A great music-making app recreating one of the all time great synthesizers on iOS is just one of our picks for this week’s “Awesome Apps of the Week.”

In addition, we’ve got a superb Twitter client app update, the world’s most popular battle royale game, and a gamebook RPG recreating some of the genre classics of the 1980s. Check out our selections below.

Moog Model D

Moog has created an app version of its original 1970 Minimoog keyboard — and it’s a bargain to snap up. Recreating the iconic synth, it allows you to create your own sounds by using the (in this case virtual) knobs and switches arrayed across the front of the keyboard. If you don’t want to do this, you can also download a variety of presets, which can be saved and shared from iCloud.

In addition, there’s a looper, an arpeggiator, a delay module, and a tool for bending the sound. You can hook up an external MIDI keyboard to play on, and even use it inside apps like GarageBand. If you’re a musician, this should be a “must have.”

Fortnite

I’ve covered Fortnite for the “Awesome Apps” roundup before, but it’s hard to ignore the biggest game in the world right now — especially when Epic Games keeps rolling out new weapons, game modes, and more.

The game’s big updates include the addition of a guided missile in battle royale mode, hunting rifle and crossbow availability in the limited-time Sniper Shootout game mode, and an egg launcher in place of the grenade launcher for Easter. There’s also now a text party chat, although there’s still no in-game voice chat. Finally, anti-aliasing at 4X is now supported on all devices, and there’s a new update system that prevents you from having to download massive packages from the App Store every time there’s a change.

For a complete list of fixes across mobile, console, and PC, you can check out Epic’s lengthy release notes for this patch. (If you haven’t played Fortnite yet, you should also check out my colleague Killian’s beginner’s guide for some tips.)

Twitterific

If you’re a Twitter user, I’d highly recommend Twitterific as an app which allows you to have more granular control over the micro-blogging social media service. This week, both the Mac and iOS version of Twitterific received an update, letting you attach videos of up to 140 seconds to tweets, as well as muffling and muting tweets that you don’t want to see or hear about.

Fighting Fantasy Classics

The great thing about the iOS gaming ecosystem is that, while there are always going to be mega-hits like the aforementioned Fortnite, there’s also room for more offbeat titles to become hits. Fighting Fantasy Classics is one such game. I found out about it based on a review from the folks at Touch Arcade, and it’s more than lived up to their gushing praises.

The interactive gamebook (think branching Kindle storybook with plenty of dice rolls) isn’t a genre I’ve got more than a passing familiarity with. Nonetheless, this game features remastered versions of several classic 1980s and 1990s text-based roleplaying adventures including Citadel of Chaos, Warlock of Firetop Mountain, City of Thieves, Forest of Doom, Caverns of the Snow Witch, and more. In other words, whether you’ve a newbie looking to find out what’s great about the genre or a long-time fan, it’s hard to see how you could go wrong with this.
