Verdict

The call

The clearest difference is in-app purchases: コツログ at none against Simple Notes's 3. コツログ also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). Simple Notes's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price there is nothing between them.
