Resono: Tinnitus Relief Sounds

Resono is a sound app built around one problem: the ringing that shows up the moment a room goes quiet. It combines sound mixing, frequency matching, and notched sound in one place, with playback that keeps going in the background and through a locked screen - the exact spot where most sound apps for tinnitus quietly fail.

WHAT'S INSIDE
- A library of masking sounds - synthesized noise colors and natural textures - that you can mix together, each at its own volume, to build a layer that actually covers your ringing instead of just sitting next to it
- Frequency matching from 100Hz to 15,000Hz on a slider, so you can dial in toward the pitch you actually hear, rather than picking from a handful of preset tones
- Notched sound, generated in real time to match the frequency you matched - not a pre-rendered band that happens to be close, but a filter built around your specific match
- A sleep timer with a fade-out, so the sound eases away instead of cutting off and waking you
- Background and lock-screen playback that keeps running through a phone call, a text notification, or the screen going dark - built specifically because that's where competing apps break

BUILT FOR NIGHT, NOT FOR SHOWING OFF
There's nothing to set up before bed beyond picking sounds and hitting play. No account, no onboarding you have to sit through every night, no ads that can interrupt playback right when you're finally drifting off.

WHAT RESONO IS - AND WHAT IT ISN'T
Resono is a masking and relaxation sound tool. It is not a medical device, and it does not diagnose, treat, or cure tinnitus or any hearing condition. If you're dealing with persistent or worsening ringing in your ears, talk to a doctor or an audiologist - this app is a comfort tool to sit alongside that care, not a substitute for it.

FREQUENTLY ASKED QUESTIONS
Q: Will this get rid of my tinnitus?
A: No app can promise that, and we won't claim it. Resono gives you sound to mask and relax with. If your ringing is a medical concern, please see a professional.

Q: What's the difference between the starting version and Pro?
A: The starting version includes 8 masking sounds and basic frequency matching. Pro unlocks the full sound library, notched sound, the ability to save your own mix presets, per-ear volume balance, and a listening stats view showing your sessions over time.

Q: Does the sound actually stop when I fall asleep, or does it play all night?
A: You choose. Set a sleep timer with a gentle fade-out, or leave it running all night - it's entirely up to you.

Q: Will playback stop if I get a call or lock my phone?
A: No. Resono is built to keep playing through calls, notifications, and a locked screen, which is exactly where many similar apps cut out.

Q: Is there advertising in this app?
A: None, anywhere, ever - Resono has zero ad code. It's fully supported by an optional one-time Pro purchase, never a subscription and never an ad interruption.

Q: Do I need an account or internet connection?
A: No. Everything runs on your device, offline, with no sign-up of any kind.

RESONO PRO
A single one-time purchase unlocks the full library, notched sound, saved mix presets, per-ear balance, and listening stats, forever - no subscription, no recurring charge. The starting tier already includes real masking sound and frequency matching, so you can try the core idea before deciding whether Pro is worth it for you.
