BusJam Nap

**BusJam** is a short-rest companion for the bus or subway ride to and from work — for the minutes you want to truly switch off, not just zone out. The commute window is awkward: too short to really sleep, too tired to stay alert. BusJam shapes the listening into an **Alpha → Theta → Alpha** binaural-beat arc that helps you drop into a rest state quickly, hold a deeper trough in the middle, and surface gently before your stop. ### Why Alpha → Theta → Alpha - **Alpha (around 10 Hz, opening segment)** — release tension and settle into a meditative calm. - **Theta (around 6 Hz, middle segment)** — slip into a deeper rest-and-recovery window within a few minutes. - **Alpha (around 10 Hz, closing segment)** — wake up gently with a softer return to alertness. The default 20-minute session is 5 min alpha / 10 min theta / 5 min alpha. Adjust the total length minute-by-minute and the same 1 : 2 : 1 ratio rescales automatically. ### Key features ■ Real-time binaural synthesis • Alpha and theta tones generated live with AVAudioEngine + custom oscillators — no pre-rendered audio • Headphones or earbuds recommended ■ Minute-by-minute timer • 1 to 60 minutes, your choice • Alpha–Theta–Alpha ratio (1 : 2 : 1) holds at any duration ■ Calm, direct controls • "Sleep well" to start • "Hold on" to pause, "Wake me up" to end ■ Mix-your-own nature soundscape • Categories: waves, wind, rain, birds, stream, subway, pink noise, campfire, waterfall • Layer multiple categories simultaneously to find the mix that suits *you* • Pick a variant within each category to fine-tune the mood • All audio is sourced under commercial-use-allowed, no-attribution-required licenses (Mixkit, Freesound CC0, locally generated) ■ Background playback • Lock the screen or switch apps — the session keeps running • Standard iOS background audio mode ■ Gentle session-end chime • A short, soft bell rings as the closing alpha segment ends, so you don't sleep past your stop ### Who BusJam is for - Commuters who want a true short rest on the bus or subway - Knowledge workers taking 15–20 minute power naps before re-focusing - Anyone who wants to put on their preferred background sound on the commute and carve out a moment that's just theirs - People who want to roll their own ambient mix from binaural + nature layers ### Ads and Remove Ads - The free tier shows one AdMob banner at the bottom plus a short app-open ad on launch - If the ads disrupt your rest, tap Settings → Premium → **Remove Ads `$2.99`** for a one-time purchase that removes both forever (restored across devices on the same Apple ID) ### Your data stays on your device - Almost no personal data is collected.
