This App Store Award winner makes mental math, reading comprehension, and vocabulary-building fun with its easy-to-play mini-games. Here are our five favorites for getting our gray matter fired up.

1. Sharpen your synapses in Purchasing
How much does that daily latte habit cost you each year? In this mini-game, you’ll try to tally the annual cost of common recurring splurges (morning muffin, a new pair of sneakers), all in your head! Multiple choice answers make the task more doable than it might sound.
Potential brain gain: Sharper mental-math skills

2. Expel expendable words in Brevity
In this lightning-fast word game, tap superfluous words in a sentence as quickly as you can. (“The crowd completely filled the auditorium,” for example, can lose “completely.”) It’s a race against the clock—with props for being especially speedy.
Potential brain gain: Succinct self-expression

3. Rally your recall in Sequencing
Listen to a series of instructions, directions, or dates, then order them sequentially. Apply the chunking technique to score with this one!
Potential brain gain: Mastery of a super-practical memorization technique

4. Express yourself in Eloquence
Alter the tone of a sentence by changing the highlighted word. Type as many options as you can before time runs out!
Potential brain gain: More nuanced communication

5. Shoot for the moon in Agility
Keep your rocket ship flying ever higher by tapping words most closely related to each other (like bequest and gift, or litigious and combative). The higher you fly, the trickier this game gets.
Potential brain gain: Quicker access to just the right word
