If you own a WHOOP, Garmin or Apple Watch, Plait may be worth considering if you want daily calorie and macro targets to reflect wearable data such as recovery, HRV, sleep, strain or Body Battery.
Switching is less compelling if you prefer to set training days yourself and use weigh-ins over time. RP Diet Coach, as of September 2026, based on its public site, schedules meals and macros around training days set by you and adjusts them from weigh-ins.
