You already know the deal you made with spaced repetition. Show up every day, clear what is due, and the cards space themselves out so almost nothing is ever truly hard. Miss a few days and the deal quietly inverts. The cards you would have seen pile onto the cards you have not seen yet, the easy ones come back interleaved with the ones you were dreading, and a queue that was twenty minutes becomes the kind of number you do not want to look at before coffee.
That is the strange thing about Anki that no other study tool does to you. The work is not waiting politely for when you have time. It accrues. The count goes up overnight, on weekends, on the day of the thing you were cramming for, indifferent to whether you opened the app. Most people do not quit Anki because the cards got too hard. They quit because they let one day slide, the backlog spooked them, and the spooked feeling sent them straight back to the feed, which is the one place that never shows you a number you owe.
The skip is never the real cost
Skipping a single day of reviews barely dents your retention. What it dents is your willingness to come back. The reviews you do daily are short and forgettable in the best way. The reviews you do after a four day gap feel like punishment, so you flinch, and flinching is how a daily habit turns into a thing you used to do. The whole engine runs on the queue staying small enough that opening it never feels like a decision. The moment it feels like a decision, you have already lost it.
The cards do not wait for you to be ready. They accrue all the same.
So the question that matters is not whether you want to keep up. You do, or you would not have built the decks. The question is what gets to the front of the line at the exact moments you reach for your phone, because those are the same moments the reviews are sitting there undone. Right now the feed is first in line every time, and the deck is one screen over, losing a race it never gets to run.
Make the count go down before the apps open
Here is the move. Put your reviews in front of the apps you reach for, so the easiest path through your phone goes through the deck first. Not a reminder that pings and gets swiped away. The order of things, arranged so that the thing you keep meaning to do becomes the thing your phone opens for.
That is what Tonic does. You pick the apps that pull you off the deck, say Instagram or Reddit, and you set time spent in Anki as what opens them. From then on the queue comes before the feed, by default, on the days you feel like it and the days you do not.

How the time gets counted, honestly
Tonic measures the time you spend with Anki actually open and in front of you, through Screen Time, the same signal your phone already uses to tell you how long you were in any app. It is time on screen, not anything pulled from your health data. There is one honest thing to know: the time counts only while the deck is the app you are looking at. Leaving Anki open in the background while you do something else does not count, and it should not, because the point is the reps, not a stopwatch you can park and walk away from. You cannot idle your way past the deck, which is exactly why the deck stops getting skipped.
When you have put in the time, the apps you chose open on their own. You do not log the session, and you don't even have to open Tonic to claim it. The timing is handled by iOS, so it usually lifts within a minute or so rather than the very instant you finish. A plain blocker can only ever keep an app shut. This is the part it cannot do: let your real reviews be the thing that opens your phone back up.
For the days the count is brutal
Some seasons the queue is not gentle. The week before Step, the run-up to finals, the first month of a fresh deck when everything is new and nothing is mature yet. Those are the days you most need the deck to come first, and also the days you most fear being boxed in. So you stay in charge of how firm it is. On an ordinary day you might set a soft pause you can move through if you genuinely have to, a small one that grows a little each time you reach, enough to interrupt the reflex and let you choose. On a heads-down exam day you might set it to hold until the reps are in. Your call, and you can change it tonight.
And if you truly need a locked app in the middle of a deadline, you are the one holding the dial. Change the rule, take the day, or turn the whole thing off whenever you decide. Tonic is something you set for yourself, the version of you who knows the count compounds handing instructions to the version who is tired at the end of the day. It is not a lock anyone else holds over you, and it is not a parental control.
A blocker keeps an app shut. This lets the deck be the key.
What keeping up actually feels like
The point was never to turn you into someone who never misses a day. You will still miss the odd one, and one missed day was never the thing that broke the habit anyway. The point is the count that greets you tomorrow morning. When the reviews come before the feed most days, the queue stays in the range where opening it is a non-event, the cards stay spaced the way the algorithm meant them to, and the retention you were paying for with all those reps actually shows up when you need it. The streak takes care of itself, because it stops depending on a burst of resolve at the end of a long day and starts being the plain order of how your phone works. The deck got smaller while you were not watching, and that is the whole game.
