Catch a thought on your Apple Watch. Find it when you need it. VoxWhisper is a quiet place for the idea on a walk, a shopping list, or the next thing you want to remember. Dictate a text note, search your saved notes, or record a voice memo with Pro. On compatible iPhones running iOS 26 or later, Pro turns Watch voice memos into searchable text using on-device speech recognition. Copy the transcript or save it as a note. Transcription requires speech recognition permission and a supported language; a model download may be needed. ON YOUR IPHONE • Read every note in a calm list, grouped by day, with search. • Write or dictate a note on iPhone; it reaches your watch through iCloud. • Say “Note in VoxWhisper” to Siri on your iPhone or your watch. • See your capture rhythm for the last 14 days. • Export your notes, or send one to Neuma, our second-brain app. • With Pro, voice memos recorded on your watch are copied to your iPhone to play and share. CAPTURE FROM YOUR WRIST • Open dictation from the Capture complication. • Save a note with Siri or a Shortcut. On Apple Watch Ultra, assign a compatible Shortcut to the Action button. • Get a haptic confirmation after a note is saved. • Use watchOS text input and the dictation languages supported by your watch. FIND AND USE YOUR NOTES • Search the notes available in your history by a word or phrase. • Read notes in order, with your newest thoughts first. • Share a text note through the watch's available sharing options. • Use the “Get latest note” Shortcuts action in your own workflows. • Confirm before deleting a note. YOUR NOTES, ON YOUR WATCH Your full text is saved locally. Reaching an iCloud sync limit does not trim your local archive. Text notes can sync through your own iCloud account; the app explains when some notes cannot sync. iCloud sync is limited and is not a complete archive backup. Audio memos never go to iCloud: they stay on the watch and, with the iPhone app, are copied directly to your iPhone. FREE AND PRO Dictation, Siri and Shortcuts, complications, text sharing, iCloud sync and access to your 25 most recent notes are free. Search covers the notes available in your plan. Older notes remain stored locally. VoxWhisper Pro unlocks your full note history and recording and playback of voice memos. When you reach 50 recordings or 100 MB, choose which recordings to delete before starting another. Recording also requires available device storage. The app does not automatically remove older recordings. Pro is an auto-renewable monthly or yearly subscription. Price and billing period are shown before purchase. Manage or cancel your subscription in your Apple Account settings. Eligible customers who originally purchased the paid app retain Pro at no extra charge. Made for Apple Watch running watchOS 10 or later, with a companion app for iPhone (iOS 17 or later). No separate account with us, ads, analytics SDKs or developer-operated transcription service. Dictation is provided by watchOS. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://berkemd.github.io/wristsuite/voxwhisper/privacy.html
