You already trade chores for iPad time
Most parents I know have a rule that goes something like this: "TV doesn't get turned on until ALL chores are done." One mom on r/Parenting said exactly that and added, "Works like a charm." (source)
Another, with kids 6, 8 and 11: "The chores are not mandatory but it's the only way they can earn screen time. If you don't do any chores, you don't get any screen time." (source)

That is a trade. Chores in, minutes out. We do it every day. We just do not write it down.
Why people flinch at the word "reward"
Say "screen time as a reward" out loud and someone will push back. Fairly.
"I am generally against using screen time as a reward because I don't want it to have more value." (source)
"Electronics as a reward is a slippery slope." (source)
And the bluntest, from the top comment on a mom losing the Minecraft war: "Just take it away. I promise they will be okay." (source)
I do not think any of them are wrong. Tweens aged 8 to 12 already average 5 hours and 33 minutes a day of screen media, not counting school, according to Common Sense Media's 2021 census of 1,306 kids. (source) And 71% of parents of kids under 12 told Pew they worry their child spends too much time on screens. (source) Nobody wants to make the iPad shinier.
But "just take it away" does not describe most houses. Most houses have a limit, and inside the limit there is a deal. The question is not whether to trade. It is whether the trade is fair and clear.
Three ways the trade goes wrong
1. The parent is the timer. "When we give her iPad and ask her to shut it down in 1 hour she keeps pushing it off till we argue or shout at her." (source) If you are the clock, every minute is a negotiation.
2. Nobody can remember what was earned. One family tried chores-for-minutes and quit: "The remembering times and what's been earned was overwhelming for us all." (source) Another mom, before starting: "Will this be too much work for me?" (source) Yes, if it lives in your head.
3. The chore is "done" but it is not. "She says she did it, I have to go check, it's half-done, we argue, I give in." (source) The trade collapses at the check.
What a fair trade looks like
Here is what I pulled from the families who said their version works.
Keep the limit and the trade separate. The limit is the limit: one hour a day, none before school, none after 7. That is not for sale. The trade lives inside it. "1hr limit per kid, their rooms must be picked up prior to switch time, no switch before school, no switch or TV after 7pm, they can earn 5-10 min of screen time by helping mom with chores." (source) Chores unlock the hour. They do not stretch it.
Price it in points, not minutes. "X points for 30 minutes video game time, treat at store, pick out cereal of choice." (source) When screen time is one item on a menu next to "pick dinner" and "stay up late," it stops being the only prize. Some kids will pick the late bedtime.
Basics unlock. Extras earn. "They have to do all their basic chores in order to get any screen time. Extra chores earn them points that they can trade in for extra screen time or money." (source) Two lists. The same two lists as every allowance thread.
See the work. A photo of the clean floor ends the "I did it" argument faster than a walk upstairs.
Do not make the app the parent. When a dad on r/daddit proposed a tool that locks the iPad until chores are checked off, the top reply was "Why do you need an app to simply...take away the iPad?" and another asked, "isn't an app like this just training them to follow the app instead of you, the parent?" (source) They have a point. Whatever keeps score should not be the thing that says no. You say no. The list just shows where everyone stands.
What I do
The limit never moves. Inside it, the Switch costs gold. A store can look like this: 30 minutes of game time for 300 gold, stay up 30 minutes late for 150, an ice cream trip for 250, skip one chore for 400. A dishwasher unload might pay 50. When "choose dinner" and "stay up late" sit next to the Switch, the Switch is not the only thing worth earning.
I built the app that holds the store, because I am bad at remembering who earned what. It is called Daily Quest. It does not lock the iPad, on purpose. I still hand it over. The app just records the deal and shows the photo. Ten families are testing it now, and one of the questions I ask each of them is whether the screen-time trade caused a fight. I will publish what they say.
If you do not want an app, a jar of poker chips and a price list on the fridge does the same job. The point is the same either way. You already make this trade. Write it down, price it, and let the kid read the list.
One last thing. A meta-analysis of 128 studies found that expected rewards can lower a person's own interest in an activity. (source) So keep the basics off the price list. Pay for the extras. And keep the limit where it is.
