A fun and didactic app to learn computer science algorithms!

Support, feedback, feature / algorithms requests: support (at) algorithmshq.com

Version 2023.1 (Apr. 2023)

• New linear data structure with Linked Lists! With a view on the memory to see where data is allocated and accessed with pointers.
• Minimum iOS version is now 12.4

Version 2020.1 (Mar. 2020)

• Updated for iOS 13 (dark mode)
• Fixed UI layout glitches for iPad Pros with bigger screen resolutions

• Fixed a UI bug where undoing an assignment to a variable moved the value from the wrong place;
• Fixed a random crash occurring when 'Done' was tapped while an animation was running;
• Fixed a random crash while animating Queues or Stacks with high speed and auto-generation of the next method to execute;

Version 2017.1 (Mar. 2017)

Linear Data Structures, with:

• Queue (array implementation)
• Stack (array implementation)
• Choose which function to execute next on a data structure, or
• Run a scenario that automatically chooses what function to execute.
• Choose the size of the data structure (up to 500 elements) and pre-fill amount.

Bug fixes:

• fixed rare crash with sending mail in portrait.

Version 1.1.0 (Nov. 2015)

New features!

• 2 new sorting algorithms: Gnome and Cocktail sort.
• Algorithms can animate even faster. Now you need only a bit of patience for Bubble sort and 500 values.

Fixes:

• support for iOS9 (fixed crashes)
• Comparator now shows the correct index at the bottom.

Release notes

Version 1.0.2 (Oct. 2014)

• Hotfix for iOS 8 compatibility

Version 1.0.1 (Jan. 2014)

• iOS 7 support
