It's not your fault your habits don't stick. It's the app's fault. Miss just one day and a 100-day streak resets to zero. Traveling? Sick? Too bad. That's how every other habit app works. Stral is different. ◆ Streak Recovery -- Break it, then bring it back If your streak breaks, just start again the next day and you'll enter "recovery mode." Complete a short recovery period and your full streak is restored. No more starting over from zero. ◆ Habit Lifecycle -- Take a break without losing progress Pause: Set a pause period for travel or illness. Your streak stays safe. Exclusion days: Need to skip just today? No problem. It won't count against you. End & Resume: Archive completed habits. Your records are kept forever. Features no other habit app offers. Only in Stral. ◆ All of this is free Up to 6 habits 4 tracking modes (Check / Negative / Count / Timer) Streak recovery Habit lifecycle management (Pause / Exclusion days / End / Resume) Apple Health auto-tracking (Steps, Exercise, Calories, Water, Sleep, Weight, Mindfulness, and 11 categories total) Apple Watch support Home screen widget iCloud sync Smart notifications 3 themes Features that other apps charge for are completely free in Stral. ◆ 4 modes for any habit Check: Did you read? Floss? Journal? One tap to record. Negative: Quit smoking, no drinking, skip the snacks. Days you didn't do it build your streak. Count: 8 glasses of water, 50 push-ups. Tap +1, auto-complete at your target. Timer: 10 min meditation, 15 min stretching. Built-in countdown timer. Works in the background. ◆ Automatic Apple Health integration Steps, exercise minutes, calories burned, water intake, sleep, weight, mindfulness, workouts, walking distance, swimming distance, stand hours. 11 categories of data are read automatically to complete your habits. Just exercise with your Apple Watch -- no need to even open the app. ◆ Go Pro and make it yours (just 2 cents a day) Unlimited habits 15 rich themes (the entire look and feel of the app changes) Unlimited motivation photos Pro isn't about unlocking features behind a paywall.

Zone 2 Training Coach answers one question every week: did you get your Zone 2 minutes? It reads your heart rate from Apple Watch, or another device that saves it to Apple Health, and counts every minute you spend in Zone 2, in workouts and outside them, like a brisk walk. You don't have to press start or log anything. Your weekly goal fills a ring on Home, and daily bars show how your week is going. WEEK-BY-WEEK PLANS 8 plans that build your Zone 2 minutes week by week, from a no-gym Walking Starter to the 3 Day Gym Plan for Fat Loss, the Fat-Burning 12-3-30 and Lift Heavy, Run Easy. Each day shows what to do: lift days exercise by exercise, Zone 2 days step by step with a starting incline, and one tap starts the session on your Apple Watch. The Walking Starter is free in full, and week 1 of every plan is free. ZONES THAT MATCH YOUR WATCH Zone 2 Training Coach uses the same heart rate zones as Apple's Workout app. On iOS 27 it reads your Watch's zones directly; on earlier iOS it estimates them the way Apple does. If you've had your zones tested, or your coach gave you numbers, enter your own. LIVE ON YOUR WRIST Start a Zone 2 workout on Apple Watch and get a big live heart rate, zone colors, a time-in-zone timer and a tap when you drift out of Zone 2. Your iPhone shows it live. Prefer Apple's Workout app? Send a Zone 2 workout there with a Zone 2 alert. TODAY A 24-hour heart rate and zone chart, your latest heart rate, and your Zone 2 minutes for the day, plus 7-day averages. CARDIO FITNESS See your VO2 max level for your age and sex, from Apple's Cardio Fitness estimate, compared with published reference data. IS MY ZONE 2 WORKING? Your Zone 2 minutes alongside your Cardio Fitness, resting heart rate and your speed at Zone 2 heart rate over time. RECOVERY A daily score from your HRV, resting heart rate and heart-rate recovery, compared with your own normal. LEARN Short, plain-English articles on Zone 2, heart rate zones and VO2 max. ZONE 2 PRO • Every week of all 8 training plans • Your next Cardio Fitness level, and a Zone 2 Coach that plans your week toward it around your schedule • Scheduled Zone 2 sessions with Apple Watch reminders • 3, 6 and 12-month progress • Full day-by-day history, 30 and 60-day averages, and 4 and 12-week trends • Custom weekly targets up to 600 minutes, and the Wednesday nudge • Apple Watch complication and home-screen widgets PRIVATE BY DESIGN No account. Your health data stays on your iPhone. Zone 2 Training Coach doesn't sell or share your health data. Works with the heart rate in Apple Health. Apple Watch gives the most complete picture, and heart rate from other devices that sync to Apple Health counts too, such as Fitbit, Garmin, Whoop, Polar and Coros. Some features need an Apple Watch: Cardio Fitness (VO2 max), the Watch app and its live Zone 2 workouts, and complications. Some features need newer software: reading your Watch's own zones needs iOS 27, and the coach's natural-language wording uses Apple Intelligence where available. Zone 2 Training Coach is for general fitness and is not a medical device. Talk to your doctor before starting a new exercise program.
