# Liminal Flow vs ALTERD

The clearest difference is ratings volume: ALTERD at 722 against Liminal Flow's 4. ALTERD also leads on update cadence (fortnightly vs every 2 months). Liminal Flow's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Liminal Flow sells 4 in-app purchases, starting at $4.99 per month and ALTERD sells 19 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
