Automatic camera backup • Sync will back up photos and videos as soon as you take them. • You can then delete photos from your phone and save space.

Everything happens on your iPhone: no account, no servers. HOW IT WORKS Tap record and talk. The transcript keeps pace with you, written by Apple's on-device speech engine. When you stop, you get the note and the full transcript. Tap any sentence to hear it. Tap a word to fix it, and Whittle remembers the spelling next time.

Verdict
The clearest difference is in-app purchases: Resilio Sync at none against Whittle's 1. Resilio Sync also leads on iOS requirement (11 vs 26.0). Whittle's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). On price and device support there is nothing between them.
