# Smartoo vs TACHS Prep

Smartoo and TACHS Prep are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Smartoo sells 5 in-app purchases, starting at $5.99 per month and TACHS Prep sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on October 30, 2026 and November 10, 2026 respectively.
