Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. CozySynth sells 1 one-off in-app purchase and VU44 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for CozySynth against 4.9 for VU44. That said, the two scores are not equally well evidenced: VU44 has 14 ratings behind it against 2, so its average is the more settled of the two.
