Step Lynx is a clean, focused step counter and activity tracker that lives where you actually look — your Lock Screen, your Home Screen, and your Apple Watch. No dashboards to wade through. Just clear progress, real streaks, and goals you can actually feel yourself moving toward. WHAT YOU GET • Live step count, distance, flights climbed, and active calories pulled straight from Apple Health. • Goal rings for every metric. Enable the ones you care about, hide the ones you don't. • Lock Screen widgets so your progress is always one glance away. • Home Screen widgets in every common size, from a single number to a full activity ring layout. • Apple Watch app and complications that mirror your iPhone, with goals that sync automatically. • Beautiful trends view so you can see your week, month, and lifetime at a glance. STREAKS THAT MEAN SOMETHING • Daily goal streaks for steps, distance, flights, and active calories — each one tracked separately. • Best streak protection so a single missed day or a metric you turn off can never erase a personal record. • A growing badge collection for first miles, big-step days, big stair days, big burn days, week-long streaks on every metric, and the rare "Triple Threat" days where you hit steps, distance, and flights all at once. CELEBRATIONS YOU'LL ACTUALLY NOTICE • Crisp haptic feedback every time you cross a goal. • A bigger "All Goals Crushed" celebration with a stronger haptic on days you sweep every enabled goal. • A clean badge detail view that explains what each award means and shows you exactly how close you are to the next one. NUDGES, NOT NOISE • Optional daily check-in: pick any time of day and get one friendly push with your live progress. The message adapts to where you actually are — gentle on quiet mornings, motivating on near-misses, congratulatory on early sweeps. • Goal-met notifications fire only once per day per metric, so you never get spammed. • All notifications are off by default. You decide when we speak up. PRIVACY • Health data stays on your device. Step Lynx reads from Apple Health, never sends your data to a server, and has no third-party analytics. • No account required. Open the app, grant Health permission, done. WHAT'S FREE AND WHAT'S PRO The core experience — live counts, goal rings, basic widgets, daily streaks, and the milestone badges most people care about — is free forever. Step Lynx Pro unlocks the full badge collection (week-long streaks on every metric, the rare "Triple Threat", deeper milestones), advanced widgets, and the lifetime stats view. One-time purchase, no subscription required for the core upgrade. KEEP MOVING Whether you're chasing a 30-day streak, climbing more flights than you did last month, or just trying to stand up more, Step Lynx makes it easy to see where you are and feel good about getting there. Thanks for using Step Lynx.
