Cleaning, laundry, dishes, errands, work. When everything needs doing at once, tell What First what is on your list. AI identifies the tasks in your sentences and suggests a numbered order. Start one task at a time. There are no timetables or timers. Each request is ordered independently. Entering new input clears the previous result. Results are not restored when you reopen the app. You can enter more than five tasks. You can also enter tasks by voice. On supported devices and languages, speech is converted to text on your iPhone. Check and edit the recognized text before ordering your tasks. Audio recordings are not saved or sent to the server. With your new consent to Google Gemini, only your current input is sent through the server to Google Gemini. After you agree, AI stays on by default. You can turn it off or allow it again in Privacy & AI. Existing Groq consent does not authorize sending to Gemini. The app is free. On-device basic rules take over if AI is unavailable or the operating budget or abuse-prevention limits are reached. Basic rules are also available in regions where Google Gemini is not supported and work without an internet connection. The update supports all 50 App Store metadata localizations with 47 interface locales. It follows your iPhone or per-app language, with English for unsupported languages. Language is not determined by the download country. Tasks retain your input language. Simple lists can be processed on-device; complex natural-language recognition varies by language. A personal task-ordering tool for adults aged 18 or older. AI and basic-rule suggestions are for reference. Unfamiliar or ambiguous expressions may not be recognized.
