Verdict
The clearest difference is in-app purchases: Session at none against Only One Thing's 1. Session also leads on ads (none vs shown) and iOS requirement (13.2 vs 15.1). Only One Thing's advantage is update cadence (every 9 days vs every 4 months). On price and device support there is nothing between them.
