial intelligence, the Coin Tester application guides users through the coin verification process and assists in determining the authenticity of the product. We have access to a large database of new and circulating coins, allowing us to regularly add updates that include coins from new vintages. This ensures that the application functions accurately for all types of coins, regardless of their condition, type, or minting year. With subscriptions, you can access coin verification for a week, a month or a year.

Big, easy-to-read keys for seniors and anyone with low vision. Type in Messages, Mail and every other app with fewer typos. PAY ONCE One purchase, and BigKeys is yours. No subscription, no advertising, and nothing held back behind a later purchase — every feature on this page is included. MUCH BIGGER KEYS Each row of the usual keyboard is split across two rows, so every key is roughly twice as wide. The letters grow with them. Four sizes, from Medium up to about three times the standard key. MORE OF YOUR SCREEN, SAME BIG KEYS Turn on the thin strip above the keys and the keyboard takes less of the screen, while every key stays exactly as big. BIG EMOJI Tap the smiley key next to 123 for the iPhone's own emoji, as big as the keys. The ones you sent last come first. SEE THE KEY BEFORE YOU COMMIT Nothing is typed when you touch a key. Hold your finger down and the letter appears above it, very large. If it is the wrong one, slide to the right one and let go. Only then is it typed. COLOURS THAT WORK FOR YOUR EYES Yellow on black, white on black, black on yellow, black on white, or matching your iPhone's light and dark mode. If bright screens are painful, the dark themes are not a novelty — they are the point. HEAR WHAT YOU TYPE BigKeys can speak each key as your finger passes over it, and each word as you finish it. It works alongside VoiceOver rather than talking over it. WORD SUGGESTIONS Suggestions appear in large type as you type, and BigKeys learns the words you use most. All of it happens on your iPhone. TEN LANGUAGES, ONE KEYBOARD English, Hebrew, Spanish, French, German, Italian, Portuguese, Dutch, Russian and Arabic — including right-to-left. Add it once and switch between them from the keyboard. NOTHING LEAVES YOUR IPHONE BigKeys never asks for "Allow Full Access". You can check: Settings > General > Keyboard > Keyboards > BigKeys. There is no such switch. Without it iOS will not let a keyboard reach the network at all, so nothing you type can go anywhere. BEFORE YOU BUY iOS never allows any third-party keyboard into a password field. Apple's own keyboard appears instead. This is true of every keyboard app on the App Store and cannot be changed. Setting BigKeys up takes about a minute. The app walks you through it one step at a time, in large print, and tells you when it is working.
