# HCF vs Focus Bubble

The clearest difference is in-app purchases: Focus Bubble at none against HCF's 2. Focus Bubble also leads on ads (none vs shown) and update cadence (every 3 days vs fortnightly). HCF's advantage is ratings volume (9 vs 1). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. HCF sells 2 in-app purchases, starting at $3.99 per month. Focus Bubble asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for HCF against 5.0 for Focus Bubble. That said, the two scores are not equally well evidenced: HCF has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

HCF ships an update fortnightly, Focus Bubble every 3 days. The most recent releases landed on October 21, 2026 and October 6, 2026 respectively.
