Ohmulator vs Passmint

Makes Ohm's Law simple! Ohmulator is a simple, yet robust, electric circuit calculator that enables you to quickly find the unknown variables of a circuit. Ohmulator allows you to easily adjust unit types on the fly (eg. milli Amps, Amps, kilo Amps), which means no prior conversion! Enter two known variables (from: I = Current, R = Resistance, V = Voltage, P = Power), set preferred units, then Ohmulator will calculate and return the previously unknown values. Also an effective (total) resistance calculator. What two App Store reviewers had to say about Ohmulator: "Great. Does what it says. Very good app. Stylish design." 5 Stars - Jamie1990jamie "Awesome app. It simply works. A must have for the radioamateur or electronic nerd. Nice to have the watt law as well." 5 Stars - Per67 Also available for macOS on the Mac App Store.

Passmint turns loyalty cards, event tickets, boarding passes and train tickets into passes you can add to Apple Wallet, and keeps every one of them in one place. Stop digging through screenshots and email attachments. BRING YOUR CARDS OVER Already keep your cards in another app? Take a screenshot of each one and pick them all at once. Passmint finds every barcode, works out which store each card belongs to and sets them all up for you. Several cards on one screenshot is fine. You check the list, then add them all in one go. The screenshots are read on your iPhone and never uploaded. YOUR STORE CARDS, READY TO GO Pick your shop from hundreds of stores across Europe, the Americas and beyond, then scan or type your card number. The pass takes the store's colors, and the barcode is drawn the way the real card prints it, so the register reads it the first time. EVERY WAY TO ADD A PASS • Scan a barcode or QR code with your camera: the frame locks onto the code as soon as it finds it • Import a photo or a screenshot, or pick one from your recent photos • Import a PDF, including multi-page tickets • Bring several cards over at once from screenshots • Start from a ready-made design • Type a code in by hand, with a live preview before you save Passmint reads the code and the ticket around it, and fills in the rest for you. Boarding passes, train and coach tickets and event tickets are recognized on their own, so the route, times, seat, venue and date land in the right fields without you typing them. All of it is read on your iPhone. READY-MADE DESIGNS Browse a growing gallery of illustrated pass designs, from concert nights to seasonal parties. Pick one, add your own code, and your ticket looks like it was made for the occasion. ADD TO APPLE WALLET One tap adds a pass to Apple Wallet, right inside the app, ready at the gate or the counter. Edit a pass later and add it again to update the copy in Wallet. KEEP EVERYTHING IN ORDER Passmint is a wallet, not just a pass maker. It holds your passes and keeps them tidy. • Search across every pass you own • Filter by type, or group loyalty cards, events, travel and everything else into their own sections • Pin the pass you need next to the top • Drag to reorder passes, and whole categories too • Archive old passes instead of deleting them • Past tickets move into their own section on their own, from the date on the ticket • Switch between full cards and a compact grid MAKE THEM LOOK RIGHT • Pick any color, or build a two-color gradient and drag the direction where you want it • Use your own photo as the card background, and drag to frame it • Add a subtle pattern • Edit any field, rename any label, add fields of your own EVERY COMMON CODE TYPE QR, Aztec, PDF417, Data Matrix, Code 128, Code 39, Code 93, Codabar, ITF-14, EAN-13, EAN-8, UPC-A and UPC-E. Passmint draws the right symbology at a size a scanner reads the first time. WORKS OFFLINE Creating, editing, searching and showing a pass all happen on your iPhone, so no signal is needed at the gate. The screen brightens by itself when you open a pass, so the scanner picks up the barcode. SEND SOMEONE A PASS Share a ticket as a file. They open it and it lands in their Passmint, barcode and all. Put a passphrase on it if you want. BACK UP YOUR PASSES Export everything to an encrypted file that you keep, and import it back on a new iPhone. PRIVATE BY DESIGN No account, no sign-up, no password, no ads. Your passes stay on your device. A pass leaves it only when you add it to Apple Wallet: it is signed and immediately discarded. Passmint does not sell or share your pass data, and is not affiliated with the stores it lists. 18 LANGUAGES English, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Czech, Romanian, Swedish, Danish, Norwegian, Finnish, Russian, Turkish, Greek and Ukrainian.
