The day-by-day shape of a normal flu is right below, along with the signs that deserve a call to your doctor. BodyBuddy checks in by text every day until you're better.
Knowing which day you're on changes how the whole week feels.
Days 1 to 2
Fever, chills, and aches land within hours, and this is the most contagious stretch, so stay home.
Days 3 to 4
The fever peaks and starts to break while congestion and a dry cough take over. Fluids and rest are the whole job.
Days 5 to 7
The fever is gone and energy comes back in pieces. The cough usually outlasts everything else.
Week 2
A lingering cough and surprise tiredness are still normal. By day 14, most people feel like themselves.
Call your doctor if you notice any of these:
If you're pregnant, over 65, or managing a chronic condition, make that call earlier rather than later. Antiviral medication works best within the first 48 hours.
The days blur together when you're sick, which is exactly when it helps to have someone keeping count with you.
One text starts it, and the check-ins end when you're better.
Text BodyBuddy that you're sick
Tell it what day you're on and how you feel, in your own words.
It checks in every day
A morning text asks how you slept and where the fever is, then reads your day against the normal arc.
It ends when you're better
When your energy is back and the fever is a memory, the check-ins wind down with it.
If you or your kid got seen and came home with instructions, text BodyBuddy a photo of them. The medication timing and the stay-home guidance fold straight into your daily check-ins.

Common questions
The honest answers about flu recovery.
For most healthy adults, the flu lasts one to two weeks. Fever, chills, and body aches usually dominate days 1 through 3, the fever breaks around day 4 or 5, and energy starts returning around days 5 to 7. A lingering cough and tiredness into the second week are common and normal. If your fever is still going strong past day 5, or your symptoms improve and then come back worse, call your doctor.
You're most contagious during the first 3 to 4 days of symptoms, and you can spread the flu from about a day before symptoms start until roughly a week after. A practical rule many doctors use: stay home until you've been fever-free for 24 hours without fever-reducing medication.
Call your doctor for trouble breathing, chest pain, a fever above 103 that won't come down, a fever that breaks and then returns, confusion, signs of dehydration, or symptoms that last past two weeks. Also call early, ideally within the first 48 hours, if you're pregnant, over 65, or managing a chronic condition, because antiviral medication works best when it's started right away.
Rest and fluids do most of the work, and your immune system does the rest. Fever reducers like acetaminophen or ibuprofen, taken as the label directs, make the days more bearable. The real job is drinking enough, sleeping enough, and easing back in after the first good day.
The flu usually arrives suddenly, with fever, chills, and body aches that put you on the couch within hours. A cold tends to creep in over a couple of days and stays mostly in your head: congestion, sneezing, a sore throat, usually without much fever. If you went from fine to flattened in an afternoon, it's more likely the flu.
BodyBuddy texts you every day of your flu. It keeps count of which day you're on, asks how you slept and where the fever is, nudges you on fluids and rest, and compares how you're doing against the normal arc of a flu. If your symptoms fall outside that arc, it says plainly that it's time to call your doctor. When you're better, the check-ins end.
BodyBuddy carries other recovery arcs too, like colonoscopy prep week and post-op recovery.

When I'm sick, the days blur together and I can never tell whether I'm getting better on schedule. I built BodyBuddy so someone keeps count with you and says plainly when a symptom deserves a real doctor.
