Verdict

The call

The clearest difference is monetization model: Nanotech at free against Length Converter's paid. Nanotech also leads on update cadence (every 2 months vs every 72 months). Length Converter's advantage is ratings volume (12 vs 1). On price, rating, ads and in-app purchases there is nothing between them.
