Verdict
The clearest difference is ads: VariantDoku at none against KAMI 2's shown. VariantDoku also leads on update cadence (weekly vs every 2 months). KAMI 2's advantage is ratings volume (15K vs 7) and review sentiment (84% vs 75%). On price, rating, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. KAMI 2 sells 7 one-off in-app purchases and VariantDoku sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for KAMI 2 against 4.9 for VariantDoku. That said, the two scores are not equally well evidenced: KAMI 2 has 15K ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 84% of KAMI 2's written reviews are positive against 75% of VariantDoku's.
KAMI 2 ships an update every 2 months, VariantDoku weekly. The most recent releases landed on November 8, 2026 and November 5, 2026 respectively.
