Songsterr Tabs & Chords, developed by Guitar Tabs LLC, is a subscription-based multimedia app available exclusively on iPhone. It provides access to a vast catalog of over 800,000 accurate guitar, bass, and drum tabs and chords, all with free full-length playback. As a subscription-based app, the free version allows you to view and playback all the tabs, while the paid version offers unlimited access to advanced features like Speed Control, Loop, Solo, Mute, Pitch Shifting, etc. for a monthly subscription of $9.99 USD (pricing may vary in countries outside the U.S.).

One of the most impressive features of Songsterr Tabs & Chords is its realistic guitar engine, which allows you to learn and play along with the app. Additionally, the app provides multiple instruments for most songs, including guitar, bass, drums, vocal, and more. With its Speed Control feature, you can slow down tab playback up to 15% to learn difficult parts, and its Loop feature allows you to play back selected measures over and over again. You can also use the app's offline mode to view and playback previously opened tabs offline, and its Chromatic Tuner to tune your guitar via mic or adaptors like iRig.
