Verdict

The call

The clearest difference is monetization model: WeightRecord at free with in-app purchases against Fastin's subscription. WeightRecord also leads on review sentiment (50% vs 33%). Fastin's advantage is ads (none vs shown) and ratings volume (10K vs 4). On price, rating, update cadence and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Fastin sells 8 in-app purchases, starting at $6.99 per 7 days and WeightRecord sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

WeightRecord holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Fastin has 10K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 33% of Fastin's written reviews are positive against 50% of WeightRecord's.

UpkeepUpdate frequency

Fastin ships an update every 3 weeks, WeightRecord fortnightly. The most recent releases landed on November 3, 2026 and October 7, 2026 respectively.
