Simple Circuit Builder vs ToolFlip

Description This is the BEST app to learn about Resistors and Circuit Resistance (Equivalent Resistance). This virtual lab provides an excellent environment for anyone who is interested in understanding series and parallel resistors, learning how to measure voltages across resistors, current through series and parallel circuits and solving simple circuits. Features - VERY SIMPLE and EASY TO USE, with up to eight component sections. - Component sections can easily be configured from five different types. - VIRTUAL "Hands On" experience using volt and amp meters. - Resistor values can easily be changed with a picker, keypad or using randomize button. - Circuit voltage can easily be changed from 1 to 1000 volts with a picker or a keypad. - The "Basics" screen make this app unique for the simplicity and speed of seeing the effects of "Opens" (resistor component with infinite resistance) and "Shorts" (resistor component with zero resistance). - FREE and NO ADVERTISEMENTS. - The circuit is always "LIVE" and immediately shows voltage, current and circuit resistance with any changes made to the circuit.

ToolFlip tells you what a tool is worth before you buy it or sell it. Point your camera at a power tool, hand tool, or piece of jobsite equipment. ToolFlip identifies it with AI, then gives you a realistic used-price range, a clear flip verdict, and everything you need to sell it fast. SCAN TOOLS - Instant AI identification from one photo (add extra angles when it matters) - Realistic used-price ranges, not wishful thinking - Buy/skip flip verdicts and a profit calculator - Scan history so every valuation stays on hand SELL FASTER - Ready-to-post listing copy written for you - One-tap ad poster to share on Facebook Marketplace, Craigslist, Kijiji, OfferUp, or eBay - Mark items sold and track what you actually made SCAN MATERIALS - Identify building materials: lumber, drywall, plywood, pipe, wire, insulation, and more - Price estimates by the sheet, stick, bag, roll, or foot - See nearby stores that carry what you scanned SHOPPING LISTS - Build material lists with quantities and a waste-factor toggle - Quantity estimator for sheets, studs, and coverage - Snap a paper list to import it, export as PDF, or share a live web link anyone can open in a browser (no app needed) FREE AND PRO Scan free every day. ToolFlip Pro unlocks unlimited scanning with a monthly or annual auto-renewing subscription (introductory pricing available). Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period; manage or cancel anytime in your Apple Account settings.
