The best mewing apps
Read the first entry before you install anything. It is the one that answers the question.
Tongue posture does not remodel adult facial bone, and no app changes that. The claim originates with orthodontic work on children whose facial growth was still in progress, where jaw development genuinely can be influenced; extending it to a twenty-five-year-old is an extrapolation nobody has demonstrated. What correct tongue posture does support is real but smaller: swallowing pattern, mouth breathing and the tongue position that keeps an airway open, all of which are legitimate clinical concerns and all of which are treated by a myofunctional therapist rather than by an app. So the honest list is short. Reminder apps are good at reminders. Measurement tools give you a gonial angle to check against, which is how you find out that nothing moved. And a therapist addresses the thing that actually has evidence behind it, which is usually not the thing people came for.
Who wrote this
Fazly wrote this page and Fazly is on this list. Everything here about another product is either a fact about what kind of product it is or the same thing our comparison page says — no prices, no feature lists, nothing that goes stale without us noticing. Where the honest answer is not us, the recommendation says so.
The list
- 1
A myofunctional therapist or orthodontist
Best for
The parts of this that have evidence: swallowing pattern, mouth breathing, airway and tongue tie. If any of those apply to you, this is the entry that matters.
What it cannot do
It will not promise you a jawline, because the clinical literature does not support one in an adult.
- 2
Any reminder or habit app you already have
Best for
Tongue posture is a habit, and a habit needs a reminder rather than a dedicated app. A repeating alarm does the entire job for free.
What it cannot do
It measures nothing, so it cannot tell you whether the habit produced anything.
- 3
Fazly
Best for
You want the measurement and the arithmetic behind it, free, without an account, and without the photo leaving your device.
What it cannot do
It measures; it does not judge. Every target it scores against is a stated convention rather than a finding about attractiveness, and Fazly says so on every page — which is honest and is also less satisfying than a verdict.
- 4
Dedicated mewing apps
Best for
You want the posture instructions and a streak in one place, and the structure genuinely helps some people stick to a habit.
What it cannot do
The category is built around a before-and-after that adult bone does not do, and progress photos taken at different angles will show you a change that is not there.
- 5
A camera on a tripod at a fixed distance
Best for
Actually testing the claim on yourself: same distance, same lens, same light, same head position, once a month.
What it cannot do
It requires the discipline the app was supposed to supply, and the honest result after six months is usually no measurable change.
If you only take one thing from this page
A myofunctional therapist, if you have a swallowing, breathing or airway concern — that is the part of this with evidence behind it and it is a real clinical problem worth solving. If you just want to try tongue posture, the reminder you already have on your phone does the job, and measuring your gonial angle monthly is how you find out what happened. Our guide to doing it correctly says the same thing at more length.
How this list was ordered
Ordered by evidence. The first entry treats the thing that has been demonstrated; the last is the only way to check the thing that has not.
Questions
Do mewing apps actually work?
As habit reminders, yes. As a way to change adult facial bone, no — that is not something tongue posture has been shown to do, and an app cannot change the underlying claim.
How long does mewing take to work?
It does not, in the sense the question means. There is no timeline for adult bone remodelling from tongue posture because there is no demonstrated effect to put a timeline on. Swallowing and breathing patterns can improve with therapy in months.
Is mewing safe?
Resting your tongue on the palate is harmless. Forceful jaw clenching, aggressive thrusting or anything that causes jaw pain is not, and jaw pain is a reason to stop and see a dentist rather than to push harder.
