Hush Habit is a private, local-first field journal for observing recurring routines. Define one behavior, write a working hypothesis, choose an interruption plan, and record what actually happened without streak pressure or an opaque score. PROTOCOL LAB Create a 3-to-30-day observation window with a baseline estimate, planned pause, replacement action, and reversible environment edit. Keep one protocol active at a time, review progress, and preserve completed protocols in an archive. CUE ATLAS Inspect direct counts from your saved observations: cue labels, time bands, outcomes, replacement use, observed days, and the median of urge values you entered. Every summary exposes its denominator and calculation boundary. SEARCHABLE JOURNAL Filter observations by cue or outcome, search notes and protocol names, edit records, and remove entries you no longer want. Sample records make the complete workflow reviewable from the first launch and disappear when you save your own work. SOURCE-LINKED PRACTICE DECK Browse 12 illustrated field exercises for cue snapshots, if-then plans, short pauses, replacement menus, environment edits, factual review, and bounded protocols. Five primary literature notes link directly to DOI source pages. PORTABLE, PRIVATE RECORDS Export a PDF field report, CSV observation rows, plain-text summary, or JSON workspace backup. Restore a backup by merge or replace. Optional local reminders are requested only after you enable them. No account, advertising, tracking, third-party analytics SDK, subscription, or developer-operated backend is required. Records stay in the app's local container unless you intentionally share an export. Hush Habit is a personal observation journal. It does not diagnose, prevent, or treat a medical or mental-health condition. ## Version history (last 5 releases) ### 2.4 — 2026-08-23 Hush Habit 2.4 is a ground-up rebuild around transparent, private behavior experiments. - Create bounded protocols with a hypothesis, baseline, pause, replacement, and environment edit. - Review direct counts and visible denominators in the new Cue Atlas. - Search, filter, edit, and delete records in the redesigned journal. - Browse 12 illustrated practice cards tied to five primary DOI sources. - Export PDF, CSV, text, and JSON records, then merge or replace a restored backup. - Use a native iPad sidebar and a focused iPhone tab layout. - Enable an optional local reminder only when you choose. No account, subscription, analytics, tracking, or remote profile was added. ### 2.3 — 2026-08-13 Hush Habit 2.3 adds a complete Experiment Studio for running one focused personal trial at a time. - Choose a focus, replacement action, and 3- to 30-day duration. - Start a run, follow day-by-day progress, and open a check-in directly from the experiment. - Use a clearer five-tab layout on iPhone and iPad. - Reach PDF, text, CSV, backup, reminder, privacy, and source tools from Toolkit. - Keep reminders visibly off when notification access is unavailable. - Review tightened educational wording and direct source links inside the app. Everything remains local unless you intentionally share an export or backup. ### 2.2 — 2026-08-01 ExperimentStudio: Baseline windows, replacement efficacy, urge practice, and lapse recovery. - Choose one behavior, baseline window, and humane success definition - Record trigger context and urge intensity without moral scoring - Practice one replacement or urge-surf routine during the experiment - Compare event frequency, recovery, context, and small-sample uncertainty - Save a private weekly decision and preserve repair after lapses ### 2.1 — 2026-06-28 Hush Habit 2.1 adds a deeper practice layer for people reducing scrolling, spending, snacking, late nights, or other personal habits. Plan Lab now builds a seven-day if-then experiment from your own check-ins. It looks at the strongest current pattern, suggests a risk window, offers a replacement action, and writes a simple script you can try for the next week. The new offline practice deck includes 12 visual cards for cue audits, implementation intentions, friction setup, urge waves, long-exhale breathing, HALT checks, slip repair, self-monitoring, and weekly review. Source links are included in the app so the basis for the wording is easy to inspect. Exports now include the current practice experiment alongside streaks, patterns, backup, CSV, and PDF reflection tools. As always, everything stays on your device. No account, no ads, no in-app purchases, and no tracking. Hush Habit is a self-reflection utility, not medical or mental-health treatment. ### 2.0.1 — 2026-06-26 This update focuses on behind-the-scenes stability and performance improvements, plus small refinements to keep things running smoothly. As always, everything stays on your device — no account, no ads, no in-app purchases, and no tracking. Hush Habit is a self-reflection utility, not medical or mental-health treatment. ## More apps by Robert Corbin - [Daily Word Journey](https://appshunter.io/ios/app/daily-word-journey/id6761548266) - [Hush Secret Text](https://appshunter.io/ios/app/hush-secret-text/id6761658175) - [Renew Guard](https://appshunter.io/ios/app/renew-guard/id6761755447) - [Receipt to PDF](https://appshunter.io/ios/app/receipt-to-pdf/id6761782025) - [Route Your Pay](https://appshunter.io/ios/app/route-your-pay/id6761783719) - [Tip Arbiter](https://appshunter.io/ios/app/tip-arbiter/id6761786879) All apps by Robert Corbin: https://appshunter.io/developer/1890247992 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
