This week's discount feed skips the usual mass-market suspects and turns up a genuinely useful mix: a PDF tool with a wild pricing history, a well-reviewed dungeon-keeper roguelike, a flashcard app for students, and two free apps that are honest about their premium upsells rather than hiding them. Five picks, verified live against the App Store as of September 21, 2026.

## SwiftDocs: PDF Document Maker — was $14.99, now $0.99

SwiftDocs handles PDF creation, editing, merging, and annotation on iPhone — scan-to-PDF, form filling, the usual document-utility feature set, aimed at replacing a desktop PDF tool for people who mostly work from their phone. At 4.6 stars across 48 ratings, it's a solid, if modestly reviewed, entry in a crowded category.

Here's the honest part: this isn't SwiftDocs' first trip to $0.99. AppsHunter's price history shows it's bounced between $0.99 and $14.99 at least eight times since 2025, sometimes just weeks apart. That's not a rare "deal" — it's closer to the app's normal pricing rhythm, alternating between a full-price baseline and a promotional floor. The practical upshot is the same either way: if you want it, $0.99 is the price to buy at, and if you miss this window, another one will likely come within a month or two.

## Legend of Keepers — was $6.99, now $0.99

Legend of Keepers flips the usual dungeon-crawler script: you play the dungeon master, setting traps and positioning monsters to stop a rotating cast of over-confident heroes from reaching your dungeon's boss. It's a roguelike run structure with real strategic depth — enemy composition and room order matter — rather than a reskinned tower-defense game.

[Legend of Keepers](https://appshunter.io/ios/app/legend-of-keepers/id6444660338)

At $0.99, an 86% cut from $6.99, it carries the strongest review record in this batch: 4.8 stars across 436 ratings. That's enough volume to trust the score, and the premise is distinctive enough that it's worth a look even if you don't normally play roguelikes.

## SwiftCard: Flashcard Maker — was $12.99, now $0.99

SwiftCard is a straightforward digital flashcard app — build your own decks, import existing sets, and run spaced-repetition-style study sessions. No frills, which is exactly what a lot of students actually want from a study tool instead of a bloated all-in-one app.

[SwiftCard: Flashcard Maker](https://appshunter.io/ios/app/swiftcard-flashcard-maker/id1194924993)

At $0.99 (down from $12.99), it's a 4.2-star app across 74 ratings — solidly fine rather than exceptional, with the rating spread suggesting it does the core job well without wowing anyone on extras. For the price, that's a reasonable trade if you specifically need flashcards and nothing more.

## Gympok: Gym & Fitness Planner — free (was $14.99)

Gympok builds workout plans and tracks gym sessions, with the app itself free to download after a $14.99 listing. Worth knowing going in: Gympok sells weekly ($1.99), monthly ($4.99), and yearly ($19.99) premium passes that unlock its full category library — the free tier gets you started, but the paid tiers are where the complete feature set lives.

[Gympok: Gym & Fitness Planner](https://appshunter.io/ios/app/gympok-gym-and-fitness-planner/id6756432929)

The review base is thin — 4.9 stars from just 11 ratings — which is too small a sample to lean on heavily in either direction. Fine to try free and decide for yourself whether the premium unlock is worth it; just don't expect the small rating count to tell you much on its own.

## Hue9: Color Sudoku — free (was $9.99)

Hue9 reskins classic Sudoku with a color-matching mechanic instead of numbers, which sounds like a small change but noticeably shifts how the puzzles read at a glance. It's free to download now after listing at $9.99, with a single $9.99 "Hue9 Pro" in-app purchase that unlocks additional content permanently rather than through a subscription.

At 4.6 stars across 28 ratings, the core puzzle experience has held up for the people who've reviewed it. Since the free tier is a real, playable version rather than a stripped-down demo, there's no real downside to trying it before deciding whether the one-time Pro unlock is worth $9.99 to you.

## Deals we skipped this week

Not every discount on AppsHunter's feed made the cut. One utility app showed a "was $99.99, now $2.99" headline discount with only two ratings on record — too little signal to trust the original price was ever real, so we left it off. Another app that briefly appeared discounted had already reverted to full price by the time we re-verified it — a reminder that these feeds move fast and every price here was checked live, not pulled from a snapshot. For the pattern behind why some "deals" are more real than others, see our [App Store pricing report](https://appshunter.io/blog/app-store-discount-pricing-report).

## FAQ

**How long will these prices last?**
App Store discounts are set by individual developers and can change at any time without notice. If a price matters to you, buy now rather than waiting.

**Is SwiftDocs actually a good deal, or does it just cycle prices to create false urgency?**
Both things can be true. The pricing genuinely oscillates rather than being a one-off promo, but $0.99 is still a fair price for what the app does — just don't treat this specific window as rare or unrepeatable.

**Are Gympok and Hue9 worth using without paying for the premium unlock?**
Yes for casual use — both free tiers are functional, not crippled demos. Whether you need the paid unlock depends on how deep you want to go with either app.
