Where the facts come from. Platforms, price models and every feature tick come from the App Store listing, the Google Play listing or the maker's own page or manual, read on 2026-10-07, and the exact words relied on are kept with each row (open "Sources" on any card). Store ratings and review counts are the stores' own on that date, pulled through Sonar, an app-store analytics service. A feature is marked yes only when a listing, the maker or a manual says it; when none does, it is shown as unknown rather than as no.
How it was checked. Every row was researched once and then handed to a second, independent pass whose only job was to break it: open the same listings and pages, check every tick, every platform, every rating. Rows it could not confirm were corrected or marked unknown before publishing.
What this page does not measure yet. We have not yet entered the same eight-bar reference groove in every tool and timed it, or exported and re-imported the same score to check what survives the round trip. Until that test and its method are published here, the columns say what each tool claims to do, not how well.
Prices. Every price is in US dollars, read on 2026-10-07 on the store or page named next to it, with a link: Sweetwater, Musician's Friend or the maker's own store for gear and books, the US App Store's in-app purchase list or the maker's pricing page for apps. When a maker sells for less on its own website than in the app, both are shown. Prices change, so the date is part of the fact: check the store before you buy. Nothing on this page is an affiliate link.
Photos. Product photos and icons belong to their makers and publishers, taken from their own pages to show which product a card is about. Each card names its source; a maker who wants a photo removed can write to support@upbeat.studio.
