# SIide Up vs Stealth Master

The clearest difference is review sentiment: SIide Up at 100% against Stealth Master's 46%. SIide Up also leads on ads (none vs shown) and update cadence (every 4 days vs monthly). Stealth Master's advantage is ratings volume (409K vs 1) and chart position (#80 vs unranked). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. SIide Up sells 1 one-off in-app purchase and Stealth Master sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

SIide Up holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Stealth Master has 409K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of SIide Up's written reviews are positive against 46% of Stealth Master's.

SIide Up ships an update every 4 days, Stealth Master monthly. The most recent releases landed on October 24, 2026 and November 1, 2026 respectively.
