# W18 Alarm vs BitVision

The clearest difference is rating: BitVision at 4.6 against W18 Alarm's 1.3. BitVision also leads on ratings volume (1.5K vs 6) and review sentiment (19% vs 11%). W18 Alarm's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

BitVision holds the better App Store score, 4.6 against 1.3. That said, the two scores are not equally well evidenced: BitVision has 1.5K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 11% of W18 Alarm's written reviews are positive against 19% of BitVision's.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on November 2, 2026 and November 13, 2026 respectively.
