Verdict
The clearest difference is review sentiment: TuDime at 100% against Hi's 57%. TuDime also leads on rating (4.8 vs 3.1). Hi's advantage is in-app purchases (none vs 2) and update cadence (daily vs every 3 weeks). On price, ads, device support and iOS requirement 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. TuDime sells 2 one-off in-app purchases. Hi asks for nothing beyond the download.
TuDime holds the better App Store score, 4.8 against 3.1. That said, the two scores are not equally well evidenced: Hi has 47 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 57% of Hi's written reviews are positive against 100% of TuDime's.
Hi ships an update daily, TuDime every 3 weeks. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
