# Serenis vs Twidddle

The clearest difference is review sentiment: Twidddle at 100% against Serenis's 42%. Twidddle also leads on update cadence (every 3 months vs every 59 months) and rating (5.0 vs 4.6). Serenis's advantage is ratings volume (154 vs 6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Serenis sells 12 one-off in-app purchases and Twidddle sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
