Little Go is a free and open source iOS application that lets you play the game of Go on the iPhone or iPad. You can play against another human (on the same device), or against the computer. The computer player is powered by the open source software library Fuego (http://fuego.sf.net/). The minimum requirement for running this version of Little Go is iOS 16.0. Features: - Board sizes between 7x7 and 19x19 (start a new game to change the board size) - Let the computer player suggest a move or immediately play the move for you - Calculate the score at any time during the game (area scoring is the default, territory scoring can be selected at the start of a new game) - Adjust the computer's playing strength and resign behaviour by selecting from a number of presets, or by fine-tuning advanced settings - Play even games, or games with 2-9 handicap stones (fixed stone placement) - Select from 5 pre-defined rulesets when you start a new game, or adjust game rules to your preference (komi, ko rule, area/territory scoring system, number of passes to end game, resume play by alternating/non-alternating play, four passes end game) - Optionally play with time limits (Main time only, Overtime only, Main time + Overtime), with a choice from 5 Overtime systems - Place arbitrary black and white stones for initial board setup before a game starts - View board positions for moves played earlier during the game - View and create game variations - Discard moves (aka "undo") - Display move numbers and coordinate labels - Zoom & scroll board - Create and edit board and move annotations (e.g. good/bad move, good position for black/white, etc.) and add textual notes to a position - Mark intersections on the board with symbols, markers and labels, and draw arrows or lines on the board - Display player influence (aka territory statistics) for an estimate who owns an area - Computer vs. computer game for entertainment - Save & load games to/from the archive using the SGF file format - Support for almost all properties of the SGF file format, with strict conformance to the specification - Use file sharing to transfer saved games from your iOS device to your computer, and vice versa - Import/export game files from/to other apps on your device (e.g. Mail, DropBox) - In-app user manual - Submit bug report email from inside the app (yes, this *is* a feature :-)) - For the technically inclined: Watch what happens behind the scenes when Little Go and Fuego talk to each other over the Go Text Protocol (GTP) Your contribution in any form (coding, UI design, testing, bug reports, creating an app video preview, website design) is welcome - please contact me or visit the support website to find out more. A note about the project state: Several years of development have gone into Little Go since its inception in January 2011. The app now has a feature set that is, I believe, quite nice :-) for a free program. My main focus therefore lies on fixing any remaining bugs (of which I am sure there are plenty) and keeping the app running under future versions of iOS.

Verdict
The clearest difference is review sentiment: Mind Trex at 96% against Little Go's 50%. Mind Trex also leads on rating (5.0 vs 3.3) and iOS requirement (12.0 vs 16.0). Little Go's advantage is ads (none vs shown) and update cadence (every 4 months vs every 14 months). On price, in-app purchases and device support there is nothing between them.
