Verdict

The call

The clearest difference is price: Tempo at Free against Jublag's $3.99. Tempo also leads on update cadence (every 5 days vs every 20 months) and iOS requirement (15.1 vs 18.0). Jublag's advantage is in-app purchases (none vs 1). On ads and device support there is nothing between them.
