MergeKey — the first keyboard that hides the keys you don't need. As you type, MergeKey dynamically removes impossible letters and expands the remaining keys, giving you bigger tap targets and fewer typos. It's like autocomplete, but visual — you see your options shrink in real time. MERGE MODE — UNIQUE TO MERGEKEY - Keys that can't continue your word disappear instantly - Remaining keys grow to fill the space — bigger keys, fewer mistakes - Learns new words you teach it - Toggle Merge Mode off if you prefer just the disappearing keys without resizing 20 LANGUAGES English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Greek, Turkish, Russian, Ukrainian, Indonesian, Vietnamese, Swedish, Finnish, Danish, Norwegian, Romanian and Hungarian — each with native prediction and accented character variants. English (US/GB) and Portuguese (BR/PT) with correct regional dictionaries. SMART FEATURES - Prediction bar with word suggestions - Long-press for accented letters and symbols - Character preview bubble on key tap - Optional dedicated number row - Double-tap shift for caps lock - Backspace hold-to-accelerate (characters, then words) CUSTOMIZABLE STYLE - 4 keyboard styles: iOS 26 Liquid Glass, Classic, Flat, Flat Glass - Custom key fill and border colors - Transparency slider for key fill opacity - Spacebar icon options - Animation speed control BUILT FOR LEARNERS - Swipe up to teach MergeKey a new word - Swipe down for continuous mode (all keys visible) - Swipe left to delete whole words - Swipe right to repeat the last word - Built-in typing game to practice in any language PRIVACY FIRST MergeKey does not collect or transmit your typing data. Everything stays on your device. MergeKey never connects to the internet. The only network activity is the App Store handling the optional tips – that's why iOS shows a Mobile Data switch for MergeKey.
ICS Toolkit

Create events. Edit ICS files. Export calendars. ICS Toolkit brings your calendar tools together on iPhone and iPad. Start with five clear actions: Create Events, Edit Events, Export Calendars, Import Calendars, and Server Mode. Choose a calendar on your device and save its synced events together in one ICS file. Repeating events keep their repeat rules and edited occurrences. Save the file to Files or share it with another app. Read-only calendars are supported too. Build events with notes, locations, links, time zones, reminders, and attachments. Set daily, weekly, monthly, or yearly repeats. Add an organizer and attendees to create meeting invitations for compatible calendar and email apps. Open an existing ICS file and choose the event you want to edit, even when the file contains multiple events. Search by title or location, then save the edited event as a separate file. Import events from single-event or multi-event ICS files into a device calendar. Review an event before saving or sharing it. Check its details, see compatibility messages, and inspect the generated ICS text. Autosaved drafts and reusable templates help you prepare events you create often. Use Server Mode to connect compatible CalDAV calendar apps to selected calendars on your iPhone or iPad. It works over a trusted local network while ICS Toolkit stays open and active. ICS files work with Apple Calendar, Google Calendar, Microsoft Outlook, and other compatible apps. Supported details vary by destination. Some information, including attendees and embedded attachments, needs to be shared as an ICS file instead of added directly to Calendar. Calendar export includes only events synced to your device. Apple's calendar access does not provide event attachments or all deleted repeating-event exceptions; deleted occurrences may reappear after import. No account is required. Your drafts and templates are saved on your device.
