Tips for choosing a smartphone app to remind you to take your pills:

Check whether it's available for your smartphone's operating system.

Ask your doctor's opinion.

Start with a free or low-cost app. Search your app store for "medication reminder."

Keep it simple. Apps can come with many features. If you only want reminders to take your pills, that's all you need.

For privacy, pick apps with password protection.

If your life is hectic, consider one with a snooze function.
