Unauthorized or Hidden Subscription Charges
Users report being charged without clear consent, often after a free trial that wasn't properly communicated. Charges appear immediately or months later, even after deletion or cancellation.
34
reviews
- “Charged me a subscription without authorisation. Stay away.”
- “Paid for a 60% off trial, then offered a 7 day free trial, and didn’t like it, so deleted- have now been billed automatically for the full price 3 months later.”
- “I purchased a single month of Deepstash, to try it out. I didn't want an ongoing subscription. You've just charged me for a 2nd month.”
Impossible or Broken Subscription Cancellation
Users cannot cancel subscriptions through the app or Apple Account, with links leading nowhere or failing silently. Some report charges despite cancellation attempts.
28
reviews
- “Have tried several times to cancel and it won’t. Wouldn’t risk a trial.”
- “The cancel subscription link doesn’t actually cancel. They’re just helping themselves to my money.”
- “I cancelled via apple and then app charged me shocking 22 pound membership while I didn’t agree or can see on my apple account.”
Poor or Repetitive AI-Generated Content Quality
Reviews criticize the summaries as generic, poorly written, repetitive, and lacking depth—often indistinguishable from ChatGPT output.
21
reviews
- “AI summaries are all the same structure and use the same story format.”
- “Rubbish AI generated content + scammy billing practises — Firstly, if you want to learn the key points of a well regarded book you would be better off just asking Chat GPT...”
- “Terrible — Keeps stopping doesn’t play continuously, robot voice”
Misleading Free Trial Promotions
Users feel misled by free trials that either start charging immediately, lack proper warnings, or hide the final cost until after sign-up.
19
reviews
- “The free trial gives you the illusion they won’t charge you until a week later snd they will tell you when the charge is due, but I got an invoice from apple the same day.”
- “They sneakily do NOT mention that this tier has no trial period, meaning payment was immediate.”
- “No warnings given before they take a extremely high yearly subscription fee.”
Unresponsive or Nonexistent Customer Support
Multiple users report no replies to emails, messages, or support requests—even after weeks. Automated responses are seen as inadequate.
15
reviews
- “It takes them nearly 14 days just to respond to my support request, and when they finally did it was nothing more than an automated message.”
- “I’ve reached out 5 times via messenger and email and have had zero reply.”
- “Customer service won’t respond either”
Lack of Free Access or Transparent Pricing
Users resent having no free option, being forced into a paid trial, or not knowing pricing upfront. The absence of a non-pro tier frustrates many.
14
reviews
- “Whole set up with no free option at the end”
- “Not only that, asks for a 5* review before you’ve even started using the app.”
- “Would be nice to see content even for 5 mins without paying”
App Functionality and UX Issues
Reports of poor navigation, broken UI (text overlapping images), audio glitches, and inability to access content after setup.
12
reviews
- “Text moves over pictures, continue button only half on page, so can’t use.”
- “Hard to navigate app and content — So far I cannot navigate this to access any meaningful content.”
- “Audio mode skips and repeats. Useless. Dont waste your money.”
Gender and Content Diversity Bias
Users highlight a lack of female authors in recommendations, calling the algorithm biased and outdated.
6
reviews
- “Not a single female author in the suggestions. Archaic.”
- “Very little in the way of female authors. Found it very difficult to find anything to read I was interested in.”
- “Enforced paywall during onboarding is awful. The first book I’m recommended is one I’ve swiped ‘no’ on during onboarding.”
