Verdict

The call

The clearest difference is in-app purchases: マルチF at none against Time's 6. マルチF also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.6). Time's advantage is update cadence (every 2 months vs every 6 months). On price and device support there is nothing between them.
