# WeightSnap vs Vialy

The clearest difference is in-app purchases: Vialy at none against WeightSnap's 3. Vialy also leads on update cadence (every 2 days vs weekly). WeightSnap's advantage is ratings volume (90 vs 2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. WeightSnap sells 3 in-app purchases, starting at $7.99 per month. Vialy asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for WeightSnap against 5.0 for Vialy. That said, the two scores are not equally well evidenced: WeightSnap has 90 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

WeightSnap ships an update weekly, Vialy every 2 days. The most recent releases landed on October 18, 2026 and October 15, 2026 respectively.
