Verdict
The clearest difference is monetization model: Tester at free against wrist/off's free with in-app purchases. Tester also leads on update cadence (every 2 days vs every 6 days) and chart position (#150 vs unranked). wrist/off's advantage is review sentiment (100% vs 90%). On price, ads, in-app purchases and device support there is nothing between them.
