# Respi vs ZapLock

The clearest difference is monetization model: Respi at free with in-app purchases against ZapLock's subscription. Respi also leads on ratings volume (118 vs 1). ZapLock's advantage is rating (5.0 vs 4.7) and update cadence (every 3 days vs every 8 days). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Respi sells 3 one-off in-app purchases and ZapLock sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ZapLock holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Respi has 118 ratings behind it against 1, so its average is the more settled of the two.

Respi ships an update every 8 days, ZapLock every 3 days. The most recent releases landed on November 11, 2026 and November 13, 2026 respectively.
