Whether you chant Hare Krishna, Om Namah Shivaya, or any mantra of your choice, Sadhana keeps count so you can stay fully present in your practice. Set a daily round goal and watch your progress build day by day. Each tap counts one mantra. Each completed round brings you closer to your goal. Track your streaks, celebrate milestones, and see your practice grow over time. **What you can do with Sadhana:** - Count mantras by tap, swipe, or auto mode -- your choice of input - Set any number of mantras per round, whether that's 108 for a traditional mala or any count that fits your practice - Switch between Mantras and Rounds as your goal type, depending on how you measure your sadhana - Track today's rounds, weekly progress, monthly totals, and yearly counts - View your full session history by date or by mantra - Set your own milestone thresholds for streaks, mantra counts, and rounds - Earn achievements as your practice deepens over time - Personalize your counter with any deity image or personal photo - Choose from multiple color themes to match your energy - Feel every count with haptic vibration and a bell on round completion Your practice is yours. Sadhana gives you the flexibility to track it exactly the way you want, and the consistency to keep showing up every day.

Verdict
The clearest difference is ads: Sadhana at none against Co's shown. Sadhana also leads on iOS requirement (15.1 vs 17.6). Co's advantage is update cadence (every 4 days vs every 11 days). On price, in-app purchases and device support there is nothing between them.
