Videos and audio stay on this phone unless you share them yourself, and no account is needed.

Verdict
The clearest difference is in-app purchases: FitUnlock at none against Plank Form Timer's 1. FitUnlock also leads on ads (none vs shown). Plank Form Timer's advantage is update cadence (every 2 weeks vs every 4 months). On price, device support and iOS requirement there is nothing between them.
