SmsPlanner is dedicated to professionals who work with customers by appointment. Are you a doctor, lawyer, or do you offer services of various kinds? Do you want to remember appointments or the various deadlines to your customers? SmsPlanner is for you !!! With SmsPlanner you can schedule appointments and deadlines of your customers and then send your personalized SMS, email, WhatsApp, and Telegram to remind individual appointments. To work properly WhatsApp, you must enter the international prefix of cellular numbers in your contacts (eg "+44" for United Kingdom numbers). You can send a SINGLE message for appointment, or a single message with the SUMMARY of the appointments of a given period. It is also possible to send SPECIAL messages (greetings, announcements, communications, etc ...). SmsPlanner can send the appointments to calendars on your iPhone and can synchronize with calendars configured on your Google account. Those who use Google calendars must first add them on the iPhone, and then select them within SmsPlanner by choosing them from the list of iOS calendars. SmsPlanner allows you to specify days and hours for each appointment, but if you get your customers in multiple locations, you can also specify the single address (street and city). In addition, you can print the weekly calendar of appointments. This new version replaces and unifies the previous Free and Paid APP, including all features with no limits and no advertising. There is a free 60-day user license, after which it is possible to purchase further extensions of 1 month, 6 months, or 1 year. If you need to SHARE and SYNCHRONIZE your appointments with all your devices, you can download the dedicated version SmsPlanner-E. This also allows you to PAIR your devices to those of OTHER PEOPLE (colleagues, friends, etc.) via QR code. For suggestions, requests and comments, please write to: info@smsplanner.it NOTE: sending of SMS is done from your iPhone, then the cost of the messages will be charged according to the tariff plan subscribed by your telephone company.

Verdict
The clearest difference is ads: Sms Planner at none against Reminderbase's shown. Sms Planner also leads on rating (5.0 vs 4.5). Reminderbase's advantage is ratings volume (448 vs 1) and iOS requirement (13.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Reminderbase sells 14 in-app purchases, starting at $2.99 per month and Sms Planner sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Sms Planner holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Reminderbase has 448 ratings behind it against 1, so its average is the more settled of the two.
Reminderbase ships an update every 2 weeks, Sms Planner every 3 weeks. The most recent releases landed on October 22, 2026 and October 23, 2026 respectively.
