Build better habits, keep the streak alive, and finally stick to the routine you keep planning. HabitKeep turns what you mean to do into a daily list you can actually finish - on your iPhone, your Home Screen, and your Apple Watch. TRACK ANY KIND OF HABIT Simple check-offs, step-by-step counts, custom values (glasses of water, pages read, minutes practiced), or a built-in timer and stopwatch for time-based habits. A Live Activity keeps a running timer on your Lock Screen. A SCHEDULE THAT FITS REAL LIFE Repeat every day, on chosen weekdays, every few days, or a set number of times per week or month. Schedule goal changes ahead of time and keep the full history. Going away? Vacation mode pauses habits for a date range instead of breaking your streak. STREAKS, STATS AND INSIGHTS Current and longest streaks, completion rate, an adaptive trend chart, a weekday heatmap, category and habit breakdowns, and a full-year contribution grid. Step back through past weeks, months and years, or compare two periods side by side. REMINDERS THAT REACH YOU Reminders per habit or per category, plus a daily check-in nudge. Mirror them into the Calendar app so your habits sit alongside everything else in your day. APPLE HEALTH DOES THE LOGGING Steps, workouts, sleep, water and 58 other metrics can fill your habits in by themselves, so movement goals tick off without you touching the app. WIDGETS, APPLE WATCH AND SIRI 14 Home Screen widget styles, many with tap-to-check-off. A full Apple Watch app with its own habit list, logging, and mini contribution grid. Ask Siri or run a Shortcut to log a habit or start and pause a timer, hands-free. ACHIEVEMENTS AND YOUR YEAR, WRAPPED Unlock 37 achievement badges as momentum builds, then close out the year with a Wrapped-style recap and a share card worth posting. MAKE IT YOURS - 37 languages - custom accent color - light or dark theme - categories with own icons and colors - four habit row styles: grid, bars, line or progress YOUR DATA STAYS YOURS iCloud keeps every device in step, and you can switch it off. Export and import everything as JSON, or start over with Fresh Start whenever you like. HABITKEEP PRO HabitKeep is a fully extended habit tracking app. Pro lifts the habit limit and unlocks Apple Health sync, Calendar sync, advanced statistics, every widget, and your yearly Wrapped - and removes ads. Available monthly, yearly, or as a one-time lifetime purchase. Start with one habit today, and let the streak do the rest.

PreviewMD is a fast, native editor and viewer for Markdown on iPad and iPhone — the same rendering as the Mac app, free on both. Open any .md file from Files or iCloud Drive, or start a new document right in the built-in browser. FOUR WAYS TO WORK • Preview — a clean reading view • Split — live preview beside the Markdown source, side by side on iPad and stacked on iPhone • Source — the Markdown alone, full width • Diff — see exactly what you've changed since you opened the file, word by word BEAUTIFUL RENDERING • GitHub-flavored Markdown: tables, task lists, footnotes and strikethrough • Syntax highlighting for almost two hundred languages • Math typesetting with KaTeX — $inline$ and $$display$$ • Diagrams with Mermaid — flowcharts, sequence, class, state, pie and gantt • GitHub-style alert callouts (> [!NOTE], [!WARNING], …) and emoji • Automatic light and dark mode WRITING ON A TOUCHSCREEN A formatting bar sits above the keyboard for bold, italic, inline code, headings, quotes, lists and links. With a hardware keyboard the same actions have shortcuts. YOUR DOCUMENTS, YOUR IMAGES Works with the Files app and iCloud Drive — documents open in place and save as you type, with no Save button to remember. Local images referenced by your document display right in the preview. EXPORT, SHARE & PRINT Export self-contained HTML or clean light-mode PDF straight to the share sheet, or print with proper pagination. QUICK LOOK Markdown files preview with PreviewMD's renderer in the Files app too. ONE APP EVERYWHERE Free on Mac as well — including Quick Look previews and thumbnails in Finder. Requires iOS/iPadOS 17 or later.
