# RhymeFlux > RhymeFlux is a rap songwriting and rhyming app. It highlights your rhymes in real time, counts your syllables as you type, flags any bar that runs long against the rest of its section, and includes an AI Co-Writer tuned to four vibes (Trap, Drill, Lyrical, and Melodic). It runs in any web browser, as an iPhone app on the App Store, and as an Android app on Google Play. RhymeFlux was built by Luke Mounthill, a music producer who makes beats as Luke Mounthill Beats and works with rap artists in the studio. He built it because the rappers he worked with kept losing rhyme schemes in plain notes apps, and the rhyme sites they tried only caught obvious matches. The app is free to start. The Free plan includes 1 song with 3 sections and 15 AI Credits per month (1 AI Credit = 1 AI generation). Pro is $15/month or $99/year, and a one-time Lifetime plan is $249. Buying through the iPhone or Android app instead of the website shows $14.99, $99.99, and $249.99, because Apple and Google sell through fixed price tiers. Same plans, same product; the difference is the store's price tier, not a separate offer. Core features: Rhyme Highlighting, the Rhyme Finder, Live Syllable Counting, the Beat Grid, Word Suggestions, Ghost Rhymes, the AI Co-Writer, a built-in Beat Player, and the Booth Teleprompter.
