What reviews complain about
from 90 competitor reviews
- “Downloaded free app and my account was billed for $241+”
- “I canceled 2 days before end of trial but they charged me for the full month anyway”
- “This auto renewed after 2 weeks at $21.60 ($9.99 per week). I had used it once.”
- “Beware this app cost you weekly! Does not say anything about subscription when you first click on it.”
A scanner that is actually free or a one-time purchase, with the price shown up front and no trial that auto-converts. The trust gap is the wedge.
- “Junk in the middle of viewing it disappears and you have to go rescan again”
- “I have not been able to get a QR code without it either freezing or crashing”
- “Does not work black screen”
- “Doesn't recognize anything I scan. I have a better job typing in barcode numbers manually into Bing.”
Fast, dependable scanning built on the native VisionKit data scanner. Reliability alone clears most of this field.
- “If you scan a QR code, the website will take you to a site that asks for credit card information.”
- “I do not want to watch porno when I'm trying to get a game on tv”
- “Adware of the nasty kind.”
- “Free QR code scanner? Not hardly! Kept bringing me back to a scanner app I deleted.”
Show the decoded link and warn the user before opening anything, with no third-party ad SDKs. Safety becomes the brand.
- “Too hard to use and counter intuitive”
- “This thing had a QR code that didn't seem to work on where everything goes.”
- “It doesn't show you anything”
One screen, point and scan, result and next action shown instantly. No setup step at all.
Can a solo dev build it
difficulty and risk, broken down
The app is a weekend build since scanning and QR generation are native frameworks with no server. That is also why it is commoditized. The hard part is not the code, it is winning trust and finding a way to earn money without becoming the thing users hate.
If you build it
a one-page brief (a starting point, not the answer)
A fast, honestly free QR and barcode scanner that shows you the link before it opens it.
Everyday iPhone users who got burned by scam scanner apps and want one that just works with no subscription.
Top scanner apps bury weekly charges, fail to scan, or push people to shady sites. People want a plain scanner they can trust.
- ·One-tap scan with the native VisionKit scanner and no setup screen
- ·Show the decoded link or text and warn before opening any URL
- ·On-device history of past scans
- ✕No free trial that flips to a weekly subscription
- ✕No third-party ad networks or link redirects
- ✕No price comparison or product database at launch, since those need a backend and licensing
Open the app, point at a code, see the result, copy it or open it after a safety prompt. Nothing else.
Keep core scanning free with no ads. Charge a one-time price or a small fee for extras like bulk export. Honest, upfront pricing is the whole pitch, so never gate basic scanning behind a trial.
Honest warning
the biggest trap of this opportunity
The real trap is money: iOS already scans QR codes free in the Camera, and the only proven way incumbents earn here is the exact subscription bait users are revolting against.
