Understand your signals. Find your next step. Nostresso brings your stress, recovery, sleep and energy estimates together in a calm, clear view. Compare recorded days, see gaps honestly, and build small goals from your own patterns. Ask the private assistant about your readings, trends or goals. Compatible iPhones use Apple's on-device model. Type or use native local dictation, with optional spoken replies. Siri and Shortcuts open your screens and read available summaries. Connect Screen Time where Apple permits access to compare daily iPhone use with recorded stress. This optional comparison stays on device and does not imply that screen use causes stress. Works with Apple Health and Apple Watch data. Apple Intelligence, dictation and Screen Time depend on device, language, region and system availability. Missing readings stay unknown. Scores are wellness estimates, not diagnoses or medical advice.

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. โ 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. โ 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. โ 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. โ 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. โ 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.

Verdict
The clearest difference is in-app purchases: Nostresso at none against Stral's 2. Nostresso also leads on update cadence (every 4 days vs every 3 weeks). Stral's advantage is iOS requirement (18.6 vs 26.0). On price, ads and device support there is nothing between them.
