| Sleepwave | AVA | |
|---|---|---|
| Tracking method | Sonar, no wearable needed | None |
| Wake-up | Smart window | Spoken briefing |
You set a time, pick a character voice, and say what you are working toward. Each morning AVA writes a fresh short script from your goals — and your calendar and the weather if you connect them — then speaks it in that voice over a music bed while the words appear on screen. It fires over the lock screen like a normal alarm.
The free tier is 7 AI wake-ups a month. After that the alarm still rings on a basic tone, and the AI briefing is the part you subscribe for.
No. Just the phone.
