PDFCrab lets you edit PDF files directly on your iPhone — no cloud, no subscriptions, no sign-in required. All processing happens locally on your device. -Forms Fill interactive PDF form fields directly in the app, then export the completed form. -Search in your PDF Search for any word or phrase across your document and replace it in place — the surrounding text keeps its layout. -Highlight text Highlight any passage of text to make it stand out. Choose the highlight color and opacity, then move or remove a highlight at any time. -Smarter text editing Related text now groups into sections, so you can select and edit a whole block at once instead of line by line. -OCR Scan a photo or PDF of a document and PDFCrab recognizes the text on-device, turning it into real, selectable, editable PDF text instead of a flat image. Review and correct recognized text, then save as separate files or merged into one PDF. -Cyrillic, Chinese, Japanese & Korean support Editing text and recognizing text via OCR now correctly handles Cyrillic and CJK scripts, not just Latin — the right font is embedded automatically based on what the text actually contains. -Edit text Tap any text in your PDF to select it, then drag it to a new position or update its content. Choose from 9 bundled fonts or keep the original. Preview font and size live before saving. -Edit images Move, resize, or remove images embedded in your PDF. Drag any corner or edge handle to resize precisely, or pick a quick percentage preset. -Page Tools Add page numbers in the position you choose, rotate any page, and switch between Standard and Letter page sizes — with a one-tap way back to the original size. -Manage Pages Browse a thumbnail grid of all pages to delete the ones you don't need — now extended with Reorder: drag pages into a new order and save when you're ready. -Export Turn any PDF into a TXT file, an audio narration, page images, a Word document, or a PowerPoint — directly on your device. -Password-protected PDFs Open, edit, and save encrypted PDFs. Add, remove, or change passwords. View encryption algorithm, key length, and per-flag permissions. Your password never leaves your device. -Annotate Draw, highlight, and add freehand annotations using Apple Pencil or your finger. -Privacy first PDFCrab never uploads your files. Everything stays on your device.

Make today count with Habit Tracker: Planner Routine, a calm daily habit tracker for building routines, reaching goals, protecting focus time, and understanding your progress. Create habits for anything you want to build or quit. Track simple checkmarks, counts, durations, or custom values. Plan routines by day, category, time of day, start date, end date, and custom weekly schedules. See progress without digging. Your Today view shows daily goals, completion rate, category filters, and quick logging in one clean dashboard. Add notes after important completions so your habit history captures the reason behind the result, not just the checkmark. Works with Apple Health. Link supported habits and your progress fills in automatically from the Health app: steps, activity minutes, active energy, sleep, water, heart rate variability, and mindfulness minutes. Values you log in Habit Tracker can be saved back to Apple Health too. Health data only syncs after you grant permission, and sync is included for free. Turn consistency into insight with stats, streaks, heatmaps, and reports. Review weekly, monthly, and yearly progress, spot your best days, compare sleep and hydration trends, and connect mood logs with habit completion to learn what helps your days feel better. Protect your streaks on hard days. Every week of completed days banks a Streak Shield that is spent automatically to save a streak when you miss a day. Skip a day on purpose without losing momentum, or turn on Vacation Mode so nothing breaks while you are away. Get a nudge only when it matters. Smart streak risk alerts warn you in the evening before a streak ends, and an optional evening check-in lists whatever is still open for the day. Both stay quiet when everything is already done. Stay focused with a built-in focus timer. Run timed sessions, save deep work minutes automatically, and attach focus time to any duration habit. Keep habits close with Home Screen and Lock Screen widgets. Check progress, quick-log routines, and keep weekly, monthly, and yearly report widgets visible throughout the day. Built for everyday use: - Build and quit habits - Apple Health sync for steps, sleep, water, mindfulness, and more - Daily, weekday, weekend, and custom schedules - Checkmark, count, duration, and value tracking - Categories for routine, health, fitness, mind, work, and more - Habit templates for walking, water, sleep, meditation, reading, workouts, deep work, and more - Streaks, totals, heatmaps, and completion rates - Streak Shields, Vacation Mode, and streak-safe skip days - Smart streak risk alerts and an evening check-in - Mood logging and daily rewards - Focus sessions with automatic habit logging - Time and location reminders - Widgets for today, progress, and reports - Theme colors, with alternate app icons available in Premium - App Lock, export, and import tools available in Premium Habit Tracker Premium is an optional one-time purchase that unlocks unlimited habits, extra reminders, advanced reports, all widget habits, App Lock, backup/import, and alternate app icons.
