Puzzle Sidekick is a set of tools, reference material, and links for anyone who plays The Game, solves puzzle hunts, plays Alternate Reality Games, participates in transmedia storytelling, or solves puzzle trails. The tools range from decoder-ring style codebreaking to countdown timer prediction. The reference material includes word frequency, morse code, semaphore, and more. *NOTE* This application is for iOS 7 only. If you are stuck on an earlier version of iOS, you can still use the “ARG Tools” app. Included in this package are: • Dictionary: ◦ Search for words matching patterns (e.g. all possible crossword answers) • Encoding/Decoding: ◦ ROT-N (from 1 to 26, including ROT-13) ◦ BASE64 ◦ Vigenere / Beaufort ◦ Transposition ◦ Substitution • Character Encodings ◦ Baudot Code ◦ Braille ◦ Fingerspelling ◦ Letters to numbers (1..26) and ASCII ◦ Nautical Flags ◦ Moon Alphabet ◦ Morse Code (two representations) ◦ Myst D'ni Glyphs ◦ Phonetic alphabet ◦ Pigpen Cipher (two representations) ◦ Roman Numerals ◦ Semaphore (two representations) • Tools and Reference ◦ Telephone digits to letters (2=ABC, 3=DEF, etc.), optionally constrained by dictionary words. 228 becomes ACT, BAT, and CAT ◦ A red/green/blue color mixer with hex and decimal values ◦ A list of common English words, letters, letter pairs ◦ Billiard ball colors ◦ Books of the Bible ◦ Countdown timer prediction ◦ Dart board scoring ◦ Dewey Decimal System ◦ ISO Country Codes ◦ Mathematical Constants, Prime Numbers ◦ Music Notes and their Frequencies ◦ Password Generator ◦ Periodic Table ◦ Planets ◦ Resistor Color Codes ◦ Ring Sizes ◦ Zodiac, Chinese Zodiac ◦ Quick access to Google, Wikipedia, Sudoku Step-Solving, Encyclopedia of Integer Sequences The design goals of this application include: • Easy to use in the field • Small enough to be downloadable over the air so you can quickly obtain it without WiFi access • Free-as-in-beer!
GC Wizard
This open-source tool collection offers a wide range of cryptographic, geographic, and scientific calculations. It's designed to assist with in-field mysteries and riddles, but its extensive features make it useful for many non-geocaching tasks.

The GC Wizard is an open-source tool collection. It was originally created to offer Geocachers an offline tool to support them with in-field mysteries and riddles. So, the GC Wizard contains numerous tools for simple cryptography, geographic and scientific calculations as well as hundreds of sets of various symbols. Meanwhile the project became very huge and might be practicable for many non-Geocaching issues. General • Formula Solver: For handling multi stage variables • Multi Decoder: Enter an unknown code and let several decoders and calculators interpret it in a row • More than 200 sets of Symbol Tables: Direct decoding symbols to characters; save own encoding as an image • Online Manual: Every tool has its own manual page Cryptography & Encodings • Alphabet Values (A = 1, B = 2, ...): Configurable alphabets with language specific special character handling • Braille graphical decoder: Type the points into a graphical interface; supports different languages • Book Cipher: Choose the correct system (e.g. Line + Letter Number or Section + Line + Word Number, ...), handle special characters and empty lines, ... • Enigma: A full working Enigma simulator incl. numerous possible settings • Esoteric Languages: Generators and interpretors for several esoteric programming languages like Brainf**k, Ook, Malbolge and Chef • Morse • Numeral Words: Lists of important numbers in different languages. For English + German there are parsers to identify even complex numeral words • Substitution and Vigenère Code Breakers: Try to find the solution without knowing the keys • Classic Codes: Playfair, Polybios, Railfence, ... • Historic codes: Caesar, Vigenènere, telegraph codes, ... • Military codes: ADFGX, Cipher Wheel, Tapir, ... • Technical encodings: BCD, CCITT, Hashes (incl. brute-force hash breaker), RSA, ... Coordinates • High precision coordinate algorithms which support precise calculations even with very long distances by always considering the earth's shape (ellipsoid) • Support of different ellipsoids, even other planets • Coordinate Formats: Support of UTM, MGRS, XYZ, SwissGrid, NAC, PlusCode, Geohash, ... • Waypoint Projection: Includes precise reverse projection • Open Map: Set own points and lines, measure paths, export as and import from GPX/KML; OpenStreetMap and satellite view • Variable Coordinate: Interpolate coordinate formulas if some parts of coordinate are not given. Show result on map • Cross bearing, Center point of two and three coordinates, different intersections of lines and circles, ... Science and Technology • Astronomy: Calculate position of sun and moon at a certain place and time • Color Space Converter: Convert color values between RGB, HSL, Hex, CMYK, ... • Countries: ISO, calling and vehicle registration codes, flags • Date and Time functions: Weekday, time differences, ... • Irrational Numbers: π, φ and e: Show and search up to > 1 Mio. digits • Number sequences: Factorial, Fibonacci and Co. • Numeral Systems: Converts decimal to binary, hexadecimal, ... • Periodic Table of the Elements: Interactive view; lists which order the elements by any criterion • Phone Keys: Converts classic phone keys to letters. Supports phone model specific behaviours • Prime Numbers: Search prime numbers up to 1 Mio. • Segment Display: Graphical interface for decoding and encoding 7 to 16 segment displays • Unit Converter: Length, Volume, Pressure, Power and many more; convert between common units incl. prefixes like micro and kilo • Apparent Temperature, Cross Sums, DTMF, Keyboard layouts, Projectiles, Resistor codes, ... Images and Files • Hex Viewer • Exif/Metadata Viewer • Analyse frames of Animated Images • Color corrections: Adjust contrast, saturation, edge detection, ... • Search for Hidden Data or hidden archives • Read QR/Barcodes from images, create them from binary input

Verdict
The clearest difference is update cadence: GC Wizard at every 6 weeks against Puzzle Sidekick's every 20 months. Puzzle Sidekick's advantage is ratings volume (109 vs 5) and iOS requirement (12.0 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.9 for Puzzle Sidekick against 4.8 for GC Wizard. That said, the two scores are not equally well evidenced: Puzzle Sidekick has 109 ratings behind it against 5, so its average is the more settled of the two.
Puzzle Sidekick ships an update every 20 months, GC Wizard every 6 weeks. The most recent releases landed on September 23, 2026 and September 10, 2026 respectively.
