FIVIT's open-arc dial
72% Recovery

Last night's heart-rate variability and resting heart rate, set against your own 30-day normal, plus how much of your sleep you got.

Four tabs, all of it yours

Worked out on your phone, from your own data, against your own normal.

The Today tab: a 70% recovery dial with strain and sleep dials below and a morning briefing.

Today

Recovery, strain and sleep at a glance, and a short note on what to do with them.

The Trends tab: breathing rate, resting heart rate, HRV and a seven-day recovery chart.

Trends

Your vitals over 7 and 30 days, so a bad night reads as one night and a slide reads as a slide.

The Nutrition tab: calories left, protein, carbs and fat dials, and ways to log food.

Nutrition

Scan a barcode, search Dutch and German supermarket food, or save your own recipes.

The Train tab: a suggested full-body session with sets, reps and effort.

Train

Log sets as you lift, record runs with a map, or add a session your watch missed.

Screens from an earlier build. Yours will look a little newer.

Getting it on your phone

fivit.apk
This type of file can harm your device.
CancelDownload anyway

First, download it on your phone.

Open this page on the Android phone itself and tap Download. Chrome warns about every app that doesn't come from the Play Store. Tap Download anyway.

Unsafe app blocked
This app was built for an older version of Android, or its developer is unknown to Play Protect.
OKInstall anyway

Then let Android install it.

Open the file. Allow installs from Chrome when asked, once. If Play Protect calls the developer unknown, tap More details, then Install anyway. It says that because FIVIT isn't on the Play Store yet.

Steps

Last, give it your health data.

Turn on every Health Connect permission it asks for. Then go to Settings, Apps, FIVIT, Battery and choose Unrestricted, or the morning briefing can't arrive while the app is closed.

What to know

Why does it say "Calibrating baseline"?

Recovery compares last night with your own normal, and it needs seven nights to learn what normal is. Until then it leans on population averages and says so. Wear your watch to bed every night of the first week.

Which watches work?

Anything that writes heart rate and sleep to Health Connect, such as Fitbit and Pixel Watch, or a Galaxy Watch through Samsung Health. Health Connect is built into Android 14 and newer, and is a free app from the Play Store on Android 9 to 13.

Some watches don't share heart-rate variability. Recovery then leans on your resting heart rate, which works, but is less sharp.

Do I have to use the AI coach?

No. You choose when you sign up and can change it in Profile. Your scores never come from AI either way: recovery, strain and calories are plain arithmetic on your phone.

With AI on, your scores, sleep, training and food details are sent to Google Gemini to write the briefing and read meal photos. With it off, nothing about you goes to an AI provider. The AI coach is for people 18 and over.

Where does my data go?

Raw heart-rate samples stay on your phone. Daily summaries, workouts, meals and your profile are stored in a private database so they survive a new phone. Only your account can read them; Ateeksh, as the person running it, technically can. The privacy note has the details.

How do updates work?

Most arrive by themselves: close FIVIT and open it twice, and you have the new version. Bigger ones need a new download; the app tells you, and installing over the top keeps all your data.

Forgot your password?

Tap "Forgot password" on the sign-in screen. The email links to a reset page on this site, where you choose a new one. It works on a laptop too.

Is this medical advice?

No. FIVIT is a training and lifestyle tool. If something it shows worries you, or you feel unwell, talk to a doctor.

How do I leave?

Profile, then Delete account. It removes everything stored about you on the server, at once. Then uninstall the app.

Something off? Tell me

A bug, a number that looks wrong, an idea, or a friend who wants in. It goes straight to Ateeksh.

Opens your email app with this filled in.

Mention your phone model and the app version in Profile.
