# IRS vs Spell Check

The clearest difference is rating: Spell Check at 4.4 against IRS's 3.0. Spell Check also leads on review sentiment (35% vs 0%) and ratings volume (548 vs 6). IRS's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Spell Check sells 3 in-app purchases, starting at $1.99 per 7 days. IRS asks for nothing beyond the download.

Spell Check holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Spell Check has 548 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 0% of IRS's written reviews are positive against 35% of Spell Check's.

IRS ships an update every 3 months, Spell Check every 6 weeks. The most recent releases landed on October 23, 2026 and October 22, 2026 respectively.
