# invsi vs PK10000

The clearest difference is review sentiment: invsi at 100% against PK10000's 55%. PK10000's advantage is rating (4.3 vs 4.1) and iOS requirement (15.2 vs 17.0). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. invsi sells 4 in-app purchases, starting at $0.99 per month and PK10000 sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

PK10000 holds the better App Store score, 4.3 against 4.1. Both are backed by a comparable volume of ratings — 8 and 6 respectively. Written reviews complicate that: 100% of invsi's written reviews are positive against 55% of PK10000's, so the app with the better star average is not the one people write more warmly about.

invsi ships an update fortnightly, PK10000 every 3 weeks. The most recent releases landed on September 26, 2026 and August 18, 2026 respectively.
