BAI Study
Read full descriptionHide full description
BAI is a research application for enrolled study participants. BAI helps you see your workload and set boundaries around it. It reads the calendar already on your phone to show how full each day really is, and pairs with how you say you are feeling — so the picture is both what you agreed to and how it landed. WHAT IT DOES • Broadcast where you stand — Available, Busy, Heads-down, Stretched or Unavailable • See each day's load measured against your focus hours, not the clock • Check in with a mood, and get a status that matches how you actually feel • Move between Work and Life automatically, by schedule or by place • Be told when a day is booked past what it holds YOUR DATA STAYS ON YOUR PHONE Everything BAI records — your mode, status, mood check-ins, calendar readings, places and history — is stored on the device and never uploaded. The only thing sent anywhere is the phone number you sign in with, checked against the study roster. Taking part is voluntary, and you may withdraw at any time

Verdict
The clearest difference is update cadence: BAI Study at every 2 days against Lingu's monthly. On price, ads, in-app purchases and device support there is nothing between them.
