Battery Orbit keeps a plugged-in MacBook between limits you choose (20–90% by default): it charges to the top, runs on battery to the bottom with the cable still in, and repeats. Three modes (Custom Orbit, Natural Flow, Desk Hold), Charge to 100% once for travel days, calibration you start yourself to keep the % honest, and Insights showing time in range day by day. Pause gives normal charging back instantly. One-time price, no account, no subscription.
