bit shifty :: the most powerful programmerβs calculator you will ever need Feature-rich, easy to use, and computationally powerful β with unmatched capabilities for doing calculations with extremely large integers (10k binary digits). If you need a precise answer without number rounding or floating point calculations, want to work offline, or donβt want to be constrained by numbers that fit in one machine register, this app will surpass your expectations. Extremely large integers are easily input, viewed, and interacted with via a scrollable keyboard screen. The following functions are currently included: Arithmetic: - Addition - Subtraction - Multiplication - Division - Modulo - 2^x - EE Bit logic: - AND - NAND - OR - NOR - XOR - XNOR Bitwise: - Set bit - Clear bit - Toggle bit - Left shift - Right shift Integer calculations can use any combination of the binary, octal, decimal, or hexadecimal number bases, and a base is easily switched to another. Machine word sizes for input and output integers, and associated calculations, can be set to 8, 16, 32, 64, or 128 bits. Furthermore, inputs and output do not need to be the same machine word size. Input and output integers can also be either big endian or little endian, or a combination of both. Additionally, bit shifts are user selectable to either trim the bits beyond the current machine word or extend the number of bits in the integer. The integer separator is settable to a number of different options, e.g., comma, period, space, etc. And as an added bonus, the full calculation description (integers, number bases, number representation, endianness, selected calculation and machine word size) can be forwarded to the destination of your choice as a JSON formatted string. Annual subscription USD 9.99/year. Subscription auto-renews unless cancelled prior to start of new subscription term. Subscription includes access to all 18 current calculator functions and access to all new features introduced during subscription term.

Swoop

Write SwiftUI on your phone, watch it run, and paste it into Xcode. Swoop is a canvas for postcard-sized components. Type one, press play, and it runs for real β springs, timing and trigonometry computed on the device at the frame rate you feel. Copy hands back plain SwiftUI that compiles. Most SwiftUI apps are catalogues you browse. This is the one where you write it. WHAT IT PLAYS Swoop runs a documented subset of SwiftUI, on device. β’ Text, Image, Button, Toggle, Spacer, Divider β’ VStack, HStack, ZStack, ForEach, TimelineView β’ Circle, Capsule, Rectangle, RoundedRectangle β’ frame, padding, offset, opacity, scaleEffect, rotationEffect, zIndex β’ fill, stroke, trim, background, overlay, clipShape, shadow β’ animation, onAppear, symbolEffect, sensoryFeedback β’ @State, helper funcs, computed views, if/else, ranges β’ sin, cos, tan, sqrt, pow, min, max, .pi If Swoop cannot play something exactly the way Xcode would, it refuses and points at the line rather than guessing. What you copy always compiles. Swoop is for one component at postcard size β not for building whole screens on a phone. ScrollView, List, NavigationStack, GeometryReader and TextField are deliberately not included. A REAL EDITOR β’ Line numbers and syntax colour β’ Autocorrect, smart quotes and autocapitalisation switched off β’ Every file in your library previews itself, running, in the list POST IT AND RECORD IT β’ Publish a component to the community, free, under your username β’ Anyone can play it and take the source β’ Record three seconds of it running and share the video β’ Like and view counts on everything published PRIVACY β’ Your files are saved on your phone β’ Nothing is uploaded, read by us, or used to train anything β’ A file leaves the device only when you publish or share it β’ Writing, playing and copying never need an account β’ Sign in with Apple or Google only to publish or like β’ Delete your account from inside the app, any time SWOOP PRO β’ A profile page β your picture and a grid of your work β’ Clean recordings, without the Swoop mark β’ Sign a recording with your avatar and username β’ Backdrops for recordings β’ Post a component without handing over the source Writing, playing, copying and publishing stay free. Requires iPhone, iOS 17 or later. Swoop is an independent product and is not affiliated with or endorsed by Apple Inc. Swift, SwiftUI and Xcode are trademarks of Apple Inc.

Verdict
The clearest difference is in-app purchases: Swoop at none against bit shifty's 1. Swoop also leads on update cadence (weekly vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
