# GoTall vs Relentless

The clearest difference is ads: Relentless at none against GoTall's shown. Relentless also leads on review sentiment (33% vs 22%). GoTall's advantage is ratings volume (6.8K vs 23) and iOS requirement (15.4 vs 26.0). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. GoTall sells 15 in-app purchases, starting at $1.99 per 7 days and Relentless sells 2 in-app purchases, starting at $12.99 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 — 4.6 for GoTall against 4.7 for Relentless. That said, the two scores are not equally well evidenced: GoTall has 6.8K ratings behind it against 23, so its average is the more settled of the two. Written reviews are what separate them: 22% of GoTall's written reviews are positive against 33% of Relentless's.

GoTall ships an update every 9 days, Relentless every 2 weeks. The most recent releases landed on October 15, 2026 and September 23, 2026 respectively.
