Verdict
The clearest difference is ads: Time Twin at none against Shells's shown. Shells's advantage is ratings volume (22 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.
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. Time Twin sells 1 one-off in-app purchase and Shells sells 4 one-off in-app purchases. 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 Time Twin against 5.0 for Shells. That said, the two scores are not equally well evidenced: Shells has 22 ratings behind it against 1, so its average is the more settled of the two.
