# Sidekick vs QuantFit

The clearest difference is rating: Sidekick at 4.5 against QuantFit's 3.0. Sidekick also leads on update cadence (every 11 days vs every 2 months) and ratings volume (8 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sidekick sells 6 in-app purchases, starting at $3.99 per 7 days and QuantFit sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Sidekick holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Sidekick has 8 ratings behind it against 1, so its average is the more settled of the two.

Sidekick ships an update every 11 days, QuantFit every 2 months. The most recent releases landed on October 14, 2026 and October 11, 2026 respectively.
