Verdict

The call

The clearest difference is ads: Projekt at none against Deun's shown. Projekt also leads on update cadence (fortnightly vs every 5 months). Deun's advantage is monetization model (ad-supported vs free with in-app purchases) and iOS requirement (15.6 vs 18.6). On price, review sentiment, in-app purchases and device support there is nothing between them.
