The clearest difference is rating: Fastra at 5.0 against Fastly's 4.8. Fastly's advantage is ratings volume (96 vs 9). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Fastra sells 6 in-app purchases, starting at $3.99 per month and Fastly sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Fastra holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Fastly has 96 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 100% of Fastra's written reviews are positive against 94% of Fastly's.
Fastra ships an update every 6 days, Fastly every 10 days. The most recent releases landed on October 11, 2026 and October 25, 2026 respectively.
