How can I tweak the spacing algorithm in my spaced repetition app?

[DennisLT]

I’ve been trying to use spaced repetition for my studies, but I’m finding the intervals my app sets feel off. Sometimes it shows me a card I clearly know right before a big review, and other times I feel like I’ve almost forgotten something before it asks again. I’m curious if anyone else has tweaked the default spacing algorithm based on their own sense of memory decay.

I’ve tinkered a bit. I marked a handful as hard and let those reset to shorter gaps, but the next review still showed up oddly close to a big deadline. It feels like the memory curve isn’t matching my week when there’s busier days.

I kept a tiny log for a week—card, how well I recalled, how long until the next review. That helped me see some days I was fine and others I was bluffing, which makes me doubt the fixed intervals.

Honestly I’m not sure what’s the real problem—the decay rate, how I encode the material, or just life getting in the way. I tried making some cards a touch harder and a touch longer between reps, and it helped a bit, but it felt messy and inconsistent.

One off topic thought: I wonder if the app’s calendar view is throwing me off. I’ll glance at the day and see three reviews in a row and panic, then later nothing. Then the next day it’s quiet again.
