My Android MIDI chord controller just hit 100 downloads, and I'd love some honest opinions

Hey everyone! A while ago I started building MiChord , a small Android app that turns your phone into a MIDI controller. It just passed 100 downloads , which is a small number but a big deal for me. 🎉 What it does: Chord-aware keyboard: pick a key and scale, and every button plays a chord that fits, so you can't hit a "wrong" chord. Many scales: major, minor, harmonic minor, pentatonic, blues, dorian, mixolydian and more, and you can switch mid-performance.

痛点：不擅长键盘的卧室制作人想快速试听和弦进行，但缺少一个能在手机上保持在调内、直接连DAW的MIDI和弦控制器。

目标用户：卧室音乐制作人、beatmaker、EDM/lo-fi 创作者，尤其是不会弹键盘、习惯在手机上随手记录灵感的人

证据：It just passed 100 downloads, which is a small number but a big deal for me. / I built it because I wanted a quick way to sketch chord progressions without sitting at a full keyboard. I'm also not a great keyboard player, so having something that keeps you in key helps a lot. / almost every production subreddit bans self-promotion

变现：免费版限制音阶/播放模式，内购 $4.99–9.99 一次性解锁全部功能；或订阅 $1.99/月提供音阶包、和弦预设包与DAW模板捆绑

MVP：用 Kotlin + Android MIDI API 做 4x4 和弦网格：6 种常用音阶锁定 + 顺阶和弦自动生成 + USB/BLE MIDI 输出 + 3 组预设保存，2 周内可上线；暂时不做 DAW transport、joystick 与琶音器

竞品：Scaler 2、Captain Chords、ChordJam、Cthulhu、Tonality、Orca

摘要：作者独立开发了 Android MIDI 和弦控制器 MiChord，支持锁定调式/音阶防止弹错和弦、多种演奏模式、摇杆 pitch bend 与 USB MIDI 连接 Ableton/FL Studio 等 DAW，刚突破 100 次下载。发帖目的是求反馈，没有收入数据也没有用户付费佐证，只反映出一个被自己验证的小众需求：不会键盘的人需要移动端和弦草稿工具。桌面端竞品（Scaler、Captain Chords）成熟，但移动端仍有空位，单人 2 周可做出同类 MVP。
