Verdict
The clearest difference is review sentiment: Programmer Calculator Pro at 100% against Breadpad's 33%. Programmer Calculator Pro also leads on rating (5.0 vs 3.9) and in-app purchases (none vs 3). Breadpad's advantage is price (Free vs $3.99) and update cadence (fortnightly vs every 44 months). On ads and device support there is nothing between them.
