Best with Apple Watch · Works with iPhone alone
For everyone who forgets things. Your Apple Watch, or just your iPhone, listens during the hours you choose, and what was said is kept as text on your iPhone. Ask about your day any time, and get the exact words back.
How it works
Your Apple Watch listens during the hours you choose, even with your iPhone left behind. One tap in the morning, and it stops on its own. Our in-house ultra-light speech model runs right on the watch and keeps only the moments when someone is talking.
Your iPhone turns the speech into text on the device, keeps no audio, and picks out the to-dos, deadlines and meetings. It can also tell what you said from what others said.
Your memories stay on your iPhone, and answers use Apple’s on-device model. You can choose your own cloud API later; nothing is sent until you allow it.
Devices
Apple Watch listens on its own, all day. What it hears waits on the watch and goes to your iPhone every two hours, and if your iPhone isn’t around, it catches up as soon as the two reconnect, say when you get home in the evening. Your iPhone never has to stay connected.
On your wrist all day, with no phone needed.
No Apple Watch? Your iPhone can listen on its own.
One timeline for the day. What both heard shows once, and if the watch stops, your iPhone can take over.
It starts with Apple Watch and iPhone: every device that listens adds to one memory.
Battery
A professional-grade, ultra-light speech model built in-house: just 2,561 parameters, running on our own accelerated inference kernels and making a call every tenth of a second, right on the watch.
Only speech is kept. Silence, keyboards and fans are filtered out before they cost any battery. Everything from the architecture to the kernels was designed for the watch, drawing on our doctoral research in AI acceleration.

Voices
Read five short cards once, about a minute, and everything you say is marked Me. Everyone else in the conversation gets a number of their own, Other 1, Other 2 and on, so your promises and the ones made to you never get mixed up.
Optional and off by default. Speed based on internal testing on iPhone 17 Pro Max.
Languages
Pick up to three working languages. DayRecall detects every switch and transcribes each part in the language it was spoken in. Lines in the other languages can then be translated into yours.
Multilingual transcription is an advanced setting, off by default. Speed based on internal testing on iPhone 17 Pro Max. The app itself comes in 13 languages.
Features
Promises, deadlines and meetings are picked out of your day. Nothing reaches your calendar or Reminders until you say yes.
What did Sam promise? When is the report due? Every answer shows where it came from, down to the line that was said.
See a day as a timeline, flip back through past days, and search everything you’ve heard.
Each week, the deadlines and promises ahead in one place. You pick what goes on your calendar.
See where each conversation happened on a map of your day. Off until you turn it on.
For a deeper look, send a day’s transcript to the AI app you use, as a text file, only when you choose.
Privacy
What’s said is turned into text on your iPhone. The audio is cleared automatically once it’s transcribed, and isn’t kept.
There’s nothing to sign up for, and we don’t run servers that see your day.
Answers use Apple’s on-device model. Handing a day to an AI app, or using your own cloud API, happens only when you allow it.
DayRecall is an AI memory app for Apple Watch and iPhone, made for people who forget things. During the hours you choose, it listens, keeps what was said as text on your iPhone, and answers questions about your day with the exact words and where they came from.
No. DayRecall works best with Apple Watch, and your iPhone can also listen on its own. When both listen, your day is one timeline, and what both heard is shown once.
No. What’s said is turned into text on your iPhone, and the audio is cleared automatically once it’s transcribed. Only the text is kept.
On your iPhone, and in its backup if you use one. There’s no account and no DayRecall server, so we can’t see it. Answers use Apple’s on-device model, and nothing leaves your iPhone unless you choose to use your own cloud API or hand a day to an AI app.
AI memory for your whole day.
