Verdict

The call

The clearest difference is review sentiment: Resistor at 50% against Solar APP's 0%. Resistor also leads on in-app purchases (none vs 2) and iOS requirement (13.0 vs 16.0). Solar APP's advantage is rating (4.5 vs 3.0) and update cadence (every 4 months vs every 16 months). On price, ads and device support there is nothing between them.

Both are free to download. Solar APP sells 2 in-app purchases, starting at $9.99 per month. Resistor asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Solar APP holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Solar APP has 46 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 0% of Solar APP's written reviews are positive against 50% of Resistor's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Solar APP ships an update every 4 months, Resistor every 16 months. The most recent releases landed on November 3, 2026 and November 6, 2026 respectively.
