Litiva vs Snubline

Litiva brings your habits, reminders, journal and focus sessions together in one place. Build small routines for mornings, work, movement, hydration, medicine or time for yourself. TODAY, AT A GLANCE See your plan and daily progress. Check off a habit with one tap, undo a mistake, or switch to a compact checklist. Open a habit's details to review its calendar, add a note or record a missed check-in. A ROUTINE THAT FITS Choose daily, weekday, weekend or custom repeat days. Set a reminder time, add an early alert, or keep a habit untimed. Create your own categories and pause or archive habits while keeping their history. ON YOUR WRIST The Apple Watch companion shows today's habits and progress. Complete or undo a check-in from your watch. Offline actions queue and sync with your paired iPhone when a connection is available. A paired iPhone is required. A JOURNAL TO RETURN TO Keep thoughts, moods and tags in a familiar timeline. Search past entries, save a quick mood check-in and return to an unfinished draft. On supported devices, preview, apply or undo writing suggestions from on-device Apple Intelligence. FOCUS, THEN CARRY ON Start a short focus session from a habit. Pause, resume or return after leaving the app. Follow your timer through Live Activities and Dynamic Island on supported systems. YOUR RECORDS, IN YOUR HANDS Back up saved habits, categories, check-ins and journals with optional password protection. Export check-in history as CSV. Preview a backup before merging or replacing records, and undo your most recent restore. SEE YOUR PROGRESS Review daily completion, consistency and your yearly calendar. Completed actions help your yearly tree grow. BUILT FOR YOUR DEVICES • iPhone and iPad layouts, light and dark appearances • Seven habit illustrations and small, easy-to-reach controls • Interactive widgets, Siri, Shortcuts and Spotlight • Notification actions and Control Center controls on supported systems • Private iCloud sync between iPhone and iPad • 50 app languages and regional variants Apple Health is optional. With your permission, completed hydration and mindfulness sessions can be saved to Apple Health. Some system features require a compatible device, software version and permission; writing assistance requires supported Apple Intelligence. No ads, tracking or subscriptions. No separate Litiva account is needed.

Explore rigging physics with an educational model. Snubline uses assumed inputs to illustrate equations and compare numerical values. It has no independent professional validation or complete rope calibration dataset. It is not a professional planning or load-safety assessment tool. Do not use its results to select equipment, determine actual loads, plan a cut, or decide whether an operation may proceed. Obtain qualified on-site assessment independently of the app. THE EDUCATIONAL MODEL - Compare snubbed and constant-slip let-run assumptions using a closed-form spring-mass equation. - Inspect peak tension, dynamic load factor, stretch, block force and device force, with equation details. - The rope conversion factor 0.075 and example moduli are provisional teaching values. - The 75%-125% display range is illustrative, not a validated error bound or confidence interval. Actual loads may fall outside it. - Fall factors above 2 are limited to 2, with a visible warning; the result no longer represents the full entered drop. NUMERICAL FORCE-VERSUS-RATING COMPARISONS Enter your own tag ratings and design factors. Within WLL, Approaching WLL, Exceeds WLL and Exceeds MBS describe numerical comparisons of model values only. They do not approve equipment or operations. EXAMPLES AND DOCUMENTS Estimate log weights from idealized geometry and species density, with estimate labels carried into comparisons. Save scenarios, gear records and jobs. Compare scenarios and share educational comparison PDFs or images. Existing frozen snapshots remain stored; documents rendered by this version carry the current educational restriction. TRANSPARENCY The free model page explains equations, provisional calibration, formula-test limitations and omitted effects including swing, tree flex, rope heating, friction variation and fatigue. Climbing, life support and crane operations are outside the model. YOUR DATA Records remain on your device. No account or cloud sync. If saved records cannot be opened, recording is paused and existing database and attachment files are kept. FREE Both model modes, equation details, the weight estimator, the model page, three Gear Locker items and one job. PRO Unlimited Gear Locker items and jobs, what-if comparisons, PDFs and share cards, custom rope profiles and widgets. Pro does not change model validity or calculation correctness. Choose a one-time Lifetime purchase or annual subscription. Existing monthly subscribers retain access while their Apple-verified entitlement is active. Any trial applies only when Apple confirms eligibility; the purchase screen shows the actual price and offer. Subscriptions renew unless cancelled in Apple subscription settings before renewal.
