Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
A big design refresh and smarter logging.
• A cleaner, faster look everywhere - live dashboards for Training, Body, Sleep, Nutrition and Wellness with sparkline trends; a signature glow marks whatever's active right now; smoother scrolling on every page.
• Smarter food logging - readable macros on every entry with a composition stripe, and a new portion slider: drag the calories and protein, carbs and fat scale with it. Scale half a portion or a 10x meal-prep batch in one gesture.
• Rest days got a glow-up - a night-sky recovery hero with your next workout on it, instead of an empty screen.
• The workout review, rebuilt - headline stats on the hero, honest detail metrics, and a per-exercise share bar showing where the session's volume went.
• Your plan, honestly - routine day cards now show the programmed weight AND your last lifted weight, flagged when they disagree so a stale plan can't catch you off guard.
• Rebuilt calorie targets - your daily goal is your own chosen range with a clear in-range / under / over verdict. Exercise no longer secretly inflates your target.
• Late-night logging finally makes sense - food logged after midnight counts toward the right training day, marked with a moon.
• Tailored exercise alternatives - ranked, injury- and equipment-aware swaps in the swap sheet, editor, and live workout.
• Dozens more: cross-workout weight sync, always-reachable supplements log, lock-screen widgets, cleaner AI pairing with a simpler QR, and countless fixes.
