Barcode scanning made simple! Use this powerful app to easily scan over 30 different types of barcodes, including QR, UPC, GS1, Data Matrix, PDF417, DotCode, and many others. The Cognex Barcode Scanners application reads all major barcode symbologies, including Aztec Code, Codabar, Code 11, Code 25 (Interleaved, Industrial, COOP, Matrix and ITF-14), Code 39, Code 93, Code 128, Data Matrix, DotCode, EAN, ISBN, GS1 DataBar, MaxiCode, MSI Plessey, PDF417, Micro PDF417, Postal Codes, QR Code (Micro and Standard), TELEPEN and UPC barcode types, as well as GS1 sub-types like GS1 QR Code, GS1 Data Matrix and GS1-128. The app also provides powerful parsers to examine industry standard formatted barcodes more easily such as AAMVA (US and Canadian Driver’s Licenses), GS1, IUID, Structured Carrier Messages (MaxiCode), and more!

BasicATTCalc

Basic Attenuator Calculator (BasicATTCalc) helps you calculate various resistive attenuators which are used in many audio, video and RF circuit design applications. The standard resistance values based on E-series numbers are outputted in inputting necessary conditions such as source impedance, load impedance and attenuation. Features The calculable attenuators and impedance converters are as follows: - Type T - Type Pi (π) - Type H - Type O - Type Bridged T - Type Bridged H - Type L (Impedance converter) - Type U (Impedance converter) Calculated resistance values are displayed with ideal values or the following E-series number specified either. E12, E24, E48, E96, E192 The most suitable values are calculated in selecting priority calculation whether Simple or Precision. - Simple: Perform calculations that the nearest values are derived to desired impedances and attenuation by the simple structure - Precision: Perform calculations that the nearest values are derived to desired impedances and attenuation by consisting of up to 4 resistors per an element In addition to resistance values, this application provides you with input impedance, output impedance and calculated attenuation with mismatch loss. If necessary, it is able to calculate power dissipated by each resistor and parameters such as reflection coefficient, VSWR, return loss and mismatch loss. Attention Because the standard resistors are used, the following restriction is set up. - Range of resistance value: 1Ω ~ 10MΩ (except ideal values)

Verdict
The clearest difference is price: Barcode Scanners at Free against BasicATTCalc's $1.99. Barcode Scanners also leads on update cadence (every 5 months vs every 29 months) and iOS requirement (9.0 vs 14.5). On ads, in-app purchases and device support there is nothing between them.
