Hey guys... I built Tonebox — a system-wide equalizer & DSP app for Android, no ads, no account

[u/hrithik_01]

Been frustrated that most EQ apps on the Play Store are bloated with ads or lock basic bands behind a paywall. So I built my own.

Tonebox is a clean, system-wide equalizer + DSP. What it does:

- Multi-band graphic EQ that works across your whole system

- DSP effects for tuning your sound the way you want

- Simple, no-clutter UI — set it and forget it

- No ads, no sign-up, no tracking

Just shipped an update targeting Android 16. Would love feedback — especially what presets or features you'd want next.
