### 1/5 — Stole Money and don’t reply

*2026-02-11*

I downloaded this app and then forgot about it. Next thing you know, they’ve been charging me a monthly fee since June, it’s now the middle of February. When I go into the account, it says I’m on free. So why are they charging me. I’ve sent emails and no one‘s bothered to get back to me. I would be very careful. I am very disappointed and feel super ripped off.

**Developer response:** This has been refunded.

We should have told you that directly instead of leaving your emails unanswered, and that part is on us.

For anyone reading this, here is how the billing works. The plan and the price are shown before you confirm, auto renewal is part of the terms you agree to at that point, and the payment is verified at the time of purchase. Nothing starts quietly in the background, and you can cancel at any time from your account settings.

If a charge of your own does not look right, write to hi[at]glasp.co and we will look into it with you.

### 5/5 — Highlight to learn

*2025-09-30*

Using it to learn the Quran on a deeper level by comparing and contrasting how various translators translate The Words of Allah subhanahu wata'ala.

**Developer response:** Comparing how different translators render the same passage is exactly the kind of reading Glasp is built for, and this is one of the best uses of it we have heard. Thank you for sharing it.

### 2/5 — Dog **** app

*2025-01-30, version 2.8.0*

Doesn’t even grab a transcript from YouTube. There’s plenty of better read later apps out there. I would like to see a way for YouTube videos to be shared to the glass app where the transcript and maybe ai tools like summary or queries are available. Being then able to export with title original link whatever else to a notes app?!??

### 5/5 — Love the app

*2024-11-26*

Amazing! They add more features to the iOS mobile app!

**Developer response:** Thank you, this means a lot to a small team. If there is anything you want Glasp to do that it does not do yet, hi[at]glasp.co reaches us directly.

### 4/5 — Pretty good highlighting app

*2024-10-14, version 2.2.0*

Decent syncing across platforms.

Only problem is that it is sometimes buggy and can’t highlight certain words or combinations of words on iOS and iPadOS

Please look into this, thank you

Great app

### 5/5 — Great innovative app

*2024-09-18*

The app got me through uni. Constantly reading research articles and knowing everything I’ve highlighted can be found in one place and organised. Worked flawlessly on my MacBook. When using it on my iPad unfortunately it’s got a few hiccups. Sometimes it works on safari & often doesn’t work. Sometimes it highlights notes & sometimes just stops working or won’t sign me in. But it works flawlessly on my MacBook. Thank you for creating such a cool app, please keep it going

### 5/5 — Great app!

*2024-09-04*

I'm really enjoying using Glasp :)

### 4/5 — Iphone老机型

*2024-04-26*

我用的是iPhone7的手机，无法升级到IOS16，你们能否提供能支持老机型的APP？

**Developer response:** 感谢您的反馈，也让您久等了。

Glasp iOS 版目前需要 iOS 15.1 或以上。iPhone 7 可以升级到 iOS 15，因此现在应该可以正常使用了。

如果安装或使用时遇到问题，请写信到 hi[at]glasp.co 并告诉我们具体的错误信息，我们会协助您。

## Version history (last 5 releases)

### 3.9.1 — 2026-08-19

Glasp 3.9.1

• Chat about any page you're reading — ask questions, get answers grounded in the page, and pick Fast, Balanced or Deep depending on how much thinking you want. It's the same conversation you'd see on the web or in the browser extension.
• Help & Support now lives in More: a link to the FAQ, and a Contact Us that opens your mail app with your version and device already filled in.
• Tap the timestamp on a YouTube highlight to jump straight to that moment in the video.
• Highlighting works again on public government pages — reports, statistics and legislation. Signed-in portals like tax and immigration stay off, as they should.
• Opening a Glasp link from the web now lands where it should instead of a "not found" screen.
• Summaries and answers render code, quotes, lists and tables properly.

### 3.8.3 — 2026-08-05

Glasp 3.8.3

• Triple-clicking the last paragraph of a ChatGPT answer now creates a highlight instead of doing nothing.

• Bug fixes and stability improvements.

### 3.8.2 — 2026-07-17

Glasp 3.8.2

• Privacy: the Safari extension and the in-app Reader now stay off sensitive sites — banking, sign-in, health, and similar — matching the desktop browser extension.
• These privacy protections can now update automatically, without waiting for an app update.
• Bug fixes and stability improvements.

### 3.8.0 — 2026-07-14

Glasp 3.8.0

• You can now rate Glasp right in the app — a quick, native review prompt may appear after you've saved highlights or finished a summary. Once in a while at most, never in the middle of what you're doing.
• Fixes and polish under the hood.

### 3.7.0 — 2026-07-08

Glasp 3.7.0

• Highlighting now feels alive — a gentle haptic tick as you extend a selection and a satisfying tap when your highlight lands (English and Japanese alike).
• New ink-wash animation — highlights soak softly into the page as they're created, in articles, PDFs, and YouTube transcripts.
• Prefer it quiet? Toggle haptics under More → Haptic Feedback.
• Lock Screen widget — add Glasp Feed to your Lock Screen to see the latest video from channels you follow.
• Glasp now lets you know when a new version is available, so you never miss improvements.
• Fixes and polish.
