# Tempdrop vs Harmony Within

The clearest difference is review sentiment: Harmony Within at 100% against Tempdrop's 38%. Harmony Within also leads on rating (5.0 vs 4.2) and update cadence (monthly vs every 3 months). Tempdrop's advantage is ads (none vs shown) and ratings volume (710 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Tempdrop sells 6 in-app purchases, starting at $2.99 per month and Harmony Within sells 2 in-app purchases, starting at $10.00 per month. Whichever you choose, the download price is not the number that matters.
