# Digidive vs The Sidewinder Checklist

The clearest difference is price: Digidive at Free against The Sidewinder Checklist's $4.99. Digidive also leads on ratings volume (33 vs 1) and update cadence (every 2 weeks vs every 6 weeks). On rating, ads, in-app purchases and device support there is nothing between them.

Digidive is free to download; The Sidewinder Checklist costs $4.99 up front. Digidive sells 2 in-app purchases, starting at $1.99 per month and The Sidewinder Checklist sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Digidive against 5.0 for The Sidewinder Checklist. That said, the two scores are not equally well evidenced: Digidive has 33 ratings behind it against 1, so its average is the more settled of the two.

Digidive ships an update every 2 weeks, The Sidewinder Checklist every 6 weeks. The most recent releases landed on June 26, 2026 and September 9, 2026 respectively.
