Feature checklists make every tool look equivalent. This table leads with the three things that actually differ — what it costs you before it works, whether your files leave your device, and where the free version stops.

| What it does | A chromatic tuner that listens through your microphone and shows cents off | Stream independent music in full, and buy it as lossless files if you want it | Fourteen small experiments that let you build a rhythm and see harmony move | Free scanned sheet music for almost the entire classical repertoire |

| Where it stops | It needs a quiet room and a decent microphone — background noise and very low notes confuse the pitch detection. | Free streaming is capped at a few plays per release before it nudges you to buy, and the catalogue is only what artists chose to upload. | These are teaching toys rather than a DAW — Song Maker caps you at a short loop and exports only MIDI or WAV. | Non-subscribers wait a few seconds per download, scan quality varies wildly, and copyright status is stated per country — you have to check your own. |
