# PreparaTest vs OposSCS

The clearest difference is ads: PreparaTest at none against OposSCS's shown. PreparaTest also leads on update cadence (every 5 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. PreparaTest sells 3 one-off in-app purchases and OposSCS sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

PreparaTest ships an update every 5 days, OposSCS fortnightly. The most recent releases landed on September 11, 2026 and September 17, 2026 respectively.
