Verdict

The call

Imprint and Liminal both sit at 4.8 stars, but that hides the real split: 100% of Liminal's written reviews are positive against 38% of Imprint's. Liminal also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Imprint's advantage is ratings volume (60K vs 5) and update cadence (every 4 days vs every 11 days). On price, rating, in-app purchases and device support there is nothing between them.
