Verdict

The call

The clearest difference is ads: Delta at none against HotS Helper's shown. Delta also leads on rating (4.8 vs 4.3) and monetization model (free vs free with in-app purchases). HotS Helper's advantage is review sentiment (90% vs 81%) and iOS requirement (15.0 vs 17.4). On price, in-app purchases and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Delta sells 4 in-app purchases, starting at $5.00 per month and HotS Helper sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Delta holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Delta has 28K ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 81% of Delta's written reviews are positive against 90% of HotS Helper's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Delta ships an update every 4 weeks, HotS Helper every 4 months. The most recent releases landed on November 13, 2026 and November 2, 2026 respectively.
