TendMark: To Do List & Planner
Reminders, Routines & Events
Only for iPhone
Free · In-App Purchases
iPhone
A birthday to organise. A tablet to remember. A dog waiting for a walk. Give the things on your mind a place to live.
TendMark brings routines, appointments and event checklists together on your iPhone. See what needs attention, tick things off when they are done and look back at what you recorded.
PLAN THE OCCASION, KEEP THE LIST TOGETHER
The card, the cake, the present. The tickets, the packing, the neighbour feeding the cat. Add an event for a birthday, holiday, wedding or another occasion and keep its tasks in one checklist.
• Choose a single date or a date range
• Add notes and up to three optional event reminders
• Tick off items as you go, without creating a separate routine for each one
• Repeat birthdays and anniversaries yearly with a fresh checklist
• Complete the event to save its checklist in History, including anything left unfinished
• Reopen a saved event when you need to make changes, within your plan limits
One-off events leave your active plan when completed or cancelled. Yearly events keep a separate checklist for each occurrence, so next year’s plans do not overwrite this year’s record.
MAKE EVERYDAY ROUTINES EASIER
Create profiles for yourself, people you support, pets, plants, homes, vehicles, equipment and more. Keep the right routines, appointments and events with each profile.
Choose one-off, daily, weekly, monthly, yearly or every-few-days routines. Daily, weekly, monthly and every-few-days routines support up to eight exact times per scheduled day. One-off and yearly routines use one exact time, with advance reminder choices.
Use Done, Taken, Given, Fed, Walked, Watered or your own completion word. Record completed, completed late, skipped or not needed. Pause or archive a routine while keeping its history.
SEE THE DAY AND WHAT COMES NEXT
Today shows what needs attention. Care keeps upcoming routines, appointments and events in date order. History holds your saved outcomes.
Appointments have up to three reminders and their own attended, cancelled or missed outcome. You can also choose to save a separate copy through Apple Calendar’s event editor.
Reminders scheduled for the same minute are combined into one notification. You still review and record each item separately.
A RECORD YOU CAN CHECK
Undo an accidental routine confirmation straight away, or correct a saved routine or appointment outcome with a reason. An unanswered reminder is never treated as proof that something was done or missed.
PRIVATE, WITH NO ACCOUNT TO CREATE
Your profiles, routines, appointments, events, checklists, notes, photos and history stay on your iPhone. No TendMark account, adverts, tracking or analytics SDK. TendMark does not upload your care information to the developer.
Core features work offline. Purchases, restoring purchases and online links use Apple or internet services.

New: Events
Keep the tasks for a birthday, holiday, wedding or another occasion together in one checklist. Add notes and up to three optional reminders, tick off items as you go, then complete the event to save it in History. Yearly events get a fresh checklist, with earlier records kept separately.
Free includes 1 active event with up to 5 items. Premium includes unlimited events with up to 50 items each.
Reminder fix: items scheduled for the same minute now share one notification. Each item keeps its own outcome. Tapping a reminder takes you to Today, or to Care for upcoming items that are not yet in Today. Opening reminders after the app has been closed has also been improved.
New Premium purchases now use the yearly plan. Existing purchases remain recognised.
