- Expressions should no longer get partly hidden by the iPhone camera (iOS change only)

- Fixed a bug where dragging one atom on another could result it the dragged atom being moved to the other side of an equations instead.

- Drag-and-drop is now less sensitive to hitting exactly the correct atom. Should improve user experience. - Powers now look better when the base also is a power

Fixed a crash

New feature: "Hold to factorize"! - To factorize a common factor from a sum, hold the desired factor for a short time. Then, one equal factor from each term will move towards the factor you hold. You can then drag it out to factorize the expression. - Factorize Expression button removed. - Some levels on World 9 have been modified to fit this new change. - Extra welcome screen for players who've reached world 9 to learn the new feature.

- Improved Daily Challenges UI - Fixed a bug where improving one of time/moves would overwrite a better time/moves - Fixed a sound bug when starting the game - Fixed a bug where selected difficulty did not match leader board display when returning to daily challenges from worlds.

- Removed Ads - Fixed a bug where leaderboard data was not submitted if you exited the Daily Challenge End screen too fast.

In addition to being updated when you complete a challenge, leaderboards are now also updated every 5 min. Giving yourself a new name no longer creates a new user. Other minor fixes with the leaderboard.

Daily Challenges now has a leaderboard for time and moves. Click "Time" or "Moves" headers to sort the leaderboard accordingly.

- Added move animation for factorizing expressions.

Game crashed. It no longer crashes.

App should be faster now.

Added animation for multiplying Fractions

Improved animation and fixed broken move goals and a broken tutorial.

Added in-game animation for some mathematical operations.

- Updated how numbers are factorized - Tapping powers now factorizes the power by reducing the exponent by 1 and moving one base factor out of the power - Adjusted move goals to fit these changes.

Fixed an issue with ads

- Fixed top UI not going away after explanation text - Added a new feature where top UI goes away but fades back in for non-permanent text. - Fixed a fraction bar collision issue. - Fixed Chapter Star count being wrong.

- Added videos to support levels that you can watch when selecting the "?" button. - Added an automatic fps check at the start of the game that turns off glow and fireworks if the users fps is too low. This should reduce freezes and crashes for users with older phones. - Added other optimizations to help with performance issues on older phones.

Hovering a term to the other side of an equation shows the sign flipping.

Added World numbers Cleaned up ads screen transitions
