Verdict
The clearest difference is in-app purchases: SH4 DESIGNER at none against Flashly's 2. SH4 DESIGNER also leads on ads (none vs shown) and iOS requirement (11.0 vs 15.0). Flashly's advantage is update cadence (every 3 weeks vs every 7 months). On price and device support there is nothing between them.
