Verdict

The call

The clearest difference is review sentiment: Calcium at 100% against Bonely's 50%. Calcium also leads on in-app purchases (none vs 3) and iOS requirement (13.0 vs 17.6). Bonely's advantage is rating (4.3 vs 3.7) and update cadence (every 5 days vs every 3 months). On price, ads and device support there is nothing between them.

Both are free to download. Bonely sells 3 in-app purchases, starting at $2.99 per month. Calcium asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Bonely holds the better App Store score, 4.3 against 3.7. Both are backed by a comparable volume of ratings — 3 and 11 respectively. Written reviews complicate that: 100% of Calcium's written reviews are positive against 50% of Bonely's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Calcium ships an update every 3 months, Bonely every 5 days. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
