“We believe that mindfulness is more than a form of stress relief — it can be a tool for personal growth, deeper understanding, vibrancy. More than a way to disconnect — it can be a way to feel a part of something bigger. More than simply silence — it can be immersive, beautiful, moving.”
–Raed Khawaja, Open Co-founder & CEO

The evidence, sources, measurements and versions behind every label above.
Findings that met the published evidence standard.
Surprise charges: raised by 39 distinct reviewers (about 1 in 13 reviews we read)
A large number of reviewers report being charged when they did not expect it — including being charged after cancelling during a free trial, or when a trial turned into a paid plan without warning. We cannot see anyone's billing, so this is published as an attributed user report: what reviewers say, and how many of them said it.
Open observations that have not cleared the evidence bar.
Hard to cancel: raised by 11 distinct reviewers (about 1 in 45 reviews we read)
This observation has not cleared the required evidence standard.
Cancelling the subscription is blocked, hidden, multi-step, or simply does not take effect.
Trial converts to a charge: raised by 16 distinct reviewers (about 1 in 31 reviews we read)
This observation has not cleared the required evidence standard.
The free trial demands a payment method up front and/or rolls into a paid subscription with no usable warning.
500 reviews read for this analysis. Each observation keeps the sample and store it was based on.
Raised by 39 distinct reviewers — about 1 in 13 reviews we read on this store leg (App Store).
Took my money — I signed up for the trial and canceled it, however I’m still charged the $20 for the month. But this purchase doesn’t even show I had a subscription or purchase within my apple account. I would like a refund
Unauthorized Charges — I only signed up for the trial of this app, and cancelled it after a few days. At the end of the period however, they still tried to charge my card $150. Beware of their free trial - it’s a shady practice.
They will charge you even if you cancel the trial — I did the free trial and canceled it before the trial ended. Once I did, the app showed as inactive, but even though I will still charge on a monthly basis twice. When I first reached…
Scam — Worthless. Then cancelling is a nightmare.
Use calm — Charged me and was no way to cancel in my subscriptions. Have had trouble canceling and will not refund. Don’t recommend. Especially for $20 a month.
Hidden billing outside of apple subscriptions — Extremely disappointed in the lack of transparency. This app bypasses Apple’s standard subscription management, making it impossible to cancel through your iPhone settings. I tried to cancel…
Don’t sign up for the free trial — If you forget to cancel the free trial it will charge you $150 which is absurd for an app like this
fair warning — my friend sent me a link to a free trail - i never even used the account but realized i was being charged for 2 months (no warning emails or notifications that the free trial period was over). i cancelled as soon as i…
Scammers — Be MINDFUL when you signup for the free trial - they will charge you after (of course) for an entire YEAR’S subscription.
A sampled review illustrates one person’s experience. It does not establish a finding on its own.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured

openAssessed 2026-10-27 from 500 user reviews, the store listing and its privacy label. We have not scanned the app's package, so nothing on this page was read from inside the app itself.
What the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
This assessment is produced automatically. Three independent signals are read — user reviews, the store listing and the store privacy disclosure — and each candidate finding is filed under the sources that support it.
No charge stands on one kind of evidence — with one published exception. A finding is either a measured fact that anyone can reproduce (an ad SDK is in the package; every subscription bills weekly; the privacy label omits a tracker we can see), or it is an interpretation — and an interpretation needs independent sources to agree before it reaches the catch list. The exception is a harm only users can see: a charge may publish from reviews alone, as “Reported by N users”, once enough reviewers raise it to clear that charge’s own published bar. That agreement rule is what replaced the human reviewer, not a model’s confidence.
There is no overall score, on purpose. A 0–99 number was published here until 2026-09-15. It was withdrawn because it discriminated too weakly to be the instrument — 44.7% of every pair of apps tied — and because a single number is a verdict where a count is an observation. What publishes instead is a row of measurements, each of which says what was counted and, where we could not look, says that instead.
Findings under One source only are real reports we do not stand behind as findings. They are shown because withholding them entirely would hide a genuine complaint, and labelled because publishing them as charges would be an accusation off a single source.
