The catalog includes more than 1,000 classical and public-domain songs, including pieces by Beethoven and Bach. Courses run from beginner through pro levels, and all you need is a keyboard and a device to run the app on.\n\nAt roughly $16 a year, the discounted price undercuts a single hour of in-person lessons, which is the actual selling point: not that an app replaces a teacher, but that trying one costs almost nothing. The $899 sticker price is also doing a lot of work here, since list prices on flash sales like this one exist mainly to make the markdown look dramatic.\n\nReal-time pitch detection from a microphone or MIDI keyboard has been a staple of piano apps for years. Calling it \"AI-powered learning\" is accurate, but it's also a reminder that the label does more marketing work than technical work.","[\"flowkey\",\"piano-lessons\",\"deals\",\"ai-features\"]","2026-10-04T09:00:00.000Z","2026-10-06T13:22:21.765Z","2026-10-06T13:22:26.009Z","published",null,[24,30],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"The article states the StackSocial deal runs 'through Oct. 4' but today's date is Oct. 6, 2026, so the sale window has already lapsed — confirm the current expiration date (or that the deal is still live) before republishing.","resolved",{"id":31,"reviewer":26,"round":32,"reason":33,"status":29},"editor-r2",2,"The expired-deal framing resolves the dating issue, but drop or attribute the unsupported market claims — 'AI practice tools are eating into beginner lesson books rather than studio teachers' and 'StackSocial routinely relist expired offers at the same or a slightly different price' are asserted as fact with nothing in the source to back them.","deals",[36,37,34,38],"flowkey","piano-lessons","ai-features",[40],{"name":41,"url":42},"Mashable","https:\u002F\u002Fmashable.com\u002Flife\u002Foct-4-flowkey-classic-plan-5-year-subscription",0,{"sections":45},[46,51,56,61,65,70,75,80,85,90,95,100,105,110],{"name":47,"slug":48,"count":49,"latest_published_at":50},"AI","ai",6347,"2026-10-06T07:49:07.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Security","security",879,"2026-10-06T00:00:38.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Policy","policy",463,"2026-10-05T23:16:24.000Z",{"name":62,"slug":34,"count":63,"latest_published_at":64},"Deals",374,"2026-10-06T09:00:00.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Hardware","hardware",211,"2026-10-05T21:14:08.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",182,"2026-10-05T18:58:12.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Consumer Tech","consumer-tech",162,"2026-10-06T09:00:14.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Software","software",103,"2026-10-05T18:23:19.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"Dev Tools","dev-tools",99,"2026-10-05T10:47:06.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Startups","startups",96,"2026-10-05T20:24:09.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Gaming","gaming",54,"2026-10-05T19:07:04.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"General","general",53,"2026-10-05T22:05:42.000Z",{"name":106,"slug":107,"count":108,"latest_published_at":109},"Reviews","reviews",33,"2026-10-05T11:57:17.000Z",{"name":111,"slug":112,"count":113,"latest_published_at":114},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
