Update 6 - Accuracy Improvements
6.5.2 - 3DS Form Factor Weight
Compare Devices now gives real weight to clamshell and dual screen form factor when DS or 3DS is part of your selected library.
The Form Factor row can now pick a winner when your selected systems actually depend on that shape, instead of always forcing a tie.
6.5.1 - Thor Max 512GB Variant
Added the live Thor Max 512GB listing beside the Thor Max 1TB listing, using the current public Batch 6 store data.
The Thor Max 1TB entry is now labeled more clearly, and both Max variants keep the same Thor hardware sheet with their correct storage and price split.
6.5 - Handheld PC Compare Catalog
Added Steam Deck LCD and OLED models, ASUS ROG Ally models, and MSI Claw models to Compare Devices so more handheld PC hardware can be matched head to head.
These compare entries now carry stored public screen, battery, control, cooling, OS, and chipset data where current official pages expose it.
Battery labels now support public Wh specs, which keeps bigger handheld PC entries more accurate without forcing made up mAh values.
6.4 - Public Hardware Sheet Pass
Filled the remaining live device gaps with public screen, battery, weight, cooling, control, and software fields from current product pages where that data is available.
ANBERNIC, AYANEO, Powkiddy, and Miyoo live entries now lean on stored hardware sheets instead of broad fallback profiles in more of the recommendation and compare flow.
No live device is still sitting at zero hardware coverage after this pass, so confidence and experience scoring have a better base to work from.
6.3 - System Compatibility Pass
Recommendation scoring now checks per system screen fit, controls, touch needs, portability, and software overhead instead of treating raw tier as the whole story.
Compare Devices now adds a Selected Library row when systems are picked, so the compare can reflect your actual library instead of only paper specs.
Why This Fits and confidence notes now call out when certain systems line up especially well or less cleanly on the recommended handheld.
6.2 - Hardware Data Pass
Screen, controls, portability, battery, and software fit now read from stored hardware fields first instead of leaning mostly on profile guesses.
Current handheld entries now show more exact screen and software labels like aspect ratio, panel type, Android version, and OTA support when that data exists.
Confidence scoring now gives more weight to refreshed official hardware data and pulls back when a device still has thin detail.
6.1 - Collected Device Catalog
Added the full collected device catalog and moved every collected device into the live pool for compare and ownership checks.
Current official prices and feature notes were refreshed for active AYANEO, Powkiddy, Logitech G, and Retroid listings where live store data still exists.
Trait mapping now lands more honestly across Windows, Linux retro, cloud streaming, vertical, clamshell, and square handheld shapes.
6.0 - Accuracy Improvements
Added new accuracy inputs for session style, portability, screen priority, controls, software preference, and touchscreen preference.
Recommendation scoring now checks screen fit, control fit, portability, long session comfort, software maturity, and confidence instead of leaning mostly on RAM, storage, and price.
Compare Devices now includes accuracy rows for screen, controls, portability, battery fit, and software fit.
Update 5 - Brands Pt. 2
5.7 - Mode Split
Added mode select so Recommendation and Compare Devices are split into their own flows.
The app now asks you to pick a mode before the other sections appear.
Compare Devices warns when a device has to fall back to an estimate.
5.6 - AYN Batch Storage
Thor and Odin 3 now reflect the current official AYN batch listings.
Current Thor Batch 6 and Odin 3 Batch 7 store listings now show UFS 3.1 instead of the earlier UFS 4.0 spec.
Storage and value scoring now factor that in with a small penalty, and the scorecard notes now call it out directly.
5.5 - Current Cleanup
Added RG406V to the live retro pool.
Fixed vertical retro tagging for devices like RGB20SX.
Preferences now show the current live pool after active filters.
Pre-order status now shows in more result cards.
Condensed the 5.x release notes.
5.4 - Form Factor Cleanup
Selected form factor now stays locked as a real pool filter.
Vertical form factor is now a real preference, and vertical retro buys no longer get treated like generic horizontal picks.
5.3 - Low End Retro Live
Added use case lanes and honest guardrails for low end retro.
Added live Powkiddy, Miyoo, ANBERNIC retro, and Miyoo Flip options.
Retro scoring now stays closer to cheap retro fits instead of drifting into Android overkill.
5.2 - Ownership Compare
Owned devices now get clearer upgrade, sidegrade, not worth it, and different lane comparisons.
Cross-brand family estimates now cover more non-live owned devices without falling back to note-only ownership.
5.1 - Preferences
Step 1 became Preferences with brand and form factor.
Brand now carries the strongest preference weight when the fit is close.
RAM and performance pressure now treat each selected system family like one representative game, while game count still scales storage.
5.0 - Live Brand Pool
Added the first live cross-brand pool built from current official AYN, Retroid, ANBERNIC, and AYANEO devices.
Official store price snapshots and pre-order labels now feed the live recommendation pool.

Future Roadmap
Roadmap updated for v.6.5.2 on 4/27/2026.
Battery and sustained load pass
Add real long session battery, thermal drop, and charging behavior notes so big recommendations stop looking equal when they are not.
OS and frontend maturity table
Track update cadence, sleep behavior, launcher quality, Android version, and community firmware support by family.
Exact per device playability grades
Push the system pass further with device specific grades so the app can separate broad chip strength from real 3DS, Switch, Wii, PS2, and dual screen fit.
