Verdict
This is a PDF reader with real crash and iCloud sync problems that reviewers keep hitting, alongside a genuinely easy-to-use annotation interface when it isn't misbehaving. It's cheap and functional for basic reading, but the export and cloud issues suggest it hasn't kept pace with how people actually store files now.
Best for
Someone who wants a low-cost PDF markup tool for files already sitting locally on their device, and doesn't rely on iCloud or Google Drive to move documents around.
Dealbreaker
Multiple reviewers report the app crashing specifically during scanning, saving, or exporting documents, and it does not work reliably with iCloud files — a serious problem if you need to get a signed or annotated PDF out to someone else.
The facts.

Where we recommend it
Apps nobody maintains any more ›Paid apps still on sale years after their last update.
Alternatives with the same rule.
Every app here is still for sale, still well reviewed, and has gone at least three years without an update. That is not automatically bad — some software is simply finished — but you should know before you pay. Also with a catch.

Verdict. Reviewers consistently call this a fast, accurate unit converter with no ads, and it's kept a high rating over hundreds of reviews. It hasn't changed in years, so what you see is what you get: a keypad-driven converter and nothing more.
Best for. Someone who wants a no-frills, ad-free unit converter for everyday conversions and is fine paying more upfront to never see a subscription prompt again.
Dealbreaker. It costs noticeably more than typical unit converter apps, and with no updates in years you're trusting that its unit database and iOS compatibility won't need fixing down the line.

Verdict. A one-time-purchase white-noise app that reviewers praise for ease of use and sound variety, with no subscription and no ads. A small but consistent number of reviewers report crashes on launch, which matters more for an app you rely on every night.
Best for. Someone who wants a simple, no-subscription white noise machine for sleep and doesn't need cloud sync or custom sound imports.
Dealbreaker. A handful of reviewers report the app crashing on open, sometimes right after purchase, and it hasn't been updated in years so that's unlikely to get fixed.

Verdict. A simple sound library that does one job: play recorded ambient sounds to help you sleep, without draining your battery. It hasn't changed in years, but reviewers say the core recordings and ease of use still hold up.
Best for. Someone who wants a no-fuss collection of ambient sleep sounds on an iPhone and doesn't need alarm features or new content added over time.
Dealbreaker. Reviewers note you can't use the sounds as morning alarms, and with no updates in years, don't expect that or any other new feature to ever show up.
