Verdict

The call

The clearest difference is review sentiment: MechaOBD at 100% against TotalAV's 24%. MechaOBD also leads on update cadence (every 3 days vs every 6 weeks) and rating (5.0 vs 4.6). TotalAV's advantage is ratings volume (72K vs 2) and chart position (#86 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. TotalAV sells 9 in-app purchases, starting at $4.99 per month and MechaOBD sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
