Most people don't need another lecture about flossing. They need a system that makes
ninety seconds a day automatic.
The short answer: there isn't one best flossing app. Pick the one built
around the reason you keep quitting: nobody notices, there's no consequence, or it's one
more thing to remember.

Friends who see your streak and can nudge you

A hard consequence: your apps stay locked until you floss
Four different bets on why people stop: nobody notices, no consequence, the wrong moment, too much friction.
FlossBros Ours
Best for: People who stick with habits when someone else can see them.
One tap a day, streaks and badges, reminders at a time you pick, Floss Academy lessons with sources, and friends who see your streak and can send a nudge or a high-five.

Called FlossGate inside the app. You choose apps to lock with Screen Time, and they stay locked until the front camera sees you floss for about 45 seconds. Detection runs on the device.
Streak badges at 7, 30 and 90 days, and a parent passcode that locks the settings; its website suggests it for families.

Streaks
Best for: One app for flossing and every other daily habit, on Apple devices.
A paid habit tracker that won an Apple Design Award in 2016 and is an App Store Editors’ Choice. Flossing is one habit among up to 24; older versions suggested it out of the box.
You can share any task with other Streaks users, who see your progress, but nothing is flossing-specific: no lessons and no report for your dentist, though you can export your history as a CSV file. CNET’s Gael Cooper wrote about using it to floss for 100 straight days.

A free, open-source habit tracker with no ads and no account. Add “Floss” as a habit, set a reminder, and it tracks your consistency with a habit score that doesn’t drop to zero after one missed day. Last updated in September 2025.

Waterpik Water Flossing app. Still recommended in older articles, but its App Store and Google Play pages return “not found”.
Flossify. A website describes a flossing tracker with a free trial, but we found no app on the App Store or Google Play.
“Flossy”. Named on at least one dental-practice blog. The only project with that exact name we found is an unpublished code project on GitHub (not Flossy42, which is listed above).
How we checked
On 19 September 2026 we read each app's current App Store or Google Play listing, its
privacy label and its developer's own site. We use FlossBros every day. We didn't install
the other apps, so everything we say about them comes from those listings, labels and
sites. For each app we noted:
How you log (one tap, per meal, or on camera)
Reminders: when they come, or whether any are listed
What keeps you going: streaks, friends, rewards or a hard lock
Whether you can show your history to a dentist, and in what form
Price, platforms, whether you need an account, and the privacy label
We don't show star ratings. Several of these apps, ours included, have too few ratings to
mean much, and the numbers change; check each listing. Nobody paid to be here, and there
are no affiliate links.

The short version
If you floss alone and keep quitting, add accountability. That's the gap FlossBros is built
for. If reminders never worked and you need a hard stop, Go Floss Yourself! locks the apps
you choose until you floss. If you
already have a habit system you love, add flossing there and save the download. If
meal-based logging matches how you live, try Flossy42.
The best flossing app is the one you'll open tonight.
FlossBros is a habit tool, not dental advice, and so is every app on this page. If your gums
bleed regularly, see a dentist.
Questions
Flossing apps, answered
What is the best flossing app?
There isn't one best app; it depends on why you keep quitting. If you stick with habits when someone can see them, FlossBros (our app) is built for that. If you need a hard consequence, Go Floss Yourself! locks chosen apps until you floss. If you already use a habit tracker, add flossing to Streaks on iPhone or Loop on Android.
Is there a free app that reminds you to floss?
Yes. FlossBros is free with no ads and reminds you at a time you pick. Flossy42 is free with ads and reminds you after each meal time you set. Loop Habit Tracker, free and open source on Android, can remind you about a “floss” habit you create.
Is there a flossing app I can use with friends?
FlossBros is built around it: friends see each other's streaks and can send a nudge or a high-five, with up to 5 friends free. Streaks, a paid habit app for Apple devices, can share any task with other Streaks users. Flossy42 has an opt-in global leaderboard rather than friends.
Can I show my dentist my flossing history?
Yes, in a few apps, as a self-reported log rather than a clinical record. FlossBros exports a PDF of your log on Premium. Gumline exports a summary for your dentist, or CSV and JSON. Floss: Oral Health Tracker creates progress summaries to share, with detailed reports on Premium.
Is there a flossing app for Android?
Few. In September 2026 we found no dedicated flossing tracker on Google Play with a real track record. FlossBros for Android is in a closed beta you can ask to join. Otherwise, add a “floss” habit to Loop Habit Tracker (free, no account), or use quip, which logs flossing next to brushing.
Which flossing apps don't collect data?
By their App Store privacy labels, Good Job You Flossed!, Go Floss Yourself! and Gumline collect no data, and Loop's Google Play listing says the same. FlossBros lists contact info, identifiers and diagnostics as not linked to you. Flossy42 and quip list usage data used to track you. Developers write these labels themselves.
Do flossing apps actually work?
We don't know of a clinical trial of any consumer flossing-streak app, ours included. What is established: the American Dental Association recommends cleaning between your teeth once a day, and in the best-known habit study a new daily behaviour took a median of 66 days to feel automatic. An app can't floss for you. It can make remembering easier.
What's the difference between FlossBros and a general habit tracker?
A general tracker like Streaks ($5.99 once, Apple devices) or Loop (free, Android) treats flossing as one task among many, and works well if you already live in one. FlossBros is only about flossing: friends and nudges, Floss Academy lessons with sources, and a PDF log for your dentist on Premium.
