HOW TO USE FLOW ALARM: 1) Place your Flow Dock across the room from your bed 2) Set your wake-up time in the app 3) When the alarm sounds, get out of bed and tap your iPhone on the Dock to dismiss it Flow Alarm tracks your sleep patterns and records your sleep sounds — including snoring and sleep talking — using your phone's mic so you can understand and improve your nightly rest. If you want to finally stop oversleeping and wake up on time every single day, Flow Alarm will get you there more reliably than any other alarm. We aren’t another gentle alarm app full of snooze buttons. We built a stupid-simple physical system that forces you to get up. You still have to do the work of getting out of bed, but we’ll give you the hardware and intelligent sleep tools you need to build a consistent wake-up habit and better rest for good.

Take a photo of your plate. Caly reads it and logs the calories, protein, carbs and fat — in seconds, without a search box. SNAP A MEAL Point the camera at your food. Caly recognises what is on the plate, estimates the portion, and writes it into your day. If something is off, tell it what changed and it corrects the whole meal. SCAN A BARCODE Point at a packaged product and Caly pulls the nutrition panel straight off the label — per portion, per pack, or per 100 g. Switch between them with one tap and every number follows. SAY IT INSTEAD "A bowl of porridge with blueberries." Say it out loud and Caly logs it. YOUR DAY AT A GLANCE Calories left, protein, carbs and fat, and the breakdown of every meal you logged. Widgets put the same numbers on your Home Screen and Lock Screen. APPLE HEALTH Caly reads your steps and your weight from Apple Health, and writes the weight you enter back, so you never type the same number twice. MORE THAN CALORIES Water. Weight history. Exercise. BMI. A daily streak. Save the foods and the meals you eat every week, and log them again with one tap. IN YOUR LANGUAGE English, French, German, Spanish, Italian and Portuguese.
