Sound Amplifier picks up the voices and sounds around you with your phone's microphone and plays them into your earphones in real time — so a soft-spoken friend, the TV across the room or a lecture from the back row comes through more clearly. Missed what someone just said? Tap Replay last 10s to hear the last 10 seconds again. Want the sound shaped for your own ears? Take the short Hearing Test and a personal EQ is built from your answers. Please note: Sound Amplifier is an everyday assistive listening tool. It is not a medical hearing aid and it does not diagnose hearing loss. LISTEN • Live amplification from 0 to +40 dB, with a live level meter • Replay the last 10 seconds — kept in memory only and cleared when you stop • Voice leveller that evens out loud and soft voices automatically • Noise reduction that cuts low rumble from air conditioning, traffic and wind TUNE • 3-band equalizer: bass, mid and treble, each ±12 dB • Presets for Speech, Music, Outdoor and Flat • A Personal preset created from your Hearing Test • Left/right balance for when one ear needs more HEARING TEST • Soft tones at 250, 500, 1,000, 2,000, 4,000 and 6,000 Hz, one ear at a time • Turn the result into a personal EQ with one tap • Hearing over time: compare later tests with your first one (changes under 10 dB are shown as no change) • Earphones or headphones are required, because each ear is tested separately MY SETUPS • Save up to 8 named setups — TV, restaurant, lecture — and bring one back with a tap SAFETY • A safety limiter caps loud peaks at a level you choose (-18 to 0 dBFS) • The app will not amplify through the phone's own speaker, where the microphone would pick the sound up again and howl • If your earphones disconnect, amplifying stops and a card explains why; reconnect them and tap Resume GOOD FOR • TV dialogue without turning the room volume up for everyone • Conversations in cafés, restaurants and family dinners • Lectures, sermons, meetings and guided tours • Birdsong and quiet sounds on a walk Tips: start with low amplification and raise it slowly. Wired earphones have the shortest delay; Bluetooth earphones work too but add a little lag. If you are worried about your hearing, please talk to a hearing professional.

Neko is a cozy proxy client for iPhone and iPad. Point it at the subscription or nodes you already have, and it turns them into a one-tap tunnel — wrapped in an interface you will actually enjoy opening. BRING YOUR OWN CONFIGURATION Neko is a client, not a service. It does not include, sell or provide proxy servers, subscriptions or bandwidth. You supply a subscription URL, or paste node links from a provider you trust — or from a server you run yourself. THE CAT IS THE STATUS No status bars to decipher. Neko's mascot mirrors your tunnel: curled up asleep when you are disconnected, ears perked while connecting, bright-eyed and blushing once you are protected, and zooming when traffic is really flying. FEATURES • One-tap connect — tap the button, or just tap the cat • Sniff — measure real latency for every node before you commit • Auto or manual — let the fastest node be picked for you, or choose it yourself • Feeds — keep several subscriptions and switch between them instantly • Routing modes — Smart Paw (rule-based), Roam Free (global) or Stay Home (direct) • Paw Prints — a live, readable log of what the engine is doing • Sakura light and Midnight dark themes, designed to match • Purr haptics and a little meow when you connect, both optional PROTOCOLS Shadowsocks, VMess, Trojan, VLESS and Hysteria2. IMPORT FORMATS Subscription URLs returning base64-encoded link lists or plain link lists, YAML configuration files in the widely used mihomo format, and individual node links pasted straight from your clipboard. PRIVACY BY DESIGN No account. No sign-up. No analytics, no advertising, no tracking of any kind. Your subscriptions, nodes and settings are stored only on your device, and Neko never sees your traffic — it runs entirely on your iPhone or iPad and connects only to the servers you configure. BUILT ON A FAST, OPEN CORE Neko is powered by meow-rs, an open-source proxy engine written in Rust and distributed under the MIT licence. It is compact and efficient enough to run comfortably inside an iOS network extension. PLEASE NOTE Neko requires your own proxy configuration to be useful — it ships with no servers and no free trial of any network service. You are responsible for using it in line with the laws that apply to you and with the terms of whichever provider you choose.
