The editor actually works.

Spent six hours on a six-minute video in BIGVU, never finished. SmartCaps did it in twenty minutes. Autosave actually saves.

Finally gets Spanglish.

I shoot in mixed English and Spanish and every other app butchered the switch. SmartCaps catches it 99% of the time.

First video was free, watermark-free.

By the time it exported I'd already opened the App Store to upgrade. Best fourteen euros I spend each month.

One price, you can use it.

VEED started adding 'credits' and I gave up. Email from Daniel within three hours on a Catalan question. Renewed yearly on day five.

Cancellation is actually in Settings.

Renewed my year on day five. Cancel is right there in iOS Settings, which is the real difference. Everything else is window dressing.

Caught my mum's Indian English perfectly.

Tried four apps before this. SmartCaps was the first that didn't make her sound like a robot. Switched the whole family.
