Verdict
The clearest difference is rating: Bolt Reader® at 4.7 against Measure Angles's 4.2. Bolt Reader® also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Measure Angles's advantage is ratings volume (2K vs 7) and update cadence (fortnightly vs every 5 weeks). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Measure Angles sells 10 in-app purchases, starting at $2.99 per 7 days and Bolt Reader® sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Bolt Reader® holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Measure Angles has 2K ratings behind it against 7, so its average is the more settled of the two.
