Verdict
The clearest difference is price: Practis at Free against Theory Lessons's $2.99. Practis also leads on update cadence (monthly vs every 4 months). Theory Lessons's advantage is in-app purchases (none vs 1) and chart position (#15 vs unranked). On ads, device support and iOS requirement there is nothing between them.
