Verdict
The clearest difference is in-app purchases: BUNNlink Mobile at none against Ohms Law Calc.'s 1. BUNNlink Mobile also leads on ads (none vs shown) and rating (5.0 vs 4.7). Ohms Law Calc.'s advantage is ratings volume (1.3K vs 2) and update cadence (every 2 months vs every 7 months). On price and device support 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. Ohms Law Calc. sells 1 one-off in-app purchase. BUNNlink Mobile asks for nothing beyond the download.
BUNNlink Mobile holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Ohms Law Calc. has 1.3K ratings behind it against 2, so its average is the more settled of the two.
Ohms Law Calc. ships an update every 2 months, BUNNlink Mobile every 7 months. The most recent releases landed on October 29, 2026 and October 10, 2026 respectively.
