### 1/5 — Does not work.

*2026-08-04*

The developer of this app does not believe Hilo is introduced in the United States.  However Hilo  was introduced to the US market in mid July 2026.   So my review stands.   The app does not seem to work with the US export of Hilo Core data.

**Developer response:** Thank you for your review. It's best to raise a support query in the future for a faster resolution. We have a fix for USA region reports which will be available in 2.0.1

### 1/5 — Terrible app

*2026-08-03*

I have spent several hours and can’t get it to work.

**Developer response:** Thank you for your review, we are sorry you've had a bad experience. The documentation is linked from our app and details how to scan the Hilo reports. If you are in need of assistance then please contact our support team.

### 1/5 — Not working

*2026-07-16*

Only export model is copy to clipboard completely useless

**Developer response:** Thank you for taking the time to review our app. It's difficult to know what fault you find in our app. It successfully copied the datapoints to the clipboard for you. Please take the time to view our help pages to see the many ways you can export your data and all for a small amount of money with no subscription needed.

### 1/5 — Daten werden nicht vollständig gescannt

*2026-07-13*

Die App ist so nicht brauchbar. Von 244 Datensätzen werden nur 161 gescannt. Eine Kontaktaufnahme zur Fehlermeldung über die angegebene Support-Seite ist nicht möglich, da die notwendige Registrierung dort scheitert.

**Developer response:** Vielen Dank, dass Sie sich die Zeit genommen haben, unsere App zu bewerten. Wir sind vor Kurzem zu einem neuen E-Mail-Anbieter gewechselt; die Probleme sollten jedoch behoben sein, sodass Sie nun ein Support-Ticket erstellen können sollten. Mit Version 2.0 führen wir eine wesentliche Verbesserung der App ein, durch die Ihr Problem beim Scannen behoben werden dürfte.

### 4/5 — Needs a ‘reset settings to default’ button…

*2026-06-18*

A good way to work around Hilo deliberately limiting its sync capability to Apple Health.
This app does need a reset setting feature. I’ve messed around with them & I can’t remember what they were to put them back again.

**Developer response:** Thank you for your review, please update to the latest version 2.0 when it becomes available in your region. This will add a reset feature.

**Developer response:** Thank you for the review. We have a new 2.0 being released which should resolve your issue. Please leave feedback on our support link if you still have any issues.

### 4/5 — Worth the money

*2026-02-28*

A good way to work around Hilo deliberately limiting its sync capability to Apple Health.
This app does need a reset setting feature. I’ve messed around with them & I can’t remember what they were to put them back again.

**Developer response:** Thank you for your review, yes we will update to add a reset feature in the next version.

### 1/5 — Empty Screen

*2025-11-18*

No DATA extracted. Does Not Work on iPhone 12 Pro

**Developer response:** With the limited information you've provided it looks like you've not scanned a report. The instructions are on our website which is linked on our App Store page. If you need further assistance then you should raise a ticket here https://4puretech.co.uk/open-ticket/ as a review forum is not the place to diagnose issues.

### 5/5 — Works get

*2025-11-16*

I don’t get the negatives reviews. This app does what it says. I hate Hilo’s app restrictions. The fact that BpExtrat is even necessary tells you a lot about Hilo as a company. Bpextract solves the problem of not having all your BP readings in AppleHealth. I just wish it was possible to have it happen automatically. But at least it’s easy. Thanks for making this.

**Developer response:** Thank you for taking the time to review our app, we are happy to hear that it is useful for you. Thanks for sharing your experience!

### 3/5 — Please review the stuff!

*2025-07-28*

Sometimes diastolic bp will consider as systolic, and hr as diastolic. Currently i don’t know what triggers this datashift. Played with anomaly detection but resulted data loss. Want to help debugging this, because unpredictibility renders this stuff useless.

**Developer response:** Thank you for the review. Please can you update to the latest version, we have fixed an issue with the left hand column scanning which should resolve these issues. Please leave feedback on our support link if you still have any issues.
