Input Enhancer — put your own words in the keyboard bar Your keyboard doesn't know the words you actually use: specialized terms, product names, abbreviations, place names, industry jargon. So you type them piece by piece and hunt through pages of candidates. Input Enhancer writes your word list into Contacts as contact names. Apple's keyboard prioritizes contact names as candidates, so your entries show up right in the candidate bar — one tap inserts them. No third-party keyboard, no keyboard permission, no typing data leaving your device. HOW IT WORKS Contact name = entry. Apply a dictionary, wait for the system index to update (usually a few minutes), then start typing and tap the entry in the candidate bar. BUILT-IN DICTIONARIES - 6 dictionaries in 3 categories — 20,500+ entries in total - Free: US Cities - Paid: Foreign Trade Vocabulary, Financial Accounting, Finance Terms, Insurance Vocabulary, Computer Terminology - Browse by category, search, and apply a whole dictionary with one tap - Applied dictionaries stay in sync and can be re-applied or removed at any time YOUR OWN WORD LISTS - Import a .txt file or paste text — on-device processing extracts entries and builds a dictionary automatically - Add custom entries one by one - Export applied dictionaries as .txt to back up or share (Import, custom entries and export are included with the subscription.) CONTACTS TOOLKIT - Merge duplicate contacts, or batch add notes, name prefixes, company info and phone prefixes - Organize your own contacts into a group that stays separate from dictionary groups - One-tap undo for the last operation, with a safety check before rollback PRIVACY AND SECURITY - Everything stays on your device: entries live in Contacts, dictionary files are encrypted, and nothing is uploaded - No account, no ads, no tracking, no analytics - Contacts access is used only to write entry contacts — your Contacts are never uploaded FREE AND PAID - Free: free dictionaries work immediately, with apply, manage and export - One-time purchase: unlock all paid dictionaries, including future additions (price varies by region) - Subscription: unlock import, custom entries and export (price varies by region; auto-renewing; manage or cancel anytime in your Apple ID settings) GETTING STARTED 1. Open Dictionary Center and tap Apply on a dictionary 2. Wait for the system index to take effect (a few minutes), then try typing 3. If candidates don't show up, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Keyboard Dictionary, then try again This app works with Apple's built-in keyboard. It does not install or require any third-party keyboard. Terms of Use:https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: Rectfly at none against 输入法增强's 1. Rectfly also leads on update cadence (every 2 days vs every 2 weeks). 输入法增强's advantage is iOS requirement (15.0 vs 26.0). On price, ads and device support there is nothing between them.
