Verdict

The call

The clearest difference is ads: Letter Laboratory at none against Last Extract's shown. Letter Laboratory also leads on monetization model (free vs ad-supported). Last Extract's advantage is update cadence (every 5 days vs every 3 weeks) and iOS requirement (15.0 vs 18.2). On price, in-app purchases and device support there is nothing between them.
